Afghanistan is endowed with a vast amount of mineral resources, and it is believed that the current economic state of the country could be greatly improved through investment in the extraction and production of these resources. In 2007, the “Preliminary Non-Fuel Resource Assessment of Afghanistan 2007” was completed by members...
Application of the SPARROW model to assess surface-water nutrient conditions and sources in the United States Pacific Northwest
Daniel R. Wise, Henry M. Johnson
2013, Scientific Investigations Report 2013-5103
The watershed model SPARROW (Spatially Referenced Regressions on Watershed attributes) was used to estimate mean annual surface-water nutrient conditions (total nitrogen and total phosphorus) and to identify important nutrient sources in catchments of the Pacific Northwest region of the United States for 2002. Model-estimated nutrient yields were generally higher in...

Fire and vegetation records at the City of Rocks National Reserve (CIRO), south-central Idaho, display the interaction of changing climate, fire and vegetation along the migrating front of single-leaf pinyon (Pinus monophylla) and Utah juniper (Juniperus osteosperma). Radiocarbon dating of alluvial charcoal reconstructed local fire occurrence and geomorphic...
Forest cutting and impacts on carbon in the eastern United States
Decheng Zhou, Shuguang Liu, Jennifer Oeding, Shuqing Zhao
2013, Scientific Reports (3)
Forest cutting is a major anthropogenic disturbance that affects forest carbon (C) storage and fluxes. Yet its characteristics and impacts on C cycling are poorly understood over large areas. Using recent annualized forest inventory data, we estimated cutting-related loss of live biomass in the eastern United States was 168 Tg C...

Revision of Fontes & Garnier's model for the initial 14C content of dissolved inorganic carbon used in groundwater dating
Liang-Feng Han, Niel Plummer
2013, Chemical Geology (351) 105-114
The widely applied model for groundwater dating using 14C proposed by Fontes and Garnier (F&G) (Fontes and Garnier, 1979) estimates the initial 14C content in waters from carbonate-rock aquifers affected by isotopic exchange. Usually, the model of F&G is applied in one of two ways: (1) using a single 13C...

Howard S. Ginsberg, Alan Gettman, Elisabeth Becker, Ananda S. Bandyopadhyay, Roger A. LeBrun
2013, Rhode Island Medical Journal (96) 37-41
West Nile Virus (WNV) and Eastern Equine Encephalitis Virus (EEEV) are both primarily bird viruses, which can be transmitted by several mosquito species. Differences in larval habitats, flight, and biting patterns of the primary vector species result in substantial differences in epidemiology, with WNV more common, primarily occurring in urban...
Simulation of groundwater flow in the "1,500-foot" sand and "2,000-foot" sand and movement of saltwater in the "2,000-foot" sand of the Baton Rouge area, Louisiana
Charles E. Heywood, Jason M. Griffith
2013, Open-File Report 2013-1153
Groundwater withdrawals have caused saltwater to encroach into freshwater-bearing aquifers beneath Baton Rouge, Louisiana. Groundwater investigations in the 1960s identified a freshwater-saltwater interface located at the Baton Rouge Fault, across which abrupt changes in water levels occur. Aquifers south of the fault generally contain saltwater, and aquifers north of the...
