  • Gas fired absorption heat pumps for space conditioning (heating and air conditioning) are being developed by several US organizations. Single-effect cycle absorption heat pumps for residential applications were developed in the 1970's, but proved to be uneconomic and were not manufactured. Advanced cycle absorption heat pumps with substantially higher efficiencies are now being developed, and have the potential to be economically attractive to consumers.
  • Cretaceous rocks are widespread along the Pacific margin of North America and record the presence of various plutonic, metamorphic, and volcanic events, basin types, depositional systems, and tectonic regimes. More accurate time-stratigraphic divisions of Cretaceous rocks, based on improved biostratigraphic zonations and new radiometric dating, permit both improved paleogeographic and reconstructions and correlations with changes in global sea level, climate, and oceanic paleocirculation patterns. Better understanding of the mobility and interaction of tectono-stratigraphic terranes along the Pacific margin, supported by paleomagnetic studies of increased accuracy, have forced us to reevaluate all previous paleotectonic and paleogeographic reconstructions. Major accretionary events, markedmore » by regional structural deformation, metamorphism, and plutonism, characterized the Pacific margin in the Jurassic. The Cretaceous paleogeographic framework, in general, reflects the reconstruction of the margin into a more continuous and less complex magmatic arc, forearc basin, and subduction complex. The Paleogene was marked by renewed disruption, translation, dispersion, and accretion in most areas. Active Cretaceous magmatic belts were present, from south to north, in the Mojave Desert, Sierra Nevada, Idaho batholith, North Cascades, Coast plutonic complex, and Alaska Range. Cretaceous plutonic belts in the Salinian block, Transverse Ranges, and Peninsular Ranges of Alta and Baja California formed far south of their present locations and did not accrete until the Paleogene. Forearc basins west and south of the magmatic arcs were widespread and generally characterized by thick sequences of turbidites.« less
  • High levels of mercury have been found in fish from lakes throughout the northeastern US and eastern Canada, in waters with no known local mercury source. If this mercury originates from anthropogenic emissions to the atmosphere, deposition should be higher near population centers or other point sources. The authors surveyed the mercury content of late-season snowpack, sphagnum moss, and fish at locations from southwestern Connecticut to northern Newfoundland to determine if such a pattern existed. Mercury in snow ranged 1.5 to 20 ng/L, and in sphagnum < 24 to 289 ng/g dry wt. Concentrations were generally highest at southwestern sitesmore » and lowest at northeastern sites with some exceptions. The highest concentrations in both media were at locations in Rhode Island and New Hampshire, and may reflect local source emissions. Excluding these sites, the range in concentration from south to north is only a factor of two or three. These values are similar to those reported in other areas and reflect the long atmospheric residence time of gaseous elemental mercury. Mercury concentration in fish ranged 0.1 to 1.0 ug/g wet wt. and showed no regional pattern. Rather, fish mercury concentration was affected by fish species and size, being highest in large predatory species such as smallmouth bass (Micropterus dolomieu), and lowest in small nonpredatory species such as yellow perch (Perca flavescens) and brook trout (Salvelinus fontinalis).« less
  • The North American Energy Working Group (NAEWG) was established in 2001 by the governments of Canada, Mexico, and the United States. The goals of NAEWG are to foster communication and cooperation on energy-related matters of common interest, and to enhance North American energy trade and interconnections consistent with the goal of sustainable development, for the benefit of all three countries. At its outset, NAEWG established teams to address different aspects of the energy sector. One, the Energy Efficiency Expert Group, undertook activity in three areas: (1) analyzing commonalities and differences in the test procedures of Canada, Mexico, and the Unitedmore » States, and identifying specific products for which the three countries might consider harmonization; (2) exploring possibilities for increased mutual recognition of laboratory test results; and (3) looking at possibilities for enhanced cooperation in the Energy Star voluntary endorsement labeling program. To support NAEWG's Expert Group on Energy Efficiency (NAEWG-EE), USDOE commissioned Lawrence Berkeley National Laboratory, representing the Collaborative Labeling and Appliance Standards Program (CLASP), to prepare a resource document comparing current standards, labels, and test procedure regulations in Canada, Mexico, and the United States. The resulting document identified 46 energy-using products for which at least one of the three countries has energy efficiency regulations. Three products--refrigerators/freezers, room air conditioners, and integral horsepower three-phase electric motors--have identical minimum energy performance standards (MEPS) and test procedures in the three countries. Ten other products have different MEPS and test procedures, but have the near-term potential for harmonization. NAEWG-EE is currently working to identify mechanisms for mutual recognition of test results. With consultative support from the United States and Canada through NAEWG-EE, Mexico is exploring possibilities for extending the Energy Star endorsement label to Mexico.« less
  • Fluids from the western margin of the Basin and Range have helium isotope ratios as high as {approx}6-7 Ra, indicating a strong mantle melt influence and consistent with recent and current volcanic activity. Moving away from these areas, helium isotope ratios decrease rapidly to ''background'' values of around 0.6 Ra, and then gradually decrease toward the east to low values of {approx}0.1 Ra at the eastern margin of the Basin and Range. Superimposed on this general regional trend are isolated features with elevated helium isotope ratios (0.8-2.1 Ra) compared to the local background. Spring geochemistry and local geology indicate thatmore » these ''He-spikes'' are not related to current or recent magmatic activity, suggesting that the spikes may reflect either localized zones deep mantle melting or deep permeable pathways (faults) with high vertical fluid flowrates. A detailed study of one of the He-spikes (Dixie Valley and the Stillwater Range Front Fault system), indicates that features with high 3He/4He ratios are confined to the range front normal faults characteristic of the extensional regime in the Basin and Range, suggesting that these faults are deep permeable pathways. However, not all range front fault systems transmit fluids with a mantle signature, implying that not all have deep permeable pathways.« less
