Overview of the Southeastern Amphibian Research and Monitoring Initiative, annual report, field methods and protocols, statistical design and analysis, glossary, projects, and lists of frogs, toads and salamanders.
Links to information on species of frogs, toads, and salamanders located in the southeastern United States and the U.S. Virgin Islands, with information on appearance, habitats, calls, and status, plus photos, glossary, and provisional data.
Provides geologic, geophysical, and geochemical framework studies that will aid in a reassessment of energy commodities (coal, gas, and oil) in the Gulf Coast Region.
We estimated the volume of oil, natural gas, and natural gas liquids in three closely related geologic units in this area using a geology based assessment methodology.

Consistent, historic, and up-to-date surface-water data, such as gage height (stage) and streamflow (discharge), collected at major rivers, lakes, and reservoirs, downloadable from the USGS National Water Information System as graphs, tables, or files.
Consistent, historic, and up-to-date ground-water data, such as water levels collected at wells and springs, are available from the USGS National Water Information System as graphs, tables, or files to download.
Consistent, real-time water data from streams, lakes, reservoirs, ground-water, and meteorological sites, are available from the USGS National Water Information System as graphs, tables, or files to download.
Report prepared for the U.S. Fish and Wildlife Service with descriptions of exotic aquatic species introduced in the southeast United States with information on populations, geographic distribution, and origins.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is conducting an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii.
