Endangered fish threatened by Asian fish tapeworm
Rebecca A. Cole
2004, Fact Sheet 2005-3057
The Asian fish tapeworm, an exotic parasite, has invaded the endangered humpback chub (Gila cypha) population from the Colorado and Little Colorado Rivers in Grand Canyon, Arizona.

A decision support system for map projections of small scale data
Michael P. Finn, E. Lynn Usery, Stephan T. Posch, Jeong Chang Seong
2004, Scientific Investigations Report 2004-5297
The use of commercial geographic information system software to process large raster datasets of terrain elevation, population, land cover, vegetation, soils, temperature, and rainfall requires both projection from spherical coordinates to plane coordinate systems and transformation from one plane system to another. Decision support systems deliver information resulting in knowledge...

The Chicot aquifer system is the principal source of fresh ground-water supplies in southwestern Louisiana. Much of the area is rural and rice cultivation is the primary agricultural activity. About 540 million gallons per day were withdrawn from the aquifer system in southwestern Louisiana in 2000. Potentiometric-surface maps of the...
Simulated effects of pumping and drought on ground-water levels and the freshwater-saltwater interface on the north fork of Long Island, New York

An autonomous, electromagnetic seepage meter to study coastal groundwater/surface-water exchange
Peter W. Swarzenski, Matt Charette, Christian D. Langevin
2004, Open-File Report 2004-1369
The bi-directional exchange of groundwater with coastal surface waters may influence not only coastal-water and geochemical budgets, but may also impact and direct coastal ecosystem change. For example, the widespread discharge of nutrient-enriched submarine groundwater into an estuary or lagoon may contribute directly to the onset and duration of eutrophication,...
