Contains data from two USGS national stream water-quality networks, the Hydrologic Benchmark Network (HBN) and the National Stream Quality Accounting Network (NASQAN). Data includes sampling, streamflow measurements, station attributes, and quality control data, as well as documentation of important changes in field and laboratory methods, etc. Also contains USGS open-file report 96-337, Data from selected U.S. Geological Survey national stream water-quality...

Interactive CD-ROM that contains images, maps, movies, and data from all surveys the Pacific Seafloor Mapping Project has completed up to January 1999. Contains shaded relief of bathymetry, backscatter, oblique and 3-D views, and QuickTime movies. Also contains ARC/INFO export (.e00) files and full-resolution TIFF images of all sites that can be downloaded and used in many GIS packages.

The degradation in performance for eight photovoltaic (PV) modules stressed at high voltage (HV) is presented. Four types of modules -- tandem-junction and triple-junction amorphous thin-film silicon, plus crystalline and polycrystalline silicon modules -- were tested, with a pair of each biased at opposite polarities. They were deployed outdoors between 2001 and 2009 with their respective HV leakage currents through the module encapsulation continuously...

The Metals and Ceramics Research Branch (MCRB) of the Weapons and Materials Research Directorate is providing ceramic material characterization and evaluation to the Tank Automotive Research, Development, and Engineering Center (TARDEC) as a part of a project entitled "Fighting Vehicle Propulsion Technology Using Ceramic Materials." Through research and exploratory development of advanced ceramics and other technologies, the objective of this project...

Presents an updated model of Juan de Fuca slab beneath southern British Columbia, Washington, Oregon, and northern California. Most significant improvements include a gridded slab surface in geo-referenced ArcGIS format; continuation of slab surface to its full northern and southern edges; extension of slab surface from 50-km depth down to 110-km beneath Cascade arc volcanoes; and revision of slab shape based on new seismic-reflection and seismic-refraction...

The Department of Defense (DOD) plans to increase its military presence on Guam from about 15,000 in 2009 to more than 39,000 by 2020 at a cost of more than $13 billion. The growth will create temporary construction jobs and permanent civilian jobs with the military, with contractors, and in the Guam community. GAO was asked to examine the extent to which DOD and the government of Guam have (1) planned for temporary construction labor requirements...

In 2010, NATO decided to expand its ballistic missile defense program, in part because of the American offer to include its European Phased Adaptive Approach (EPAA) as the centerpiece of an expanded effort. For the Allies' part, few have actually contributed tangible ballistic missile defense assets, in terms of missile interceptors, radars or other sensors, or ballistic missile defense-related platforms. This is likely to have significant implications...

Winchester/Camberley Homes with the Building America program and its NAHB Research Center Industry Partnership collaborated to develop a new set of high performance home designs that could be applicable on a production scale. The new home designs are to be constructed in the mixed humid climate zone four and could eventually apply to all of the builder's home designs to meet or exceed future energy codes or performance-based programs. However, the...
