Interannual and decadal variability of the subtropical mode water formation in the South Pacific Ocean  

Science Journals Connector (OSTI)

The variability of the subtropical mode water (STMW) formation in the South Pacific Ocean from 1980 to 2004 is investigated in this study, using a high-resolution numerical model and a 3D Lagrangian trajectory model. Subduction rate, subduction-rate-weighted geometric centers and mean densities of mode waters all exhibit a significant interannual and decadal variability. The interannual change of the subduction rate is predominately due to the lateral induction, resulting from the strong spatial and temporal variations of the wintertime mixed layer depth. The upward trend in the subduction-rate-weighted mean density of western STMW is largely caused by the wintertime (September) cooling of the net heat flux in this area. Variations of subduction rate in the mode waters are closely linked to the El Niño-Southern Oscillation (ENSO) cycle. Two different methods of defining mode waters (fixed region versus thermodynamic approach) yield similar patterns of subduction rate and almost identical correlations with the annual Southern Oscillation Index. The eastern STMW could potentially affect the ENSO cycle through the interior communication window that was identified from the virtual streamfunction. Its location and width are closely related to the ENSO cycle. The deep westward penetration of the western edge of the window at the equatorial Pacific is evident during the 1998 La Niña event.

Why Sequence Subarctic Pacific Ocean?  

NLE Websites -- All DOE Office Websites (Extended Search)

Sequence Subarctic Pacific Ocean? Sequence Subarctic Pacific Ocean? The subarctic Pacific Ocean is one of the areas considered particularly vulnerable to acidification, which could affect the ocean's ability to act as a carbon sink. Global warming affects the food webs and biodiversity in marine ecosystems, especially in regions known as oxygen minimum zones where key components of the global carbon cycle take place. Oxygen minimum zones are found between 200 and 1,000 meters below sea level in the subarctic Pacific, the eastern South Pacific Ocean, the northern parts of the Indian Ocean and Arabian Sea, and off southwestern Africa. As global warming continues, researchers believe the oxygen levels in the oceans will decrease, a change that will extend the boundaries of the oxygen minimum

Infrasonic ambient ocean noise: Northeast Pacific Ocean  

Science Journals Connector (OSTI)

Measurements of ocean ambient noise were made at three widely separated deep?water bottom locations in the N. E. Pacific at eight frequencies in the range from 2.5–20.0 Hz for 40 consecutive days. Concurrent data on wind speed and wave height were collected. Analysis indicates that the spectrum level of infrasonicnoise is linearly related to the log of the wind speed above a threshold level. There is evidence that the noise can be directly associated with the wind rather than through the surface waves it produces. [Work supported by ONR.

Impact of mesoscale eddies on water transport between the Pacific Ocean and the Bering Sea  

E-Print Network (OSTI)

Sea surface height anomalies observed by satellites in 1993--2012 are combined with simulation and observations by surface drifters and Argo floats to study water flow pattern in the Near Strait (NS) connected the Pacific Ocean with the Bering Sea. Daily Lagrangian latitudinal maps, computed with the AVISO surface velocity field, and calculation of the transport across the strait show that the flow through the NS is highly variable and controlled by mesoscale and submesoscale eddies in the area. On the seasonal scale, the flux through the western part of the NR is negatively correlated with the flux through its eastern part ($r=-0.93$). On the interannual time scale, a significant positive correlation ($r=0.72$) is diagnosed between the NS transport and the wind stress in winter. Increased southward component of the wind stress decreases the northward water transport through the strait. Positive wind stress curl over the strait area in winter--spring generates the cyclonic circulation and thereby enhances the...

Sound propagation conditions in the equatorial South Pacific Ocean  

Science Journals Connector (OSTI)

A major part of the South Pacific Ocean is impacted by a cold water circulation induced by the Antarctic Circumpolar Current. This results in either a double or a very broad deep sound channel axis [R. N. Denham et al. J. Acoust. Soc. Am. 81 787–789 (1987)]. However nearer the equator this impact is reduced and a series of equatorial currents and counter currents come into play. An analysis is made of existing oceanographic data to determine the resulting sound?speed profile shape and sound channel axis depth. A comparison is made to profiles from the temperate regions of the South Pacific Ocean.

Low?Frequency Acoustic Attenuation in the South Pacific Ocean  

Science Journals Connector (OSTI)

The first known measurement of the attenuation of sound in deep water at frequencies below 1 kHz in the South Pacific Ocean is described. The receiver was situated off the east coast of the North Island of New Zealand. It was found that the attenuations are in most cases comparable with the values of attenuation measured in the North Pacific Ocean and the Atlantic Ocean between Bermuda and South America. However on one of the paths over which the attenuation was measured there was an abrupt change in the quality of sound transmission which is thought to be a result of the path crossing the Subtropical Convergence; south of this discontinuity the attenuations were found to be comparable with those obtained previously in the Southern Ocean.

Ocean noise in the tropical and subtropical Pacific Ocean  

Science Journals Connector (OSTI)

Ocean ambient noise is well studied in the North Pacific and North Atlantic but is poorly described for most of the worlds' oceans. Calibrated passive acoustic recordings were collected during 2009–2010 at seven locations in the central and western tropical and subtropical Pacific. Monthly and hourly mean power spectra (15–1000?Hz) were calculated in addition to their skewness kurtosis and percentile distributions. Overall ambient noise at these seven sites was 10–20?dB lower than reported recently for most other locations in the North Pacific. At frequencies 200?Hz with higher levels recorded in the winter than in the summer. Several species of baleen whales humpback (Megaptera novaeangliae) blue (Balaenoptera musculus) and fin (B. physalus) whales also contributed seasonally to ambient noise in characteristic frequency bands.

Spatial coherence measurement of sound in the northwest Pacific Ocean  

Science Journals Connector (OSTI)

An experiment on the transverse horizontal spatial coherence of sound propagating in the ocean was performed jointly by Chinese and Russian acousticians in the northwest Pacific Ocean in June 1990. Three hydrophones with spacings of 270 and 130 m were put in the water at a 30?m depth. The acoustic source with four cw (from 109 to 860 Hz) and a broadband pseudorandom noise signal was drifted at a depth of 100 m. Part of the measurement results of up to 140 km are presented in this paper. It seems that the spatial coherence was related to the amplitude of the received signals and rises considerably in convergence zones.

Sound Absorption in the Pacific Ocean  

Science Journals Connector (OSTI)

The absorption of sound in the Pacific Ocean at a nominal frequency of 75 kHz was measured over a horizontal path at depths of 910 and 3350 m. The results are 20.0±1.5 dB/km and 13.5±1.5 dB/km respectively which may be compared to values of 27.3 dB/km and 22.7 dB/km extrapolated from the empirical relation of Schulkin and Marsh. Evidently the useful range of this relation is severely limited. In addition the effect of pressure may be greater than previously suspected.

Distribution patterns of polychlorinated biphenyl congeners in water, sediment and biota from Midway Atoll (North Pacific Ocean)  

Science Journals Connector (OSTI)

To increase our understanding of critical pathways of polychlorinated biphenyl (PCB) transfer from abiotic media into marine organisms, this study quantified 20 PCB congeners in surface water, sediment and tissues of marine biota (macrophytes, snails, urchins, bivalves, sea cucumbers, fishes) taken from Midway Atoll. \\{PCBs\\} 138, 153, 170, 180 and 187 were the most abundant congeners in all samples analysed. Distribution of PCB congeners was shifted in favour of higher (hexa- and above) chlorinated congeners in all species; only aquatic macrophytes displayed significant bioaccumulation of lower (tri- and tetra-) chlorinated congeners. Evidence is presented for the differential metabolism of congeners by marine species. Non-ortho substituted congeners (PCBs 77, 126) with elevated toxic potency were not present at significant levels in the sampled species. Certain mono-ortho congeners (PCBs 105, 118), implicated in marine mammal toxicity, comprised only ?4.5% of total congener load in prey for piscivorous birds and marine mammals.

Ocean acoustic thermometry and the seasonal cycle of temperature in the North Pacific Ocean  

Science Journals Connector (OSTI)

With several years of long?range (several Mm) acoustic propagation data obtained during the Acoustic Thermometry of Ocean Climate (ATOC) and North Pacific Acoustic Laboratory (NPAL) projects the seasonal cycle of oceantemperature in the North Pacific can be examined. Acoustic transmissions have been made from a source located off the northern Californian coast and from a source located north of Kauai HI to several receivers of opportunity located in the North Pacific Basin. The acoustic data are a high signal?to?noise measure of large?scale temperature with excellent temporal resolution. Although only a few realizations of the seasonal cycle are available it is clear that inter? and intraannual variabilities are large contributions to the time series with signal amplitudes comparable to the seasonal cycle. Such variabilities are likely advective in origin. The time scales for some of the changes in temperature are short sometimes of order weeks. Not all available acoustic paths are suitable for assessing the seasonal cycle however. Near Hawaii the acoustic sampling does not extend to the near?surface waters so seasonal variations there are not measured. The acoustic results will be compared to measures of the seasonal cycle by satellite altimetry profiling floats and the ECCO numerical ocean model.

Pacific Ocean observation programs: Gaps in ecological time series  

Science Journals Connector (OSTI)

Abstract How well do existing ocean observation programs monitor the oceans through space and time? A meta-analysis of ocean observation programs in the Pacific Ocean was carried out to determine where and how key parameters defining the physics, chemistry, and biology of the oceans were measured. The analysis indicates that although the chemistry and physics of the Pacific Ocean are reasonably well monitored, ecological monitoring remains largely ad hoc, patchy, unsystematic, and inconsistent. The California Cooperative Oceanic Fisheries Investigations (CalCOFI), for example, is the only Pacific Ocean program in which the zooplankton and micronekton are resolved to species with consistent time series of greater than 20 years duration. Several studies now indicate massive changes to nearshore, mesopelagic and other fish communities of the southern California Current but available time series do not allow these potential changes to be examined more widely. Firm commitment from the global community to sustained, representative, quantitative marine observations at the species level is required to adequately assess the ecological status of the oceans.

Depth dependence of ambient noise in the northeastern Pacific Ocean  

Science Journals Connector (OSTI)

Omnidirectional ambient noise levels were measured at two deep?water locations in the northeastern Pacific Ocean.Hydrophones were positioned throughout the water column at depths ranging from about 200 m below the surface to about 150 m above the sea bottom. Analyses of the data over the frequencies from 15 to 800 Hz show that at low frequencies the noise levels decrease with increasing depth. The decrease with depth is greater below the critical depth than it is in the sound channel. These low?frequency noise levels and their depth dependence are independent of the wind speed. At higher frequencies the noise levels and the depth dependence are controlled by the wind?generated noise. At low wind speeds there is a decrease in levels below the critical depth but above this depth both increases and decreases in levels with depth were noted. At these high frequencies during high wind speeds the noise levels not only rise but also fill the water column to the extent that there is little decrease in level with increasing depth even for the region below the critical depth.

A pod of charges is lowered together with a hydrophone to various depths in the ocean and by observing the amount of scattered energy produced by detonating units of the explosive charge pod a profile of good resolution of the scattering strength versus depths obtained. The broad?band acoustic characteristics of the charges permit the spectral characteristics of the scattered returns to be determined. Observations made over an extended time period yield the time dependence of scattering. Measurements made in the northeast Pacific Ocean are given.

137Cs(90Sr) and Pu isotopes in the Pacific Ocean sources & trends  

SciTech Connect

The main source of artificial radioactivity in the world`s oceans can be attributed to worldwide fallout from atmospheric nuclear weapons testing. Measurements of selected artificial radionuclides in the Pacific Ocean were first conducted in the 1960`s where it was observed that fallout radioactivity had penetrated the deep ocean. Extensive studies carried out during the 1973-74 GEOSECS provided the first comprehensive data on the lateral and vertical distributions of {sup 9O}Sr, {sup 137}Cs and Pu isotopes in the Pacific on a basin wide scale. Estimates of radionuclide inventories in excess of amounts predicted to be delivered by global fallout alone were attributed to close-in fallout and tropospheric inputs from early U.S. tests conducted on Bikini and Enewetak Atolls in the Equatorial Pacific. In general, levels of fallout radionuclides (including {sup 9O}Sr, {sup 137}Cs and Pu isotopes) in the surface waters of the Pacific Ocean have decreased considerably over the past 4 decades and are now much more homogeneously distributed. Resuspension and the subsequent deposition of fallout radionuclides from previously deposited debris on land has become an important source term for the surface ocean. This can be clearly seen in measurements of fallout radionuclides in mineral aerosols over the Korean Peninsula (Yellow dust events). Radionuclides may also be transported from land to sea in river runoff-these transport mechanisms are more important in the Pacific Ocean where large quantities of river water and suspended sands/fluvial sediments reach the coastal zone. Another unique source of artificial radionuclides in the Pacific Ocean is derived from the slow resolubilization and transport of radionuclides deposited in contaminated lagoon and slope sediments near U.S. and French test sites. Although there is a small but significant flux of artificial radionuclides depositing on the sea floor, > 80% of the total 239, {sup 240}Pu inventory and > 95% of the total {sup 137}Cs inventory remains in the water column. Studies conducted through the 1980`s appear to be consistent with earlier findings and indicate that radionuclide inventories in mid-northern latitudes are at least a factor of two above those expected from global fallout alone. The long term persistence of close-in and/or stratospheric fallout from nuclear weapons testing in the Marshall Islands still appears to be the only plausible explanation for this anomaly.

Subsidies to tuna fisheries in the Western Central Pacific Ocean  

Science Journals Connector (OSTI)

Abstract Tuna fisheries in the Western and Central Pacific Ocean are among the most valuable resources in the region. These fisheries, worth an estimated $4.1 billion each year, play a pivotal role in supporting incomes and development goals in the region. However, due to the twin, and potentially inter-related effects of harmful fishing practices such as the use of fish aggregating devices, overcapacity, and fisheries subsidies, many of these tuna fisheries are currently at risk of over-exploitation—putting the livelihoods of countless local fishers at risk. This study finds that government fisheries subsidies in the region represent 37% of the ex-vessel value of tuna fisheries in the region. Fuel subsidies are estimated at US$ 335 million and non-fuel subsidies are estimated at US$ 1.2 billion for the year 2009. Developed countries are responsible for more than half of the subsidies spent in the predominantly developing region, underlying the fact that the majority of tuna value extracted from the national waters of developing countries in the region benefit larger, developed countries. The total resource rent, or return to society, from tuna fisheries, once adjusted for subsidies is a net negative US$750 million in 2009. Fisheries subsidies are enabling foreign fleets to operate at sub-market rates, putting local fleets out of competition for their own fishery resources.

Contribution of iceberg sounds to the ambient noise budget in the South Pacific Ocean  

Science Journals Connector (OSTI)

On May 2002 C19 a 5500 km2 iceberg calved from the Ross Ice Shelf eventually drifting eastward into the open Pacific Ocean by 2008. As it sailed into warmer waters thermal and wind stresses caused the iceberg to crack and break apart. These resulting “icequakes” projected wideband acoustic energy into the water column influencing the regional ambient noise environment. Icequake noise was persistent and strong enough to be observed by NOAA’s eastern equatorial Pacific moored hydrophone (EEP-NW at 8N 110W) as well as the hydroacoustic station of International Monitoring System (IMS) on Juan Fernandez Island (H03N at 33.44S 78.91W). Elevated noise levels (maximum of ~+3 dB at NOAA’s EEP and ~+7 dB at IMS H03N hydrophones) were observed by both stations from early 2008 when C19a first appeared in the Pacific until it drifted into the Atlantic Ocean in early 2009. C19a’s icequake and calving activity was also most frequent during this same period. Seasonal changes and long-term trends in ambient noise levels at NOAA’s EEP-NW acoustic mooring (1996–2009) and IMS Juan Fernandez (2003–2010 years) and the unique acoustic role icebergs play in the Southern Ocean will be presented.

Sperm whale coda repertoires in the western Pacific Ocean  

Science Journals Connector (OSTI)

Sperm whales are social cetaceans that live in matrilineal family units and inhabit all major ocean basins from the tropics to polar regions. They produce stereotyped patterns of 3 to 40 broadband clicks termed “codas ” that typically occur within a period of less than 3 s. Coda repertoires can be assigned to a “vocal clan ” a type of social group used to define sperm whale population structure. Extensive studies of vocal clans have been conducted in the eastern tropical Pacific (ETP); however little is known about sperm whale coda repertoires in the western Pacific. We reviewed codas recorded from independent sperm whale groups that were acoustically and visually encountered during two marine mammal surveys conducted in the Northern Mariana Islands (10 groups) and Palau region (3 groups) in 2007 and 2012 respectively. Three bioacousticians qualitatively classified codas to type which indicated the presence of the “+1” and “regular” vocal clan. These data are now being analyzed using multivariate methods described by Rendell and Whitehead (2003) to quantitatively classify codas from each group. The identification of vocal clans within this region has implications for understanding the culturally linked stock distribution of sperm whales across the Pacific Ocean.

Analysis of sailfish (Istiophorus platypterus) population structure in the North Pacific Ocean  

Science Journals Connector (OSTI)

Abstract The global genetic population structure of sailfish is not well understood, nor has it been well characterized in any of the major ocean basins. In this study, we surveyed the pattern of genetic differentiation of sailfish in the North Pacific Ocean using 307 bp of sequence of the mtDNA control region I and five tetra-nucleotide microsatellite loci for 92 sailfish representing three North Pacific localities. We report significant genetic differentiation with both mitochondrial and nuclear markers between the western North Pacific Ocean collection from Taiwan (n = 39) and the eastern North Pacific Ocean collections from Mexico (n = 37) and Costa Rica (n = 16), the latter of which were not significantly different from each other. These results corroborate genetic heterogeneity in the North Pacific previously observed using restriction fragment length polymorphisms (RFLPs) of mtDNA, and three microsatellite loci, and indicate that sailfish from the eastern and the western North Pacific Ocean belong to distinct populations. Consistent with the levels of mtDNA variation reported in other marine species, sailfish in the eastern Pacific Ocean displayed significantly (p Pacific Ocean. In future studies, sample sizes and geographic coverage should be increased to resolve the population structure throughout the entire Pacific Ocean.

Chapter 11 - Managing Multiple Human Stressors in the Ocean: A Case Study in the Pacific Ocean  

Science Journals Connector (OSTI)

Abstract The Pacific Ocean represents almost half of the world’s total ocean area, contains every major variety of marine habitats, and borders the coastline of 50 countries or territories. The huge variety of habitat types, ranging from shallow coasts to the abyssal regions that reach thousands of meters in depth, and including coral reefs, seagrass, mangroves, and estuaries, hosts an immeasurable diversity of organisms. This biodiversity and these ecosystems provide a wide range of services for human society with hundreds of billions of dollars of vital services every year and play an important role in the lives and traditions of its coastal and island inhabitants. For example, more than half of reported global fisheries landings are caught in the Pacific Ocean, providing annual gross revenues amounting to approximately US$50 billion every year. However, today, fisheries resources in the Pacific Ocean are generally fully or overexploited. There are many challenges to overcome if the sustainable management of fisheries resources in the Pacific is to be achieved, including the lack of well-defined and enforced access rights; “bad” subsidies, which intensify overcapitalization; illegal, unreported, and unregulated fishing, which distorts markets and makes accurate stock assessments impossible; and, perhaps most fundamentally, the inherent tendency to focus on short-term benefits at the expense of long-term conservation. In addition, climate change is now considered one of the major drivers of change in the Pacific, affecting the sustainability of ecosystem services. Many regions of the Pacific have already experienced the effects of climate change. The full impacts of the synergistic effects of multiple factors, including pollution and habitat destruction, are not yet fully understood. This further highlights the urgent need to address and prepare for the threat of multiple climate and environmental stressors on coastal communities and on the marine fisheries so vital to their lives and livelihoods. Solutions to these challenges must be holistic, multisectoral, and cross-scale, putting into effect the concept of optimizing a complex system presented in Chapter 8. It is vital that the region moves toward ecosystem-based management where multiple threats are addressed within integrated strategies.

Acoustic monitoring of severe weather in the Northeast Pacific Ocean.  

Science Journals Connector (OSTI)

Wind and rainfall are the principal physical processes responsible for the production of high?frequency (1–50 kHz) ambient sound in the ocean. The primary source of the sound is the resonant ringing of individual bubbles created during wave breaking and raindrop splashes. Larger bubbles (>300 ?m diameter) quickly return to the surface while smaller bubbles can be mixed downward at several meters. During severe weather a layer of smaller ambient bubble forms and effectively absorbs higher?frequency (>10 kHz) sound. These processes are revealed in a two?year record of ambient sound recorded from a subsurface mooring at 50N 145W in the NE Pacific Ocean as part of the Canadian SOLAS program. The passive acoustic signal of wind rain and ambient bubbleclouds are compared to the subsurface mooring data including data from an upward looking 200 kHz active sonar and a 300 kHz ADCP. The acoustic signatures of light moderate and heavy rainfall are superimposed on the signature of high wind demonstrating rainfall detection even in the presence of high wind.

Pressure dependence of sound attenuation in the Pacific Ocean  

Science Journals Connector (OSTI)

Measurements of the attenuation of sound at a nominal frequency of 75 kHz have been made over vertical and horizontal acoustic paths located between depths of 700 and 3400 m in the Pacific Ocean. Results indicate that the equation used to predict attenuation overestimates the values actually encountered at these frequencies and depths. (Compare calculated values of 27.3 and 22.7 dB/km to measured values of 19.9±0.5 and 13.3±0.5 dB/km at depths of 910 and 3350 m respectively.) The measurements definitely establish the decrease of attenuation with increasing pressure. However the magnitude of the pressure coefficient of attenuation is almost twice as large as previously suspected (12.3±1.1×10?4/bar or approximately 12.3×10?4/atm compared to 6.54×10?4/atm).

Signals from SUS bombs were received at four hydrophones suspended in the deep ocean from the Research Platform FLIP. Using digital processing equipment and fast Fourier transform methods energy?flux spectral densities were determined for approximately 700 shots out to a maximum range of 1600 nautical miles. Differences in propagation losses at various octave and one?third?octave frequency bands up to 400 Hz were used to calculate attenuation values. The resulting values are lower than those predicted from Thorp's equation but are in agreement with published values determined from cw acoustic transmission experiments in the Northeastern Pacific [J.

The confirmed distribution of P. pusilla in the Pacific Ocean is limited to Australia, Hawaii, and Panama, despite earlier published reports from Chile and China. Laboratory experiments demonstrated intolerance of P. pusilla to freshwater, causing 100% mortality, and suggest invasion of the Pacific coast of Panama occurred through the Canal via ships' ballast water or by secondary spread via ships (ballast water or hull fouling) from another Pacific region.

Low frequency deep ocean ambient noise trend in the Northeast Pacific Ocean  

Science Journals Connector (OSTI)

Concern about effects of anthropogenic noise on marine life has stimulated new studies to establish present-day oceannoise levels and compare them to noise levels from previous times. This paper reports on the trend in low-frequency (10–400 Hz) ambient noise levels and presents measurements made using a calibrated multi-element volume array at deep ocean sites in the Northeast Pacific from 1978 to 1986. The experiments provided spectral noise levels as well as horizontal and vertical noise directionality. The data presented here provide evidence that the trend derived from 1960s data extended to around 1980 but has since continued at a lower rate.

SOFAR propagation conditions in the Subarctic Northeast Pacific Ocean  

Science Journals Connector (OSTI)

An analysis of two extensive sound speed profile surveys (winter and summer) of the subarctic region (above 40° N) in the Northeast Pacific Ocean shows that the depth of the deep sound channel axis is symmetric about the Alaskan Gyre (centered at 53° N 153° W). The axis depth ranges from 100 m or less in the Gyre to 400 m or more along the coast of North America. A model for axis depth contours is developed which has some interesting results. For example a north?south track along 140° W has little change of axis depth with latitude while an east?west track along 53° N would have a significant change in axis depth. An estimate of the yearly variability of the model is made from long?term oceanographic data obtained at weather station “Papa” (50° N 145° W). Sound propagation loss is computed for selected tracks using a range?dependent acoustic prediction model and these results are compared to experimental data.

Ocean-color radiometry across the Southern Atlantic and Southeastern Pacific: Accuracy and remote sensing implications  

Science Journals Connector (OSTI)

Abstract Ocean color radiometry (OCR) provides valuable data for biogeochemical oceanography. In situ OCR measurements are used in the development and validation of bio-optical models and vicarious calibration of satellite ocean-color sensors. It is thus crucial to obtain accurate in situ OCR measurements, which is a challenge, especially in regions subjected to adverse environmental conditions and where waters are optically complex. In the present work, the accuracy of in situ OCR is analyzed with data acquired in a wide range of bio-geographic provinces across the Southern Atlantic and Southeastern Pacific during the R/V Melville MV1102 cruise. Varied techniques employed to measure above-water remote sensing reflectance (Rrs) are inter-compared. Measured Rrs is also compared with modeled Rrs in a closure experiment. The impact of Rrs uncertainties on the retrieval of chlorophyll a concentration (Chla) and inherent optical properties (IOPs) is evaluated using operational bio-optical algorithms. The relative percent difference (RPD) between Rrs measured by the various techniques ranged from 12 to 26% for the ocean-color bands (412–555 nm), and 3–12% for the ratios (412–510/555). A merged Rrs obtained by averaging the different types of measurements, INS, is recommended to reduce uncertainties. The coefficient of variation of INS and reflectance ratios was 11–13% and 3–5%, respectively. The RPD between INS and modeled Rrs and the corresponding ratios ranged from 18 to 34% and from 13 to 17%, respectively. Complete closure could not be obtained due to both measurement and modeling uncertainties. The impact of INS uncertainties on retrieved Chla and \\{IOPs\\} was generally smaller than the intrinsic errors of the inversion schemes. The results suggest that even though more accurate ocean-color radiometry is desirable, improving retrieval algorithms is essential to properly describing and furthering our understanding of bio-optical variability in the world's oceans.

Model simulations on the long-term dispersal of 137Cs released into the Pacific Ocean off Fukushima  

Science Journals Connector (OSTI)

A sequence of global ocean circulation models, with horizontal mesh sizes of 0.5°, 0.25° and 0.1°, are used to estimate the long-term dispersion by ocean currents and mesoscale eddies of a slowly decaying tracer (half-life of 30 years, comparable to that of 137Cs) from the local waters off the Fukushima Dai-ichi Nuclear Power Plants. The tracer was continuously injected into the coastal waters over some weeks; its subsequent spreading and dilution in the Pacific Ocean was then simulated for 10 years. The simulations do not include any data assimilation, and thus, do not account for the actual state of the local ocean currents during the release of highly contaminated water from the damaged plants in March–April 2011. An ensemble differing in initial current distributions illustrates their importance for the tracer patterns evolving during the first months, but suggests a minor relevance for the large-scale tracer distributions after 2–3 years. By then the tracer cloud has penetrated to depths of more than 400 m, spanning the western and central North Pacific between 25°N and 55°N, leading to a rapid dilution of concentrations. The rate of dilution declines in the following years, while the main tracer patch propagates eastward across the Pacific Ocean, reaching the coastal waters of North America after about 5–6 years. Tentatively assuming a value of 10 PBq for the net 137Cs input during the first weeks after the Fukushima incident, the simulation suggests a rapid dilution of peak radioactivity values to about 10 Bq m?3 during the first two years, followed by a gradual decline to 1–2 Bq m?3 over the next 4–7 years. The total peak radioactivity levels would then still be about twice the pre-Fukushima values.

Contour Charts of SOFAR Speed and Axis Depth in the Pacific Ocean  

Science Journals Connector (OSTI)

Sound speeds calculated from the physical properties of sea water as measured at hydrographic stations were used to construct contour charts of SOFAR?speed and SOFAR?axis depth for the Pacific Ocean. Wilson's formula was used for the calculation of speed. Data were averaged for 1° squares plotted and smooth contours were drawn manually. Speeds averaged along great?circle paths are compared with those measured for explosions. The charts show steep gradients along the Antarctic convergence and at the convergence of the Oyashio and Kuroshio extension. The region of highest speed as well as greatest axis depth was that extending eastward from Australia to about the 150°W. The charts are used in a program for calculating source coordinates of earthquakeT phases.

Fin whale song characteristics recorded on ocean bottom seismometers in the Northeast Pacific Ocean  

Science Journals Connector (OSTI)

Fin whales produce low frequency sequences of vocalizations that can be detected opportunistically on ocean bottom seismometers (OBSs). Using an automatic detection algorithm we have analyzed fin whale calls recorded on OBSs in the Northeast Pacific Ocean over broad spatial and temporal scales. The Cascadia Initiative experiment consists of 70 OBSs deployed for a total of four years (2011–2015). It extends from Vancouver Island to Cape Mendocino and several hundred kilometers offshore. Additional OBS data that overlap spatially with the northern portion of the Cascadia Initiative instruments are available from the Neptune Canada cabled observatory which has been online since 2009 and from standalone deployments between 2003 and 2006. With this study we examine call characteristics and seasonal call counts for patterns that might indicate migratory movements or distinct acoustic populations. Both frequency and inter-pulse interval (IPI) are automatically extracted for each detected call and seasonal and inter-annual calling patterns are examined using daily binned call count histograms. Preliminary analysis of a subset of Cascadia Initiative data from 2011 to 2013 shows a dominant sequence of alternating classic and backbeat calls at center frequencies of 20 and 18.5 Hz respectively and preceding IPIs of 16 and 18 s respectively.

This technical note describes a database of tidal elevation boundary condition information generated in support of the `Long-Term Fate of Dredged Material Disposed in Open Water` research of the Dredging Research Program (DRP), being conducted at the U.S. Army Engineer Waterways Experiment Station. The database, described in detail by Hench and others (1994), allows the user to manually generate time series of tidal elevations or to use a program to access the full database to generate time series of both tidal elevations and currents for any location along the West Coast of the United States and Eastern North Pacific Ocean, extending from Seal Cape on Unimak Island, Alaska, in the North to Punta Parada, Peru, in the South. The land boundary includes the Pacific shorelines of Alaska, Canada, mainland United States, Mexico, Guatemala, El Salvador, Nicaragua, Costa Rica, Panama, Columbia, and Northern Peru. Although the capability to generate these time series was developed to provide input to the Long-Term Fate and Stability Model (LTFATE), the generated time series can be used for any application requiring tidal forcing data.

Here we show, using an analysis of a string of observational data sets, that the variability of the thermocline depth (TD) in the east Pacific exerts a significant degree of control on the variability of PDI in that region. On average, a deep thermocline with a larger reservoir of heat favors TC intensification by reducing SST cooling while a shallow thermocline with a smaller heat reservoir promotes enhanced SST cooling that contributes to TC decay. At interannual time scales, the variability of basin-mean TD accounts for nearly 30% of the variability in the PDI during the TC season. Also, about 20% of the interannual variability in the east Pacific basin-mean TD is due to the El Niño and the Southern Oscillation (ENSO), a dominant climate signal in this region. This study suggests that a better understanding of the factors governing the interannual variability of the TD conditions in the east Pacific and how they may change over time, may lead to an improved projection of future east Pacific TC activity.

Nonperturbative ocean acoustic tomography inversion of 1000?km pulse propagation in the Pacific Ocean  

Science Journals Connector (OSTI)

A nonperturbative inversion was performed of acoustic tomographymeasurements made in the northeastern Pacific Ocean in July 1989 in which acoustic transmissions from a 250?Hz broadband source located near the sound?channel axis were recorded at a long vertical array of hydrophones 1000 km away. In contrast with a conventional inversion this nonperturbative inversion does not assume that travel times are linearly related to the sound?speed deviations from a background sound?speed model. The inversion process involved three steps: (1) Measured pulse travel times and the source and receiver locations were used to determine the range average of the equivalent symmetric sound?slowness profile. That part of the inversion used only curve fitting and Abel transforms and required independent (nontomographic) information only to help identify the pulse arrivals. (2) Under the assumption that the range dependence of sound speed was small we used the reciprocal of the range?averaged sound?slowness profile to approximate the range average of the sound?speed profile. (3) Constraining the sound speed below the sound?channel axis to match climatological data and neglecting the range dependence of sound speed below the sound?channel axis allowed us to estimate the range average of the sound?speed profile above the sound?channel axis. This inversion was compared with the range average of sound speed calculated from CTD measurements made during the experiment over a 10?day period. The agreement was good between 50? and 300?m depths but there were some disagreements near the surface and near the sound?channel axis.

Task 3: PNNL Visit by JAEA Researchers to Participate in TODAM Code Applications to Fukushima Rivers and to Evaluate the Feasibility of Adaptation of FLESCOT Code to Simulate Radionuclide Transport in the Pacific Ocean Coastal Water Around Fukushima  

SciTech Connect

Four JAEA researchers visited PNNL for two weeks in February, 2013 to learn the PNNL-developed, unsteady, one-dimensional, river model, TODAM and the PNNL-developed, time-dependent, three dimensional, coastal water model, FLESCOT. These codes predict sediment and contaminant concentrations by accounting sediment-radionuclide interactions, e.g., adsorption/desorption and transport-deposition-resuspension of sediment-sorbed radionuclides. The objective of the river and coastal water modeling is to simulate • 134Cs and 137Cs migration in Fukushima rivers and the coastal water, and • their accumulation in the river and ocean bed along the Fukushima coast. Forecasting the future cesium behavior in the river and coastal water under various scenarios would enable JAEA to assess the effectiveness of various on-land remediation activities and if required, possible river and coastal water clean-up operations to reduce the contamination of the river and coastal water, agricultural products, fish and other aquatic biota. PNNL presented the following during the JAEA visit to PNNL: • TODAM and FLESCOT’s theories and mathematical formulations • TODAM and FLESCOT model structures • Past TODAM and FLESCOT applications • Demonstrating these two codes' capabilities by applying them to simple hypothetical river and coastal water cases. • Initial application of TODAM to the Ukedo River in Fukushima and JAEA researchers' participation in its modeling. PNNL also presented the relevant topics relevant to Fukushima environmental assessment and remediation, including • PNNL molecular modeling and EMSL computer facilities • Cesium adsorption/desorption characteristics • Experiences of connecting molecular science research results to macro model applications to the environment • EMSL tour • Hanford Site road tour. PNNL and JAEA also developed future course of actions for joint research projects on the Fukushima environmental and remediation assessments.

North Pacific Mesoscale Coupled Air-Ocean Simulations Compared with Observations  

SciTech Connect

Executive summary The main objective of the study was to investigate atmospheric and ocean interaction processes in the western Pacific and, in particular, effects of significant ocean heat loss in the Kuroshio and Kuroshio Extension regions on the lower and upper atmosphere. It is yet to be determined how significant are these processes are on climate scales. The understanding of these processes led us also to development of the methodology of coupling the Weather and Research Forecasting model with the Parallel Ocean Program model for western Pacific regional weather and climate simulations. We tested NCAR-developed research software Coupler 7 for coupling of the WRF and POP models and assessed its usability for regional-scale applications. We completed test simulations using the Coupler 7 framework, but implemented a standard WRF model code with options for both one- and two-way mode coupling. This type of coupling will allow us to seamlessly incorporate new WRF updates and versions in the future. We also performed a long-term WRF simulation (15 years) covering the entire North Pacific as well as high-resolution simulations of a case study which included extreme ocean heat losses in the Kuroshio and Kuroshio Extension regions. Since the extreme ocean heat loss occurs during winter cold air outbreaks (CAO), we simulated and analyzed a case study of a severe CAO event in January 2000 in detail. We found that the ocean heat loss induced by CAOs is amplified by additional advection from mesocyclones forming on the southern part of the Japan Sea. Large scale synoptic patterns with anomalously strong anticyclone over Siberia and Mongolia, deep Aleutian Low, and the Pacific subtropical ridge are a crucial setup for the CAO. It was found that the onset of the CAO is related to the breaking of atmospheric Rossby waves and vertical transport of vorticity that facilitates meridional advection. The study also indicates that intrinsic parameterization of the surface fluxes within the WRF model needs more evaluation and analysis.

Distributed acoustical assimilation in the equatorial Pacific Ocean  

Science Journals Connector (OSTI)

The possibility of using a dynamical?model?based equatorial oceandata assimilation technique as the basis for tomographic inversion is explored. In the equatorial Pacific relatively few ray paths come near the surface causing difficulty for most inversion techniques. A data assimilation technique being developed at the Physical Oceanography Division of AOML/NOAA [Thacker and Long in preparation] uses a dynamical approach that can provide coupling between the deep conditions that are directly sensed by the acoustics and the near surface events that are of direct climatic significance. The model decomposes temperature variability into dynamical modes identifiable with Kelvin and Rossby waves; the sensitivity of individual ray?path travel times to the modes is used as the basis for the inversion. The acoustic data is assimilated with other oceanmeasurements by using a LaGrange multiplier approach constrained by the dynamics. Ray tracing results using equatorial Pacific temperature data are presented which show the promise of dynamical?model assimilation based tomographic inversion as a means of detecting near surface temperature anomalies in the equatorial Pacific.

Volume Scattering of Acoustic Waves in the N. E. Pacific Ocean  

Science Journals Connector (OSTI)

Two types of scattering strength measurements have been obtained in the N. E. Pacific Ocean in deep water approximately 100 NM west of the entrance to the Strait of Juan de Fuca. The first type is obtained using surface venting explosive charges with the listening hydrophone suspended near the surface (i.e. depth <50 ft) to measure the backscattered acoustic energy. Levels of the intensity time curves so observed yield the scattering strength integrated to the depth corresponding to the time coordinate on the decay curve i.e. ? z?d z? O m r ?(z)?dz while the decay rates yield information on the scattering distribution in the medium. The second type of scattering measurement obtained is the scattering strength profile. Such profiles are obtained using near monostatic fired charge and receiver placed at various depths. Observation of the close?in scattered returns permits adequate resolution to plot scattering profiles through most layers [i.e. mv (z) z=0+d ]. Both sets of measurements show the diurnal migration of the scattering layers as well as the frequency characteristics. However the technique of measuring the scattering strength profile is the more direct and yields a better picture of layer distributions and the depth dependence of the scattering spectra.

Regional dependence of low?frequency attenuation in the North Pacific Ocean  

Science Journals Connector (OSTI)

A number of experiments based in the South Pacific Ocean have now been reported in which the attenuation of underwater sound at very?low?frequencies displays an apparent regional dependence providing a possible explanation for the considerable spread in at sea attenuation measurements below 1kHz. This regional dependence has been interpreted in terms of acoustic scattering from oceanographic inhomogeneities of various forms and at least two recent theoretical variants based on such a mechanism have been proposed. This paper presents evidence of a similar regional dependency in the North Pacific Ocean and examines the significance of the data to the two theoretical treatments currently most successful in accounting for the effects observed.

Global Climate network evolves with North Atlantic Oscillation phases: Coupling to Southern Pacific Ocean  

E-Print Network (OSTI)

We construct a network from climate records of atmospheric temperature at surface level, at different geographical sites in the globe, using reanalysis data from years 1948-2010. We find that the network correlates with the North Atlantic Oscillation (NAO), both locally in the north Atlantic, and through coupling to the southern Pacific Ocean. The existence of tele-connection links between those areas and their stability over time allows us to suggest a possible physical explanation for this phenomenon.

Sound propagation over Dickins Seamount in the Northeast Pacific Ocean  

Science Journals Connector (OSTI)

The acoustic propagation losses between a 230?Hz cw source and a multi?hydrophone receiving system were measured over Dickins Seamount in the Northeast Pacific. The source was towed at depths of 18 and 184 m. The receiving system had hydrophones spaced in depth from 323 to 633 m. The measurements were made to a maximum range of 130 km with the receiver located at a range of 60 km from the seamount peak. The results show that the seamount cast an acoustic shadow over the receiver increasing the propagation loss by up to 15 dB when the source was shallow and in a position which enabled the seamount to intercept all of the deep refracted source energy. Back reflections from the seamount with levels 6 to 13 dB below the direct signal level were present when the shallow source was 3 to 5 km from the seamount peak. Downslope reflections enhanced the direct signal by up to 10 dB when the shallow source was within 3 km of the peak. Acoustic shadowing and reflection effects were minimal in the results for the deep source because most of the source energy propagated along the sound?channel axis above the seamount peak. The analysis indicates that ray theory is adequate for describing the reflection effects of the acoustic propagation but does not account for all of the acoustic energy in the shadow zone.

Mode coherence at megameter ranges in the North Pacific Ocean  

Science Journals Connector (OSTI)

This article analyzes the coherence of low-mode signals at ranges of 3515 and 5171 km using data from the Acoustic Thermometry of Ocean Climate (ATOC) and Alternate Source Test (AST) experiments. Vertical line arrays at Hawaii and Kiritimati received M-sequences transmitted from two sources: the 75-Hz bottom-mounted ATOC source on Pioneer Seamount and the near-axial dual-frequency (28/84 Hz) AST source deployed nearby. This study demonstrates that the characteristics of the mode signals at 5171-km range are quite similar to those at 3515-km range. At 75 Hz the mode time spreads are on the order of 1.5 s implying a coherence bandwidth of 0.67 Hz. The time spread of the 28-Hz signals is somewhat lower but these signals show significantly less frequency-selective fading than the 75-Hz signals suggesting that at the lower frequency the multipaths are temporally resolvable. Coherence times for mode 1 at 75 Hz are on the order of 8 min for the 3515-km range and 6 min for 5171-km range. At 28 Hz mode 1 is much more stable with a magnitude-squared coherence of greater than 0.6 for the 20-min transmission period.

Very?low?frequency scattering by abyssal hills of the Pacific Ocean  

Science Journals Connector (OSTI)

Tectonic forces operating on the upper crust over its first million years (within about 20 km of the crest of the East Pacific Rise EPR) give rise to a “horst and grabben” structure that hypothetically remains frozen as the plates advance across the Pacific Ocean. The horsts (uplifted plateaus) and grabben (valleys) striate the Pacific bottom in a nearly north?south direction. Scripps deep tow measurements at a nearly sediment?free site about 30 km from the EPR reveal that the number height and width of the horsts are nominally 2/km 60 m and 600 m respectively. Twersky's theory of scattering from elliptically striated surfaces appears to be appropriate for estimating/investigating scattering loss and modal stripping caused by this type of bottom. Examples of calculations will be presented at infrasonic frequencies. The resultant computations constitute real world predictions provided that the acoustic wavelength exceeds the thickness of the sediments overlaying the basalt. In the majority of the Pacific the nominal sediment thickness is less than 100 m and the corresponding frequency range is below 15 Hz.

Assessment of storage lipid accumulation patterns in eucalanoid copepods from the eastern tropical Pacific Ocean  

Science Journals Connector (OSTI)

Abstract Members of the copepod family Eucalanidae are widely distributed throughout the world?s oceans and have been noted for their accumulation of storage lipids in high- and low-latitude environments. However, little is known about the lipid composition of eucalanoid copepods in low-latitude environments. The purpose of this study was to examine fatty acid and alcohol profiles in the storage lipids (wax esters and triacylglycerols) of Eucalanus inermis, Rhincalanus rostrifrons, R. nasutus, Pareucalanus attenuatus, and Subeucalanus subtenuis, collected primarily in the eastern tropical north Pacific near the Tehuantepec Bowl and Costa Rica Dome regions, noted for its oxygen minimum zone, during fall 2007 and winter 2008/2009. Adult copepods and particulate material were collected in the upper 50 m and from 200 to 300 m in the upper oxycline. Lipid profiles of particulate matter were generated to help ascertain information on ecological strategies of these species and on differential accumulation of dietary and modified fatty acids in the wax ester and triacylglycerol storage lipid components of these copepods in relation to their vertical distributions around the oxygen minimum zone. Additional data on phospholipid fatty acid and sterol/fatty alcohol fractions were also generated to obtain a comprehensive lipid data set for each sample. Rhincalanus spp. accumulated relatively large amounts of storage lipids (31–80% of dry mass (DM)), while E. inermis had moderate amounts (2–9% DM), and P. attenuatus and S. subtenuis had low quantities of storage lipid (0–1% DM). E. inermis and S. subtenuis primarily accumulated triacylglycerols (>90% of storage lipids), while P. attenuatus and Rhincalanus spp. primarily accumulated wax esters (>84% of storage lipids). Based on previously generated molecular phylogenies of the Eucalanidae family, these results appear to support genetic predisposition as a major factor explaining why a given species accumulates primarily triacylglycerols or wax esters, and also potentially dictating major fatty acid and alcohol accumulation patterns within the more highly modified wax ester fraction. Comparisons of fatty acid profiles between triacylglycerol and wax ester components in copepods with that in available prey suggested that copepod triacylglycerols were more reflective of dietary fatty acids, while wax esters contained a higher proportion of modified or de novo synthesized forms. Sterols and phospholipid fatty acids were similar between species, confirming high levels of regulation within these components. Similarities between triacylglycerol fatty acid profiles of E. inermis collected in surface waters and at >200 m depth indicate little to no feeding during their ontogenetic migration to deeper, low-oxygen waters.

Pressure Dependence of High?Frequency Sound Attenuation in the Deep Pacific Ocean  

Science Journals Connector (OSTI)

Vertical and horizontal acoustic paths located in the Pacific Ocean between depths of 910 and 3350 m have been utilized to determine the attenuation of sound at a nominal frequency of 75 kHz. Results from these two different geometries show that predicted values exceed the observed magnitudes of acoustic attenuation at this frequency and at these depths. At 3350 m the predicted value is 22.7 dB/km vs a measured value of 13.3±0.5 dB/km a discrepancy of more than 9 dB. Furthermore increasing pressure reduces the attenuation a fact which supports the work of Fisher [J. Acoust. Soc. Amer. 38 805 (1965)] in contrast to that of Kester and Pytkowicz [Geochimica et Cosmochimica Acta 34 1039 (1970)]. However the amount of reduction is larger than previously suspected by more than 80% [This paper represents results of research sponsored by the Office of Naval Research.

Site and frequency dependence of ambient noise in the Northeastern Pacific Ocean  

Science Journals Connector (OSTI)

One?hour averages of omidirectional ambient noise measurements at 60 and 165 Hz are analyzed for two nearby deep ocean sites in the Northeastern Pacific during February and March 1981. Site A is a high noise site and is located near major east–west shipping lanes and near major Pacific storm paths. Site B is a lower noise site and is located approximately 450 nm from site A away from major shipping lanes and near major Pacific storm paths. The site and frequency dependence of ambient noise is found to be highly variable with shipping noise being totally dominant at 60 Hz at site A and stormnoise being totally dominant at 165 Hz at site B. Both shipping and stormnoise can dominate the 165?Hz site A or 60?Hz site B noise levels depending on weather conditions. Storms have a possible indirect effect on shipping noise since very low noise periods occur in between storms especially when the storm passes nearby the site. A limited number of WMO ships sampled indicate that ships slow down or stay in port during storms. Average omnidirectinal noise levels at 60 Hz at both sites and at 165 Hz at site A were 3 to 4 dB lower during a stormy week than they were during a relatively calm week. Array noise gain measurements at site B indicate that the coherence of noise during stormy periods is much less than it is during calm periods. Generally this implies that the increase in beam level at 165 Hz caused by stormnoise will be significantly less than corresponding increase in omnidirectional noise levels.

Bill Watkins listens to all the whales in the North Pacific Ocean  

Science Journals Connector (OSTI)

In the early 1990s portions of the Navy’s classified underwater listening systems (IUSS) were made available for research. Bill Watkins had long been familiar with this system and eagerly went to work listening to whales in the North Pacific Ocean. A decade later the work that Bill Watkins has amassed and its impact on marine mammal research is truly remarkable. Each month Bill’s team produces a summary of hundreds if not thousands of whale calls detected and localized using the Navy’s listening arrays. These data have pinpointed seasonal centers of vocal activity in unexpected places leading to changes in our strategies for monitoring several populations of endangered large whales. Bill has tracked the migratory paths of blue fin and humpback whales and has charted the shifts in migratory timing caused by climatic phenomena such as ENSO. Bill has taken a complex technology created for other purposes and crafted a process to get it to deliver simple clear and unclassified information for an entire ocean: we have not yet plumbed the limits of what we can do with this information.

Perspectives on Temperature in the Pacific Northwest's Fresh Waters  

SciTech Connect

This report provides a perspective on environmental water temperatures in the Pacific Northwest as they relate to the establishment of water temperature standards by the state and their review by the US Environmental Protection Agency. It is a companion to other detailed reviews of the literature on thermal effects on organisms important to the region. Many factors, both natural and anthropogenic, affect water temperatures in the region. Different environmental zones have characteristic temperatures and mechanisms that affect them. There are specific biotic adaptations to environmental temperatures. Life-cycle strategies of salmonids, in particular, are attuned to annual temperature patterns. Physiological and behavioral requirements on key species form the basis of present water temperature criteria, but may need to be augmented with more concern for environmental settings. There are many issues in the setting of standards, and these are discussed. There are also issues in compliance. Alternative temperature-regulating mechanisms are discussed, as are examples of actions to control water temperatures in the environment. Standards-setting is a social process for which this report should provide background and outline options, alternatives, limitations, and other points for discussion by those in the region.

Physical Mechanisms for the Maintenance of GCM-Simulated Madden-Julian Oscillation over the Indian Ocean and Pacific  

SciTech Connect

The kinetic energy budget is conducted to analyze the physical processes responsible for the improved Madden-Julian Oscillation (MJO) simulated by the Iowa State University general circulation models (ISUGCM). The modified deep convection scheme that includes the revised convection closure, convection trigger condition and convective momentum transport (CMT) enhances the equatorial (10oS-10oN) MJO-related perturbation kinetic energy (PKE) in the upper troposphere and leads to more robust and coherent eastward propagating MJO signal. In the MJO source region-the Indian Ocean (45oE-120oE), the upper-tropospheric MJO PKE is maintained by the vertical convergence of wave energy flux and the barotropic conversion through the horizontal shear of mean flow. In the convectively active region-the western Pacific (120oE-180o), the upper-tropospheric MJO PKE is supported by the convergence of horizontal and vertical wave energy fluxes. Over the central-eastern Pacific (180o-120oW), where convection is suppressed, the upper-tropospheric MJO PKE is mainly due to the horizontal convergence of wave energy flux. The deep convection trigger condition produces stronger convective heating which enhances the perturbation available potential energy (PAPE) production and the upward wave energy fluxes, and leads to the increased MJO PKE over the Indian Ocean and western Pacific. The trigger condition also enhances the MJO PKE over the central-eastern Pacific through the increased convergence of meridional wave energy flux from the subtropical latitudes of both hemispheres. The revised convection closure affects the response of mean zonal wind shear to the convective heating over the Indian Ocean and leads to the enhanced upper-tropospheric MJO PKE through the barotropic conversion. The stronger eastward wave energy flux due to the increase of convective heating over the Indian Ocean and western Pacific by the revised closure is favorable to the eastward propagation of MJO and the convergence of horizontal wave energy flux over the central-eastern Pacific. The convection-induced momentum tendency tends to decelerate the upper-tropospheric wind which results in a negative work to the PKE budget in the upper troposphere. However, the convection momentum tendency accelerates the westerly wind below 800 hPa over the western Pacific, which is partially responsible for the improved MJO simulation.

Hydroxylated and methylsulfonyl polychlorinated biphenyl metabolites in albatrosses from Midway Atoll, North Pacific Ocean  

SciTech Connect

Concentrations of hydroxylated metabolites of polychlorinated biphenyls (PCBs) (OH-PCBs) and methylsulfonyl metabolites of PCBs (MeSO{sub 2}-PCBs) were determined in plasma and liver of albatrosses collected from the Midway Atoll in the central North Pacific Ocean. The mean total concentrations of OH-PCBs in plasma of Laysan albatrosses (Diomedea immutabilis) and black-footed albatrosses (Diomedea nigripes) were 11.5 and 27.1 ng/g wet weight, respectively. Total concentrations of OH-PCBs were only one- to fivefold less than those of total PCBs. 4-hydroxy-2,2{prime},3,4{prime},5,5{prime},6-heptachlorinated biphenyl and 4-hydroxy-2,2{prime},3,4{prime},5,5{prime}-hexachlorinated biphenyl were the predominant polychlorinated biphenylols, constituting 70 to 90% of the total OH-PCBs. Concentrations of MeSO{sub 2}-PCBs in liver were between 10.6 and 77 ng/g, lipid weight, approximately 250 times less than those of total PCBs. The MeSO{sub 2}-PCBs congeners retained in the liver were dominated by those having the methylsulfonyl group in the 3-position.

Precise determination of dissolved platinum in seawater of the Japan Sea, Sea of Okhotsk and western North Pacific Ocean  

Science Journals Connector (OSTI)

Abstract Platinum is among the least abundant elements in the earth's crust and is now widely used in various products such as catalytic converters in automobiles and anticancer drugs. Consequently, the concentration of Pt in urban aquatic environments is increasing. However, little is known about the distributions and geochemical cycles of Pt in the ocean owing to its low concentrations in seawater (Pacific Ocean. For determining sub-picomolar levels of Pt in seawater, we used isotope-dilution ICP-MS (Inductively Coupled Plasma Mass Spectrometry) after column preconcentration with an anion exchange resin. This method facilitated highly accurate analysis of Pt in seawater using small sample volumes (~ 1 L). The detection limit and procedural blank value for this method were 0.015 and approximately 0.01 pmol/L, respectively. We obtained conservative vertical distributions, with nearly constant Pt concentrations between 0.19 and 0.25 pmol/L in the Japan Sea, Sea of Okhotsk, and western North Pacific Ocean. Judging from the constant dissolved Pt profiles, little anthropogenic influence of Pt is apparent in the open oceans at the present time.

SciTech Connect

This data documentation discusses the procedures and methods used to obtain total carbon dioxide (TCO{sub 2}), total alkalinity (TALK), hydrographic, and chemical data during the Research Vessel Thomas Washington Expedition TUNES-3 in the Equatorial Pacific Ocean (Section P16C). Conducted as a part of the World Ocean Circulation Experiment (WOCE), the cruise began in Papeete, Tahiti, on August 31, 1991, and finished in Honolulu, Hawaii, on October 1, 1991. WOCE Meridional Section P16C along 150{degree}W and between 18{degree}S and 19{degree}N was completed during the 31-day expedition. All 105 hydrographic and 8 large-volume stations were completed to the full water column depth. Station spacing was 30 nautical miles (nm), except between 3{degree}N and 3{degree}S where it was 10 nm. Twenty-five bio-optics stations were sampled for the Joint Global Ocean Flux Study, and at 21 stations carbon dioxide measurements were provided for the US Department of Energy`s CO{sub 2} program. Hydrographic and chemical measurements made along WOCE Section P16C included pressure, temperature, salinity, and oxygen measured by conductivity, temperature, and depth sensor; and bottle salinity, oxygen, phosphate, nitrate, nitrite, silicate, chlorofluorocarbon (CFC)-11, CFC-12, TCO{sub 2}, and TALK. In addition, potential temperatures were calculated from the measured variables.

Distribution of glycerol ether lipids in the oxygen minimum zone of the Eastern Tropical North Pacific Ocean  

Science Journals Connector (OSTI)

Abstract The distributions of microbial glycerol ether lipids in suspended particulate matter in the oxygen minimum zone (OMZ) of the Eastern Tropical North Pacific Ocean (ETNP) were investigated. Nine groups of glycerol ether core lipids were detected and quantified: isoprenoid glycerol dialkyl glycerol tetraethers (GDGTs) (iso-GDGTs), isoprenoid glycerol dialkanol diethers (iso-GDDs) and hydroxylated isoprenoid \\{GDGTs\\} and \\{GDDs\\} (OH-GDGTs and OH-GDDs) of archaeal origin; branched glycerol dialkyl glycerol tetraethers (br-GDGTs) of bacterial origin and overly branched \\{GDGTs\\} (OB-GDGTs), sparsely branched \\{GDGTs\\} (SB-GDGTs), hybrid isoprenoid/branched \\{GDGTs\\} (IB-GDGTs) and a tentatively assigned H-shaped GDGT (H-1020) of unknown biological origin. The archaeal iso-GDGTs were the most abundant core lipids (89% of total), followed by iso-GDDs (4%), br-GDGTs (2%) and OH-GDGTs (1%). Archaeal intact polar \\{GDGTs\\} (IP GDGTs), including both mono- and diglycosidic iso-GDGTs, had depth profiles similar to OH-GDGTs and OH-GDDs, with a maximum concentration in the upper OMZ and secondary peaks in the mid and lower OMZ, suggesting similar but multiple planktonic sources. Core lipids of iso-GDGTs and other glycerol ethers showed deviating concentration profiles compared with IP \\{GDGTs\\} and OH-GDGTs and were most abundant in the mid OMZ. This is the first report of OH-GDDs, OB-GDGTs, SB-GDGTs, IB-GDGTs and H-1020 in the marine water column and the distribution patterns of these “orphan lipids” suggest that anaerobic planktonic microbes are their main source.

MEASUREMENTS OF PAST 14C LEVELS AND 13C/12C RATIOS IN THE SURFACE WATERS OF THE WORLD'S SUBPOLAR OCEANS.  

SciTech Connect

Under this project we have developed methods that allow the reconstruction of past {sup 14}C levels of the surface waters of the subpolar North Pacific Ocean by measuring the {sup 14}C contents of archived salmon scales. The overall goal of this research was to reduce of the uncertainty in the uptake of fossil CO{sub 2} by the oceans and thereby improve the quantification of the global carbon cycle and to elucidate the fate of anthropogenic CO{sub 2}. Ocean General Circulation Models (OGCMs), with their three dimensional global spatial coverage and temporal modeling capabilities, provide the best route to accurately calculating the total uptake of CO{sub 2} by the oceans and, hence, to achieving the desired reduction in uncertainty. {sup 14}C has played, and continues to play, a central role in the validation of the OGCMs calculations, particularly with respect to those model components which govern the uptake of CO{sub 2} from the atmosphere and the transport of this carbon within the oceans. Under this project, we have developed time-series records of the {sup 14}C levels of the surface waters of three areas of the subpolar North Pacific Ocean. As the previously available data on the time-history of oceanic surface water {sup 14}C levels are very limited, these time-series records provide significant new {sup 14}C data to constrain and validate the OGCMs.

Power Europe: EU and the illegal, unreported and unregulated tuna fisheries regulation in the West and Central Pacific Ocean  

Science Journals Connector (OSTI)

Abstract Illegal, unreported and unregulated (IUU) fishing activities are widely considered a main cause of unsustainable fisheries across the globe. The EU has taken a leading role in the fight against IUU fishing, using both its market and normative power to advance its EU IUU Regulation (no. 1005/2008) and wider fisheries sustainability agenda outside its territory. This paper examines how successful the EU has been in using its market and normative power to influence regulatory strategies and frameworks governing tuna fisheries in the Pacific Islands region of the Western Pacific Ocean. The results indicate that while the market power of the EU remains an influential factor, the diminishing normative power of the EU in WCPO is weakening any attempts to implement its IUU fishing regulation and Pacific Island nations have promoted their own regulatory agenda. We conclude that the changing asymmetries between market and normative power has led to a differentiated geography of regulatory uptake, and while market power will remain a dominant strategy for the EU, normative power, when exercised should focus on cooperation rather than ‘teaching’ the benefits of an EU regulatory approach.

As a collaborative program to measure global ocean carbon inventories and provide estimates of the anthropogenic carbon dioxide (C02) uptake by the oceans. the National Oceanic and Atmospheric Administration and the U.S. Department of Energy have sponsored the collection of ocean carbon measurements as part of the World Ocean Circulation Experiment and Ocean-Atmosphere Carbon Exchange Study cruises. The cruises discussed here occurred in the North and South Pacific from 1990 through 1996. The carbon parameters from these 30 crossover locations have been compared to ensure that a consistent global data set emerges from the survey cruises. !'he results indicate that for dissolved inorganic carbon. fugacity of C02• and pH. the a~:,rreements at most crossover locations are well within the design specifications for the global CO) survey: whereas. in the case of total alkaliniry. the agreement between crossover locations is not as close.

A compilation of nuclear weapons test detonation data for U.S. Pacific ocean tests  

SciTech Connect

Prior to December 1993, the explosive yields of 44 of 66 nuclear tests conducted by the United States in the Marshall Islands were still classified. Following a request from the Government of the Republic of the Marshall Islands to the U.S. Department of Energy to release this information, the Secretary of Energy declassified and released to the public the explosive yields of the Pacific nuclear tests. This paper presents a synopsis of information on nuclear test detonations in the Marshall Islands and other locations in the mid-Pacific including dates, explosive yields, locations, weapon placement, and summary statistics. 10 refs., 1 fig., 2 tabs.

Oceanic CO{sub 2} measurements for the WOCE hydrographic survey in the Pacific Ocean, 1990--1991: Shore based analyses. Technical data report  

SciTech Connect

The Office of Health and Environmental Research, of the US Department of Energy (DOE), actively supports global survey investigations of carbon dioxide in the oceans. This large scale study is in conjunction with the hydrographic program of the World Ocean Circulation Experiment (WOCE/HP). On ocean cruises operated by WOCE/HP, carbon dioxide analysis groups, from various oceanographic institutions, perform shipboard chemical measurements of the inorganic carbon system in the ocean. Measurements of total dissolved inorganic carbon (DIC) are of central importance to this carbon survey. Shipboard measurements of DIC were made by employing a coulometric technique. The majority of coulometric measurements were made on an integrated automatic device, the Single Operator Multi-Parameter Metabolic Analyzer (SOMMA). In addition to DIC determinations, shipboard analytical groups measured at least one additional parameter of sea water carbon chemistry. This was done to more fully characterize the inorganic carbon system of the sea water sample. This thechnical data report presents DIC and ALK measurements performed in the SIO laboratory on replicate samples collected on the five expedition legs of the WOCE/HP cruises.

SciTech Connect

This report represents a synthesis and reformatting of six primary documents and other related materials on soils, ocean sediments, air, and biota investigations conducted at Johnston Island (JI), Pacific Ocean, to characterize contamination resulting from storage of 1.37 million gallons of Herbicide Orange (HO) from 1972 through 1977. The individual study components comprise the Remedial Investigation (RI) of the former HO storage site at JI. This report describes the procedures, results, and conclusions of the sampling and analysis programs conducted at JI. Samples of site soils, ocean sediments, airborne particulates, dust, sweepings, and aquatic organisms were collected and analyzed for HO-derived 2,4-dichlorophenoxyacetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), and 2,3,7,8- tetrachlorodibenzo-p-dioxin (TCDD). Environmental media other than soils at the storage facility itself were found to be free of contamination or to contain very low contaminant concentrations. No contamination was found in ocean sediments, indicating possible dispersion of contaminants due to erosion. A few of the biological specimens collected were found to contain TCDD levels below the guidelines of 25 to 50 parts per trillion established by the US Food and Drug Administration; TCDD in all other biota samples was nondetectable. Analysis of samples of airborne particulates and of soils, dust, and sweepings from high-use and residential areas outside the boundaries of the former storage site indicated that there is little or no concern of adverse impacts from airborne transport and deposition of TCDD.

Attenuation of low?frequency sound in the Northeast Pacific Ocean  

Science Journals Connector (OSTI)

Long?range propagation losses were measured at frequencies from 0.025 to 0.8 kHz to the north and south of a receiver at 46?°N 143°30?W in the Northeast Pacific. To the south of the station the attenuation losses experienced a pronounced minimum near 50 Hz and approached the one?half Thorp value at 0.8 kHz. An examination of the behavior of the attenuation coefficient as a function of range indicated that a range of at least 700 km would be required to make meaningful measurements of attenuation in this area. To the north of the receiving station focusing of the sound due to a rapidly shallowing sound channel prevented reliable measurement of the attenuation coefficient at any range.

Comparison of reduced-order, sequential and variational data assimilation methods in the tropical Pacific Ocean  

E-Print Network (OSTI)

This paper presents a comparison of two reduced-order, sequential and variational data assimilation methods: the SEEK filter and the R-4D-Var. A hybridization of the two, combining the variational framework and the sequential evolution of covariance matrices, is also preliminarily investigated and assessed in the same experimental conditions. The comparison is performed using the twin-experiment approach on a model of the Tropical Pacific domain. The assimilated data are simulated temperature profiles at the locations of the TAO/TRITON array moorings. It is shown that, in a quasi-linear regime, both methods produce similarly good results. However the hybrid approach provides slightly better results and thus appears as potentially fruitful. In a more non-linear regime, when Tropical Instability Waves develop, the global nature of the variational approach helps control model dynamics better than the sequential approach of the SEEK filter. This aspect is probably enhanced by the context of the experiments in tha...

Acoustic identification of nine delphinid species in the eastern tropical Pacific Ocean  

Science Journals Connector (OSTI)

Acoustic techniques have the potential to increase the reliability of cetacean species identification during shipboard surveys. The whistles of nine odontocete species were compared using data collected from a towed array and sonobuoys deployed during dolphin abundance surveys in the eastern tropical Pacific. Twelve variables were measured manually from spectrographic displays of each whistle (n=912). Multivariate discriminant function analysis (DFA) resulted in 49.9% of whistles being classified to the correct species. It was hypothesized that some whistles carry less species?specific information than others therefore groups of five whistles were averaged to reduce the effect of these ambiguous whistles. Correct classification increased to 65.4% when DFA was run on the averaged data set. A species identification decision tree that used 7 of the 12 whistle variables was constructed using nonparametric techniques (classification and regression trees) and resulted in 53.1% correct classification when applied to the original data set. Prior probabilities were added to the decision tree based on sighting rates for each species in the study area resulting in 56.7% correct classification. The species identification decision tree provides a relatively simple acoustic method that can be used to augment conventional visual techniques.

Golfingicola abyssalis gen. et sp. nov., a new endoparasitic copepod (Crustacea) in a sipunculan from abyssal depths of the Northwest Pacific Ocean  

Science Journals Connector (OSTI)

Abstract Marine copepods, which inhabit the entire water column down to the seafloor, are key contributors to the food web, mainly providing a food source for many organisms in the form of zooplankton. Furthermore, they also play an important ecological role as associates or even parasites with various degrees of harm to their hosts. Copepods are found in almost all habitats and can be associated with virtually every metazoan group. A female and four males of a new endoparasitic copepod genus and species (Golfingicola abyssalis) are described from the trunk celom of the sipunculan Golfingia muricaudata (Southern, 1913), collected from the abyssal depths of the Northwest Pacific Ocean near the Kuril–Kamchatka Trench. This sipunculan species is a typical deep sea representative of the northwestern Pacific region, occurring in the Bering Sea and the abyssal regions east of the Kuril Island chain. Despite numerous records of this species, a copepod association has not been reported prior to this paper. The new parasitic copepod species is tentatively placed in the Akessonia group given its endoparasitic behavior in Sipuncula, the elongated shape, the enlarged egg strings, and the presence of subchelate antenna, as well as lateral processes in males. Golfingicola abyssalis, however, shows some peculiarities that clearly differentiate it from the remaining endoparasites in Sipuncula. As the first abyssal endoparasite in Sipuncula, the species is characterized by the complete lack of any processes in females, the presence of a mandible in females, a weakly defined prosome–urosome boundary in females, the presence of a mouth in males, the free living behavior of males, a distinctly reduced number of trunk processes in males, as well as a more modified male antenna, displaying an endopodite and a highly modified setal element. A detailed review on the morphological characters of the four species currently grouped in the Akessonia group, and systematic and biogeographic information of their relevant host taxa is provided. On the basis of morphological and ecological similarities, the new species seems to be more closely related to the northern Atlantic Akessonia occulta Bresciani and Luetzen, 1962 than to Siphonobius gephyreicola Augener, 1903 and Coelotrophus nudus Ho et al., 1981.

Geospatial analysis of oil discharges observed by the National Aerial Surveillance Program in the Canadian Pacific Ocean  

Science Journals Connector (OSTI)

Abstract Oil pollution resulting from day to day human maritime activities contributes a high portion of the overall input into marine environments, constituting a major threat to marine ecosystems worldwide. In Canada, the National Aerial Surveillance Program (NASP) extensively monitors and collects information on oily discharges using remote sensing devices. Despite the availability of data from NASP and other surveillance programs internationally, there is a paucity of spatial analyses of oil pollution patterns, particularly in their association with human marine pursuits. The objective of this paper is to analyze the association between observed oily discharges and human maritime activities in the Canadian Pacific Ocean. This study used Poisson regression to spatially model detected oily discharges with marine traffic, coastal facilities and proximity to coast. Further, it developed localized (‘regional’) models to address spatial heterogeneity. The models identify recreational activities, passenger traffic, commercial traffic, fisheries, and proximity to the coast as predictors of observed oily discharges. The regional models yield more accurate and reliable estimates of local associations, and identify more parsimonious sets of predictors for each region. By identifying and accounting for human activities most associated with oily discharge patterns, the models developed in this study could be used to estimate pollution rates in areas with less surveillance, and identify areas where NASP coverage may need to be increased. Spatially explicit rates estimated by these models can be used to monitor the effectiveness of programs and policy aimed at reducing discharge rates of oily pollution. This study can be used as a model approach for extending the analysis to the other coasts of Canada, using available NASP data.

Accumulation and toxicity assessment of polychlorinated biphenyls in black-footed albatross (Diomedea nigripes) from Midway Atoll, North Pacific Ocean  

Science Journals Connector (OSTI)

Polychlorinated biphenyls (PCBs) are ubiquitous chemicals that were used as additives in capacitors and transformers; and heavy contamination in the past of Midway Atoll, a national wildlife refuge, puts the wildlife, including the black-footed albatross (BFAL), at risk. In this study, we assess the profiles and toxicity of the individual PCB congeners at a natural equilibrium state in various tissues of 1-month old and 4–5-month old BFAL chicks and black-footed and Laysan albatross eggs found on the atoll. In the 1-month old chicks from Midway Atoll, the major seven congeners \\{PCBs\\} 99, 118, 138, 153, 170, 180 and 183 accounted for 36–78% of the total \\{PCBs\\} in the various body parts, and the total PCB concentrations in the bird samples are inversely related to the total body weights. In the 4–5-month old chicks, these same congeners accounted for much lower percentages (7–26%) than in the 1-month-old chicks, with higher amounts of the less chlorinated congeners. The total toxic equivalents (TEQs) for all of the tissues in the 1-month old chicks ranged from 130 to 11,000 pg g?1 (lipid weight, lw), and the total \\{TEQs\\} for the 4–5-month old chicks ranged from 18,000 to 100,000 pg g?1. The average total concentration was 7.9 and 4.6 ?g g?1 lw in the BFAL eggs and Laysan albatross eggs, respectively. The high concentrations could be accounted for by the age and PCB accumulation of the female producing the egg. The average \\{TEQs\\} were 70 and 90 pg g?1 in the Laysan albatross eggs and BFAL eggs, respectively. This PCB concentration and toxicity information can be used to determine the toxicological risk of the BFAL chicks while nesting at Midway Atoll, and the analysis of the albatross eggs is an indication of the contamination of the female albatross at the time of egg formation, with the levels acting as an indicator of the total PCB body burdens that the females are experiencing. The information from this study is indicative of the toxicological risk to the seabirds that nest and feed near Midway and of the overall PCB contamination in the North Pacific Ocean.

Metal levels in feathers of 12 species of seabirds from Midway Atoll in the northern Pacific Ocean  

Science Journals Connector (OSTI)

Seabirds are excellent subjects for examination of heavy metals because they are long-lived, feed at different distances from land, and exhibit different trophic levels. In this paper we compare the levels of lead, cadmium, mercury arsenic, chromium, manganese, selenium, and tin in the feathers of birds nesting on Midway Atoll in the northern Pacific Ocean. We test the null hypothesis that there are no interspecific differences in the levels of metals in the feathers of the adult black-footed albatross (Diomedea nigripes), Laysan albatross (Diomedea immutabilis), red-footed booby (Sula sula), great frigatebird (Fregata minor), Bonin petrel (Pterodroma hypoleuca), Christmas shearwater (Puffinus nativitatis), red-tailed tropicbird (Phaethon rubricauda), wedge-tailed shearwater (Puffinus pacificus), brown noddy (Anous stolidus), sooty tern (Sterna fuscata), grey-backed tern (Sterna lunata), and white tern (Gygis alba), and young of some of these species. There were interspecific differences in the levels of all metals for adults. Christmas shearwater had the highest levels of lead, cadmium, selenium and manganese, but the second lowest levels of mercury. In general, metal levels were the lowest in the smallest species (white tern), but were not the highest in the largest species (black-footed albatross), except for manganese, arsenic and mercury. There was a high variance in metal levels among adults for some species, but not for others. White tern adults were variable for lead, while Christmas shearwaters were variable for lead and cadmium. Compared to the means for metals in other birds generally (after Burger, 1993), Christmas shearwaters had higher levels of lead, white terns, brown noddy, Christmas shearwater, frigatebirds and Laysan albatrosses had higher levels of cadmium, and bonin petrel, wedge-tailed shearwater, tropicbirds, frigatebirds, red-footed boobies, and both albatrosses had higher levels of mercury. Whereas the means for lead and cadmium were below the known effects levels, some individuals had levels high enough to cause adverse effects in the birds. The mean values for mercury in Bonin petrel, red-tailed tropicbird, and black-footed albatross were higher than the levels known to cause adverse reproductive and behavioral effects.

A critical evaluation of the upper ocean heat budget in the Climate Forecast System Reanalysis data for the south central equatorial Pacific  

SciTech Connect

Coupled ocean-atmospheric models suffer from the common bias of a spurious rain belt south of the central equatorial Pacific throughout the year. Observational constraints on key processes responsible for this bias are scarce. The recently available reanalysis from a coupled model system for the National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) data is a potential benchmark for climate models in this region. Its suitability for model evaluation and validation, however, needs to be established. This paper examines the mixed layer heat budget and the ocean surface currents - key factors for the sea surface temperature control in the double Inter-Tropical Convergence Zone in the central Pacific - from 5{sup o}S to 10{sup o}S and 170{sup o}E to 150{sup o}W. Two independent approaches are used. The first approach is through comparison of CFSR data with collocated station observations from field experiments; the second is through the residual analysis of the heat budget of the mixed layer. We show that the CFSR overestimates the net surface flux in this region by 23 W m{sup -2}. The overestimated net surface flux is mainly due to an even larger overestimation of shortwave radiation by 44 W m{sup -2}, which is compensated by a surface latent heat flux overestimated by 14 W m{sup -2}. However, the quality of surface currents and the associated oceanic heat transport in CFSR are not compromised by the surface flux biases, and they agree with the best available estimates. The uncertainties of the observational data from field experiments are also briefly discussed in the present study.

Reconstruction of drought variability in North China and its association with sea surface temperature in the joining area of Asia and Indian–Pacific Ocean  

Science Journals Connector (OSTI)

Abstract Using tree-ring data from the northernmost marginal area of the East Asian summer monsoon (EASM) in North China, May–July mean Palmer drought severity index (PDSI) was reconstructed back to 1767 AD. The reconstruction captured 52.8% of the variance over the calibration period from 1945 to 2005 AD and showed pronounced pluvial periods during 1850–1905, 1803–1811 and 1940–1961 and dry periods during 1814–1844, 1916–1932 and 1984–2012. These anomalous periods have previously been reported in other parts of North China. Spatial correlation analyses and comparisons with other hydroclimatic indices in North China indicated that our new PDSI reconstruction could represent spatial and temporal drought variability in this region well. Our work also suggested that the drying tendency currently observed in the northern part of North China (including the study area) is consistent with the weakening of the EASM. Meanwhile the drying trend was seemingly restrained at present in the southern part of North China. Spatial correlation patterns with global sea surface temperature (SST) indicated that the regional hydroclimatic variability in North China was tightly linked to SST over the joining area of Asia and Indian–Pacific Ocean (AIPO), especially over the tropical western Pacific. When SST from prior November to current July (NJ-SST) in the AIPO area was anomalously high (low), the thermal contrast between Asian land and ocean was weakened (strengthened), and the EASM was correspondingly weakened (strengthened), thereby causing droughts (pluvials) in North China. The results of this study do not only provide useful information for assessing the long-term climate change in North China, but also suggest that abnormal variability in NJ-SST over the AIPO area could be used to forecast hydroclimatic conditions in North China.

The persistence of oceans on Earth-like planets: insights from the deep-water cycle  

E-Print Network (OSTI)

In this paper we present a series of models for the deep water cycle on super-Earths experiencing plate tectonics. The deep water cycle can be modeled through parameterized convection models coupled with a volatile recycling model. The convection of the silicate mantle is linked to the volatile cycle through the water-dependent viscosity. Important differences in surface water content are found for different parameterizations of convection. Surface oceans are smaller and more persistent for single layer convection, rather than convection by boundary layer instability. Smaller planets have initially larger oceans but also return that water to the mantle more rapidly than larger planets. Super-Earths may therefore be less habitable in their early years than smaller planets, but their habitability (assuming stable surface conditions), will persist much longer.

Multi-scale modeling of Puget Sound using an unstructured-grid coastal ocean model: from tide flats to estuaries and coastal waters  

SciTech Connect

Water circulation in Puget Sound, a large complex estuary system in the Pacific Northwest coastal ocean of the United States, is governed by multiple spatially and temporally varying forcings from tides, atmosphere (wind, heating/cooling, precipitation/evaporation, pressure), and river inflows. In addition, the hydrodynamic response is affected strongly by geomorphic features, such as fjord-like bathymetry and complex shoreline features, resulting in many distinguishing characteristics in its main and sub-basins. To better understand the details of circulation features in Puget Sound and to assist with proposed nearshore restoration actions for improving water quality and the ecological health of Puget Sound, a high-resolution (around 50 m in estuaries and tide flats) hydrodynamic model for the entire Puget Sound was needed. Here, a threedimensional circulation model of Puget Sound using an unstructured-grid finite volume coastal ocean model is presented. The model was constructed with sufficient resolution in the nearshore region to address the complex coastline, multi-tidal channels, and tide flats. Model open boundaries were extended to the entrance of the Strait of Juan de Fuca and the northern end of the Strait of Georgia to account for the influences of ocean water intrusion from the Strait of Juan de Fuca and the Fraser River plume from the Strait of Georgia, respectively. Comparisons of model results, observed data, and associated error statistics for tidal elevation, velocity, temperature, and salinity indicate that the model is capable of simulating the general circulation patterns on the scale of a large estuarine system as well as detailed hydrodynamics in the nearshore tide flats. Tidal characteristics, temperature/salinity stratification, mean circulation, and river plumes in estuaries with tide flats are discussed.

Behavior of skipjack tuna (Katsuwonus pelamis) associated with a drifting FAD monitored with ultrasonic transmitters in the equatorial central Pacific Ocean  

Science Journals Connector (OSTI)

Abstract The behavior of skipjack tuna Katsuwonus pelamis released at a drifting fish aggregating device (FAD) in the equatorial central Pacific Ocean was investigated using ultrasonic transmitters. We conducted two types of field observations: one to track a single fish using a continuous transmitter, and the other to simultaneously monitor multiple individuals with coded transmitters. In the first examination, the behavior of one individual (fork length (FL) of 65.2 cm) was monitored when the fish was both near and away from the FAD. In the second examination, the behaviors of 14 individuals (FL between 36.0 and 64.0 cm) were monitored only when these were associated with the FAD. The behaviors of the fish were monitored 82.0 and 154.5 h using continuous and coded transmitters, respectively. The fish monitored with a continuous transmitter made several excursions from the FAD (maximum distance of approximately 9700 m) during the monitoring period. The swimming depth during daytime was deeper than that observed during nighttime, and this difference was markedly more obvious when the fish was away from the FAD. Additionally, the daytime swimming depth was deeper when the fish was away from the FAD. The swimming speed of the fish monitored with a continuous transmitter was usually less than 3 KT and was higher during daytime compared with nighttime. The fish monitored with coded transmitters occasionally left the FAD, particularly during nighttime, partly demonstrated diurnal vertical movements, and were mainly distributed in the mixed layer or upper part of the thermocline. In addition, the results showed a synchronicity in the vertical movements of two or more fish. This study indicated a clear difference between the on-FAD and the off-FAD vertical movements, occasional excursions from the FAD, and diurnal movements of the fish, especially when away from the FAD.

Carbon dioxide, hydrographic, and chemical data obtained in the Central South Pacific Ocean (WOCE sections P17S and P16S) during the tunes-2-expedition of the R/V Thomas Washington, July--August 1991  

SciTech Connect

This data documentation discusses the procedures and methods used to measure total carbon dioxide (TCO{sub 2}), discrete partial pressure of TCO{sub 2} (pCO{sub 2}), and total alkalinity (TALK), during the Research Vessel (R/V) Thomas Washington TUNES Leg 2 Expedition in the central South Pacific Ocean. Conducted as part of the World Ocean Circulation Experiment (WOCE), the cruise began in Papeete, Tahiti, French Polynesia, on July 16, 1991, and returned to Papeete on August 25, 1991. WOCE Meridional Sections P17S along 135{degrees} W and P16S along 150{degrees} W were completed during the 40-day expedition. A total of 97 hydrographic stations were occupied. Hydrographic and chemical measurements made along WOCE Sections P17S and P16S included pressure, temperature, salinity, and oxygen measured by conductivity, temperature and depth sensor; bottle salinity; oxygen; phosphate; nitrate; nitrite; silicate; CFC-12; CFC- 11; TCO{sub 2}; TALK; and pCO{sub 2} measured at 20{degrees}C. The TCO{sub 2} concentration in 1000 seawater samples was determined with a coulometric analysis system, the pCO{sub 2} in 940 water samples was determined with an equilibrator/gas chromatograph system, while the TALK concentration in 139 samples was determined on shore at the laboratory of C. Goyet of Woods Hole Oceanographic Institution with an alkalinity titration system. In addition, 156 coulometric measurements for the Certified Reference Material (Batch {number_sign}6) were made and yielded a mean value of 2303.2 {plus_minus} 1.5 {mu}mol/kg. This mean value agrees within a standard deviation of the 2304.6 {plus_minus} 1.6 {mu}mol/kg (N=9) value determined with the manometer of C. D. Keeling at Scripps Institution of Oceanography (SIO). Replicate samples from 11 Niskin bottles at 4 stations were also collected for later shore-based reference analyses of TCO{sub 2} and TALK by vacuum extraction and manometry in the laboratory of C. D. Keeling of SIO.

Tier 1 ecological evaluation of proposed discharge of dredged material from Oakland Harbor into ocean waters  

SciTech Connect

The Water Resources Development Act of 1986 (Public Law 99--662) authorized the U.S. Army Corps of Engineers (USACE) -- San Francisco District, to accommodate larger, deeper draft vessels in Oakland inner and Outer Harbors by deepening and widening the existing navigation channel, and providing turning basins and maneuvering areas in Oakland inner Harbor. The suitability of the resulting dredged material for disposal into ocean waters was subject to the procedures of the 1991 Testing Manual, Evaluation of Dredged Material Proposed for Ocean Disposal, known as the ``Green Book``. The Green Book provides a tiered approach for testing the suitability of dredged materials through chemical, physical, and biological evaluations. The first level of investigation, or Tier 1 evaluation, is used to determine whether a decision on LPC compliance can be made on the basis of readily available information. The Tier 1 report primarily summarizes existing information on sediment contamination and toxicity potential, identifies contaminants of concern, and determines the need for further testing. To assist the USACE in determining the suitability of dredged material from Oakland inner and Outer Harbors for ocean disposal, Battelle/Marine Sciences Laboratory prepared this Tier 1 report based upon information and data provided by USACE. Because this Tier 1 report originated well after an LPC determination was made to require testing of project sediments in Tier 3, the primary purpose of this report was to identify contaminants of concern (if any) in that particular dredged material. In addition, this Tier 1 report summarizes available information on chemical, physical, and biological characterization of the sediments in Oakland inner and Outer Harbors.

Modelling the Effect of Ocean Waves on the Atmospheric and Ocean Boundary Layers  

Science Journals Connector (OSTI)

Ocean waves, in addition to generating direct forces on fixed and floating offshore wind generator structures, also have significant indirect effects via their influence on the atmospheric and oceanic boundary layers above and below the water surface. In the atmospheric boundary layer the waves act as roughness elements, influencing the turbulent flow and the vertical wind speed profile, and induce oscillatory motions in the airflow. Spray droplets from breaking wave crests enhance structure corrosion, and may lead to icing under low-temperature conditions. Below the water surface, the air-sea momentum flux and mechanical energy flux, mediated by the waves and wave-generated turbulence, affect the vertical profiles of ocean current, temperature, and salinity. Effects include modifying the structural forces and dynamics, and the movement and dispersion of marine organisms, pollutants, and air bubbles generated by breaking waves, with consequences for fouling, corrosion, and environmental impact. Measurement of relevant airflow and ocean dynamical variables is also challenging, as near the water surface it is often necessary to use instruments mounted on moving measurement platforms. Modelling such boundary-layer effects is a complex task, as a result of feedbacks between the airflow, wave field, current field, and turbulence in the atmosphere and the ocean. We present results from a coupled model study of the North Sea and Norwegian Sea area. We employ a mesoscale atmosphere model (WRF) and a spectral wave model (WAM), running simultaneously and coupled using the open-source coupler MCEL which can interpolate between different model grids and time steps. To investigate the ocean boundary layer, one-dimensional model experiments were performed for an idealized Ekman layer and for locations in the North Sea, Atlantic Ocean, and the northern Pacific, using a version of the GOTM turbulence model, modified to take wave dynamics into account. Results show how the wave field alters the ocean's aerodynamic roughness and the air–sea momentum flux, depending on the relation between the surface wind speed and the propagation speed of the wave crests (the wave age). These effects will feed back into the airflow, wind speed and turbulence profile in the boundary layer. The ocean dynamics experiments showed results which compare favourably with field observations from the LOTUS3 and PROVESS experiments in the north Atlantic and North Sea, and Ocean Weather Station Papa in the Pacific Ocean.

Ecological evaluation of proposed discharge of dredged material from Oakland Harbor into ocean waters (Phase 3 A of -42-foot project)  

SciTech Connect

The Battelle/Marine Sciences Laboratory (MSL) conducted a study to determine whether dredged sediments from Oakland Inner and Outer Harbors were suitable for ocean disposal. Nineteen test treatments, six reference treatments, and three control treatments were tested for physical/chemical parameters, water column effects, dredged- sediment toxicity, and bioaccumulation potential. Physical/chemical parameters were analyzed at each site and each composite sediment to a depth of -44 ft MLLW. These parameters included analysis for geological characteristics, conventional sediment measurements (grain size, total volatile solids, total organic carbon, oil and grease, and total petroleum hydrocarbons), metals,, polynuclear aromatic hydrocarbons (PAHs), pesticides, butyltins, and polychlorinated biphenyls (PCBs). Physical/chemical data were used in support of the toxicological and bioaccumulation testing, but were not used in the decision-making criteria described in the Draft Implementation manual under Tier III testing. To evaluate water column effects, MSL conducted suspended-particulate-phase (SPP) test using the mysid shrimp Holmesimysis sculpta, speckled sanddab citharichtys stigmaeus, and larvae of the pacific oyster Crassostrea gigas. Both a 48-h and a 96-h test were performed. The MSL evaluated dredged-sediment toxicity by conducting a total of eight solid-phase toxicity tests using the following organisms: the bivalve clam Macoma nasuta, the polychaete worm Nepthys caecoides, the speckled sanddab C. stigmaeus, and the amphipod Rhepoxynius abronius. Test duration ranged from 10 to 28 days. Bioaccumulation potential was evaluated in the 28-day M. Nasuta and N. caecoides solid-phase exposures by measuring the contaminants of concern present in their tissues after exposure to test, reference, and control sediments. This report contains the data and test results.

Control of a fluid particle under simulated deep-ocean conditions in a high-pressure water tunnel  

Science Journals Connector (OSTI)

An apparatus that permits the observation of liquid C O 2 particles in a simulated deep-ocean environment was designed modeled constructed and tested. Analysis concerning the vertical stability and control of the fluid particle in a countercurrent flow loop is presented. The vertical position of the particle was found to vary due to the gradual dissolution of the C O 2 into the water and various other random effects. Using linearized equations for spherical particle motion in the fluid flow a second-order dynamic equation is derived and analyzed. The servocontrol system consists of a video system that digitizes particle position in a viewing window and a centrifugal pump that can control the speed of the countercurrent flow in order to maintain the particle within the observation window of a charge-coupled devicecamera. Currently the system is being used to obtain information on the dissolution behavior of C O 2 in seawater at various conditions of pressure and temperature that simulate ocean depths down to 3400 m . This information can be used to predict the fate of C O 2 drops in the ocean whether released from natural seeps leaks from suboceanic geologic C O 2 storage sites or from engineered deep-ocean injection systems. The study of other liquids and gases is also possible.

Cosmic Rays on the Pacific Ocean  

Science Journals Connector (OSTI)

Records of cosmic-ray intensity obtained on the R. M. S. Aorangi during 12 voyages between Vancouver, Canada and Sydney, Australia, from March 17, 1936, to January 18, 1937, using a Carnegie model C cosmic-ray meter, are described and discussed. Typical records exhibiting the latitude effect are shown. A summary of the data taken at sea is given in the form of graphs, in which each datum point represents the average of 6 hours readings with a probable statistical error of ±0.13 percent. Any variations due to a possible temperature coefficient of the instrument are negligible. The observed minimum of cosmic-ray intensity near the equator averages 10.3 percent less than the intensity at Vancouver, in satisfactory agreement, considering the difference in expermental conditions, with earlier measurements. The critical latitudes above which changes in intensity are less rapid, are found to be somewhat lower, 38.4°N and 34.2°S, than previously reported, and beyond these latitudes the intensity is found to continue to increase with latitude. At the higher latitudes is observed a variation, which appears to be seasonal, with the maximum in the cold months in both hemispheres. This variation is closely correlated with the atmospheric temperature. It is hence ascribed to changes in some atmospheric barrier of unknown nature, such as perhaps an atmospheric potential gradient, of whose strength the temperature of the atmosphere is an approximate but not exact index. Changes in this atmospheric barrier have been approximately allowed for by determining the external temperature coefficient and correcting the observations accordingly (this external temperature coefficient is comparable with that reported by Hess and his collaborators). The latitude effect curves as thus corrected should show the effect of the earth's magnetic field alone. They are now nearly flat beyond the critical latitudes and show a magnetic latitude effect of about 7.2 percent. This implies that a latitude effect of about 3.1 percent owes its origin to the atmospheric barrier. Seasonal variations in the corrected latitude effect curve are almost eliminated. Geomagnetic analysis of the energy distribution of the rays indicates a prominent component with a sharp energy threshold of about 7.5×109 ev, and a component so weak as to be questionable, whose energy threshold is not greater than 2.5×109 ev. It is not found possible to explain the 7.5×109 ev threshold in terms of atmospheric absorption as has previously been supposed. Two alternative interpretations are suggested. The difference in cosmic-ray intensity between the northern and southern hemispheres under comparable conditions, as calculated from these data in various ways, appears to be no larger than the probable error of about ±0.1 percent. This result is in conflict with the prediction by Compton and Getting of an excess in the north of about 0.5 percent, due to the motion of the earth with the rotation of the galaxy, but is not inconsistent with the small diurnal variation that has been found to follow sidereal time, if it is supposed that the cosmic rays acquire a part of the galactic motion.

Chapter 16 - Ocean Engines  

Science Journals Connector (OSTI)

Publisher Summary Ocean thermal energy converters (OTECs) took advantage of the ocean acting as an immense collector and storer of solar radiation, thus delivering a steady flow of low-grade thermal energy. The ocean plays a similar role in relation to the wind energy, which is transformed into waves far steadier than the air currents that created them. Nevertheless, waves are neither steady nor concentrated enough to constitute a highly attractive energy source notwithstanding their large total power. There is little net horizontal motion of water in a surface ocean wave. A floating object drifts in the direction of the wave with about 1% of the wave velocity. A given elementary cell of water will move in a vertical circle, surging forward near the crest of the wave but receding by an almost equal amount at the trough. Any system in which the wave velocity depends on wavelength is called dispersive; hence the deep ocean is dispersive.

A conceptual study of floating axis water current turbine for low-cost energy capturing from river, tide and ocean currents  

Science Journals Connector (OSTI)

The cost of utilizing kinetic energy of river stream, tidal and ocean current is considered to be higher than that of wind power generation because of difficulties in construction and maintenance of devices installed in seawater. As a solution to the problem, the authors propose a new concept of water stream turbine. The main idea is in the manner of supporting turbine. Although it is similar to a vertical axis turbine, the direction of turbine axis is not firmly fixed and its tilt angle is passively adjustable to the stream velocity. Since it does not have to keep the turbine axis in upright position, required structural strength and weight of the device will be reduced significantly. This paper describes the application ranging from the small hydro power in river streams to large application of tidal and ocean current turbine. In the large capacity plant for tidal stream and ocean current, the main mechanism of turbine axis support is the same as that of the wind turbine authors proposed in the previous paper. It leads to the further opportunity of cost reduction. The sample design of a multi-megawatt ocean current turbine shows the possibility of high economic performance of the concept. The results show that the cost of energy in the concept can be comparable to a land based wind turbine.

Flexible ocean upwelling pipe  

DOE Patents (OSTI)

In an ocean thermal energy conversion facility, a cold water riser pipe is releasably supported at its upper end by the hull of the floating facility. The pipe is substantially vertical and has its lower end far below the hull above the ocean floor. The pipe is defined essentially entirely of a material which has a modulus of elasticity substantially less than that of steel, e.g., high density polyethylene, so that the pipe is flexible and compliant to rather than resistant to applied bending moments. The position of the lower end of the pipe relative to the hull is stabilized by a weight suspended below the lower end of the pipe on a flexible line. The pipe, apart from the weight, is positively buoyant. If support of the upper end of the pipe is released, the pipe sinks to the ocean floor, but is not damaged as the length of the line between the pipe and the weight is sufficient to allow the buoyant pipe to come to a stop within the line length after the weight contacts the ocean floor, and thereafter to float submerged above the ocean floor while moored to the ocean floor by the weight. The upper end of the pipe, while supported by the hull, communicates to a sump in the hull in which the water level is maintained below the ambient water level. The sump volume is sufficient to keep the pipe full during heaving of the hull, thereby preventing collapse of the pipe.

Could ocean currents be responsible for the west to east spread of aquatic invasive species in Maritime Canadian waters?  

Science Journals Connector (OSTI)

Abstract The circulation in the shelf seas of Maritime Canada is predominantly in the northeast–southwest direction. Despite the mean northeast–southwest flow, a number of AIS invasions have been observed to proceed in the opposite direction – from the Gulf of Maine, around Nova Scotia, and into the southern Gulf of St. Lawrence. Flow fields from a numerical circulation model are used to investigate whether these invasions could be due to drift in ocean currents. Particle tracking experiments are performed and probability density functions (PDFs) derived that describe the probability of drifting a given upstream distance in a given drift time. Analysis of these \\{PDFs\\} revealed that for invasions that took 20–40 y to occur, propagule drift in ocean currents could be responsible for the upstream spread, while this was not the case for short timescale invasions (<10 y). Rafting could be responsible for both short and long timescale invasions.

Ecological evaluation of proposed discharge of dredged material from Oakland Harbor into ocean waters (Phase 3 B of -42-foot project)  

SciTech Connect

The Water Resources Development Act of 1986 (Public Law 99-662) authorized the US Army Corps of Engineers (USACE) San Francisco District, to deepen and widen the navigational channels of the Oakland Inner and Outer Harbors to accomodate deeper-draft vessels. The USACE is considering several disposal options for the dredged material removed during these channel improvements including open-water disposal. Dredged material proposed for open-water disposal must be evaluated to determine the potential impacts of the disposal activity on the water column and disposal site enviromments. The USACE requested that Battelle/Marine Sciences Laboratory (MSL) conduct studies to evaluate open-water disposal options for Oakland Harbor sediments. This request developed into the Oakland Harbor Phase III Program. This is Volume 1 of a two-volume report that presents information gathered to determine the suitability of ocean disposal of sediments dredged from Oakland Harbor. This volume contains project background, materials and methods, results, discussion, and conclusions.

Decadal changes in water mass characteristics at 24{degrees}N in the subtropical North Atlantic Ocean  

SciTech Connect

Three transatlantic hydrographic sections across 24{degrees}N through the center of the subtropical gyre are analyzed for evidence of decadal changes in water mass characteristics. In the main thermocline, there has been a steady increase in salinity from 1957 to 1981 to 1992. The salinity at a given potential temperature between 12{degrees}C and 17{degrees}C has increased at a nearly constant rate of 0.010 per decade; at constant potential density, salinity and temperature both increased at rates of 0.018 per decade and 0.065{degrees}C per decade. In the intermediate waters between 800 and 1500 dbar, salinity has increased as well, on average by as much as 0.025 from 1981 to 1992, either on constant potential temperature or constant density surfaces. These changes cannot be due to vertical having of a constant water mass structure and they cannot be easily explained in terms of horizontal shifts in the subtropical gyre water mass structure. Throughout the water column down to 2000 dbar and across the zonal extent of the 24{degrees}N section, salinity and temperature have broadly increased on density surfaces. Below 2000 dbar, there has been slight cooling and freshening on isopycnal surfaces since 1981. Decadal changes in temperature and salinity from 1981 to 1992 are separated into a component due to vertical motion of the isopycnals and a component due to the changes in temperature and salinity on isopycnals. The remarkable interior warming at constant depth with a maximum increase in temperature at 1100 dbar of nearly VC per century reported from earlier analyses of these sections is due to both processes. The continued warming from 1981 to 1992 has principally been due to changes in water mass characteristics, higher salinities and higher temperatures on isopycnal surfaces. 39 refs., 18 figs., 4 tabs.

Water Power for a Clean Energy Future (Fact Sheet)  

SciTech Connect

This fact sheet provides an overview of the U.S. Department of Energy's Wind and Water Power Program's water power research activities. Water power is the nation's largest source of clean, domestic, renewable energy. Harnessing energy from rivers, manmade waterways, and oceans to generate electricity for the nation's homes and businesses can help secure America's energy future. Water power technologies fall into two broad categories: conventional hydropower and marine and hydrokinetic technologies. Conventional hydropower facilities include run-of-the-river, storage, and pumped storage. Most conventional hydropower plants use a diversion structure, such as a dam, to capture water's potential energy via a turbine for electricity generation. Marine and hydrokinetic technologies obtain energy from waves, tides, ocean currents, free-flowing rivers, streams and ocean thermal gradients to generate electricity. The United States has abundant water power resources, enough to meet a large portion of the nation's electricity demand. Conventional hydropower generated 257 million megawatt-hours (MWh) of electricity in 2010 and provides 6-7% of all electricity in the United States. According to preliminary estimates from the Electric Power Resource Institute (EPRI), the United States has additional water power resource potential of more than 85,000 megawatts (MW). This resource potential includes making efficiency upgrades to existing hydroelectric facilities, developing new low-impact facilities, and using abundant marine and hydrokinetic energy resources. EPRI research suggests that ocean wave and in-stream tidal energy production potential is equal to about 10% of present U.S. electricity consumption (about 400 terrawatt-hours per year). The greatest of these resources is wave energy, with the most potential in Hawaii, Alaska, and the Pacific Northwest. The Department of Energy's (DOE's) Water Power Program works with industry, universities, other federal agencies, and DOE's national laboratories to promote the development and deployment of technologies capable of generating environmentally sustainable and cost-effective electricity from the nation's water resources.
