LBA-ECO LC-15 JERS-1 Synthetic Aperture Radar, 1- km Mosaic, Amazon Basin: 1995-1996 . Data set prepared by S.S. Saatchi, B. Nelson, E. Podest, and J. Holt. This data set contains two image mosaics of L-band radar backscatter and two images of derived first order texture. The mosaics were created from 1,500 images collected by the Japanese Earth Resources Satellite-1 (JERS-1) Synthetic Aperture Radar (SAR) over the Amazon River Basin as part of the Global Rainforest Mapping Project (GRMP). Backscatter image mosaics were developed for the dry season of 1995 and the wet season

Nine LBA-ECO Data Sets Released Nine LBA-ECO Data Sets Released The ORNL DAAC announces the release of nine Carbon Dynamics data sets associated with the LBA-ECO component of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA). These Carbon dynamics studies involved the quantification of the carbon pools in vegetation and the rates of carbon exchange among the atmosphere, vegetation, and soils. Ecosystem carbon balance was investigated in a primary tropical forest in central Amazonia using an approach that integrated long-term eddy covariance flux measurements with comprehensive ecological characterization methods. These data are applicable for the investigation of the way in which these rates may be altered by natural and human disturbances. Studies took place in the old-growth upland forest at the Para Western

The LBA Project encompasses several scientific disciplines, or components. The LBA-ECO component focuses on the question: "How do tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in Amazonia?" The Amazon rain forest or Amazonia, is the largest remaining expanse of tropical rain forest on Earth, harboring approximately one-third of all Earth's species. Although the rain forest's area is so large that it

PV-hybrid village power systems in Amazonia  

SciTech Connect (OSTI)

The Brazilian Amazon region is an ideal location for isolated mini-grid systems. Hundreds of diesel systems have been installed to supply electricity to this sparsely populated region. However, the availability of renewable energy resources makes the Amazon well-suited to renewable energy systems. This paper describes the technical aspects of two hybrid systems being installed in this region through the cooperative effort of multiple partners: US Department of Energy, through NREL, and Brazilian CEPEL/Eletrobras and state electric utilities. The first system is a 50-kW photovoltaic-wind-battery hybrid and the second is a 50-kW photovoltaic-diesel-battery hybrid.

A long pollen record from lowland Amazonia: Forest and cooling in glacial times  

SciTech Connect (OSTI)

A continuous pollen history of more than 40,000 years was obtained from a lake in the lowland Amazon rain forest. Pollen spectra demonstrate that tropical rain forest occupied the region continuously and that savannas or grasslands were not present during the last glacial maximum. The data suggest that the western Amazon forest was not fragmented into refugia in glacial times and that the lowlands were not a source of dust. Glacial age forests were comparable to modern forests but also included species now restricted to higher evaluations by temperature, suggesting a cooling of the order of 5{degrees} to 6{degrees}C. 23 refs., 22 tabs.

The consequences of pleistocene climate change on lowland neotropical vegetation  

SciTech Connect (OSTI)

Palynological reconstructions indicate that lowland tropical America was subject to intense cooling during the last ice-age. The descent of presently montane taxa into the lowlands of Amazonia and Minas Gerais indicate temperature depressions ranging from 5[degrees]C to 9[degrees]C cooler-than-present. The strengthened incursion of southerly airmasses caused a reassortment of vegetation throughout Amazonia. Presently allopatric species are found to have been sympatric as novel forest assemblages and formed and dissolved. Modest drying, perhaps a 20% reduction in precipitation, accounts for all the records that show a Pleistocene expansion of savanna. No evidence is found to support the fragmentation of Amazonian forests during glacial times, and the hypothesis of forest refuges as an explanation of tropical speciation is rejected on empirical grounds.

Giant otter population responses to habitat expansion and degradation induced by a mega hydroelectric dam  

Science Journals Connector (OSTI)

Abstract Large hydroelectric dams are major drivers of habitat loss and degradation in lowland Amazonia. Hydroelectric reservoirs reduce the habitat available for terrestrial species, but create new open-water and shoreline lake habitat that can potentially boost populations of aquatic and semi-aquatic species, such as the threatened giant otter (Pteronura brasiliensis). To assess the impacts of mega-dams on this apex-predator, we surveyed the giant otter population across the 443,772-hectare Balbina Hydroelectric Reservoir of central Brazilian Amazonia between 14 and 25years after this reservoir creation. We compared changes in habitat area and estimated giant otter population size between the reservoir pre- and post-filling stages. The Balbina dam created ?3525 islands and increased the open-water surface and total reservoir perimeter available to otters by a factor of 62.7 and 8.9, respectively. Some 25years after damming, however, the estimated post-filling giant otter population size was only twice greater than that estimated before filling and 4.5 times smaller than would be predicted given the total available habitat area and density of dens quantified at a neighbouring undisturbed area used as a surrogate of the pre-filling phase. The observed mismatch between the proportional increase in otter population size and the much greater newly available reservoir habitat area is likely due to low habitat quality in terms of low fish prey productivity and scarcity of suitable sites for denning and territory demarcation. This should be considered in strategic environmental impact assessments of planned hydroelectric dams and in managing existing and future hydropower development in lowland tropical forests.

A 2700calyr BP extreme flood event revealed by sediment accumulation in Amazon floodplains  

Science Journals Connector (OSTI)

Abstract Climatic conditions are one of the most important factors affecting hydrological processes in fluvial systems. Higher discharges are responsible for higher erosion, greater transport, and also higher deposition. Consequently, sediment accumulation in Amazonia floodplain river-connected lakes can be directly related to hydrological patterns of the Amazon River mainstream. In this context, we analyzed five sediment cores taken in two floodplain systems situated in the lower Amazon River, to investigate sediment accumulation patterns during the Holocene. Our records show abrupt fluctuations in sedimentation rates in lakes that can reach more than 2cm/yr during some periods. We find that in all cores, sediment stratigraphy is characterized by packages of sediments of uniform age, which are typically 1080cm thick and present a variegated color. The 14C age of the upper package is about 2700calyr BP. During this abrupt event, sediment accumulation rates in floodplain lakes can be at least 200 times higher than those of normal periods. This sedimentation event is interpreted as being the consequence of one or several successive extreme floods. The 2700calyr BP event has been also observed in other sites in South America and other regions in the world, although different impacts can be observed in each system. This event probably corresponds to a conjunction of favorable conditions for extreme Amazon discharge associated with the Middle to Late Holocene increase of austral summer insolation and shifts of the Intertropical Convergence Zone (ITCZ) from northern to southern positions. In this context, a marked negative peak in solar irradiance at 2700calyrs BP seems to have provoked cooling on the continents and a southward shift of the ITCZ associated with a probable reduction in the Atlantic Meridian Overturning Circulation.
