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.
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.
Research projects intended to create regional and national data that conform to conditions predicted by general circulation models, so that land and wildlife managers can understand the likely consequences of climatic changes in their areas of study.
USGS project to understand coastal evolution and modern beach behavior; to identify and model the physical processes affecting coastal ocean circulation and sediment transport; and to identify sediment sources and construct a regional sediment budget.
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.
A broad survey of regional patterns in stream flow nationwide. Maps and graphs summarizing streamflow conditions for water-year 2007 (October 1, 2006 to September 30, 2007) in the context of the 78-year period 1930-2007.
