USFWS selected geographic analyses
The geographic information system (GIS) used by the National Wetlands Research Center (NWRC) of the U.S. Fish and Wildlife Service has been valuable in assisting natural resource managers in planning and managing coastal fish and wildlife resources. In the past 5 years, NWRC has conducted about 60 studies employing this technology. Applications have ranged from simple natural resource inventories

Global climate change: USFWS coastal research
Scenarios of global climate change are still ambiguous; however, increasing sea level and atmospheric carbon dioxide (CO2) concentrations seem certain, although rates of change are still being debated. Predictions for other aspects of climate change, such as temperature, tropical storm frequency and intensity, and precipitation, are still in debate, and all predictions for local (e.g., watershed)

Remote sensing of water quality
Water property data were collected within 3 cooling water reservoirs (active to inactive, large [1,068 ha] to small [68.6 ha]. oligotrophic to eutrophic) at 31 locations. A description of the water characteristics was obtained including algal pigments, total suspended particles, dissolved and particulate organic matter, and total particle absorption spectra. Field data included generated water vol

Geochemical evolution of acidic ground water at a reclaimed surface coal mine in western Pennsylvania
Concentrations of dissolved sulfate and acidity in ground water increase downflow in mine spoil and underlying bedrock at a reclaimed surface coal mine in the bituminous field of western Pennsylvania. Elevated dissolved sulfate and negligible oxygen in ground water from bedrock about 100 feet below the water table suggest that pyritic sulfur is oxidized below the water table, in a system closed to

The distribution of seabirds and fish in relation to ocean currents in the southeastern Chukchi Sea
In late August 1988, we studied the distribution of seabirds in the southeastern Chukchi Sea, particularly in waters near a major seabird colony at Cape Thompson. Foraging areas were characterized using hydrographic data obtained from hydroacoustic surveys for fish. Murres (Uria spp.) and Black-legged Kitttiwakes Rissa tridactyla breeding at Cape Thompson fed mostly on Arctic cod, which are known

The West Antarctic rift system, a propagating rift "captured" by a mantle plume
The West Antarctic rift system, marked by a 3-5-kilometer high shoulder from northern Victoria Land to the Ellsworth Mountains, extends through the Ross Embayment and the Byrd Subglacial Basin. Geophysical data suggest that the ice covered area beneath the rift zone is underlain by Cenozoic volcanic rocks (flood basalts?), and extended crust about 20 km thick. Exposed bimodal alkaline volcanic roc
