Article from American Scientist on study of the San Francisco Bay estuary as a component of the global climate system showing that natural fluctuations might be mistaken for anthropogenic trends affecting waterflow and salinity.
Main page for accessing links for information and data on the San Francisco Bay estuary and its watershed with links to highlights, water, biology, wetlands, hazards, digital maps, geologic mapping, winds, bathymetry and overview of the Bay.
Project of the Gulf of Mexico Integrated Science program that evaluates the transport and sedimentation of contaminates through the Mississippi River and Atchafalaya River delta to the near-shore Gulf of Mexico. Includes aerial photographs.
Biomonitoring of Environmental Status and Trends (BEST) program is designed to assess and monitor the effects of environmental contaminants on biological resources with links to detailed information on specific species.
Identification of epiphytes (plants obtaining moisture and nutrients from the air and rain and usually living on another plant) on seaweed in Tampa Bay, Florida. Abstract of symposium presentation with photos.
Information on USGS studies of Chesapeake Bay, the nation's largest estuary, concerned with water quality, ecosystem history and change, vital habitat and biological resources, and land use studies.
Declines in fish and wildlife populations, water-quality issues, and changes in coastal habitats have prompted this USGS study of the region's nearshore life and environment.
Includes links to data from published reports.
Field methods, topics of investigation, shoreline changes, publications, and satellite imagery related to geologic and hydrologic processes affecting Lake Pontchartrain and adjacent lakes which form a large estuary in the Gulf Coast region.

Website of the Gulf of Mexico Integrated Science program to understand the framework and processes of the Gulf of Mexico using Tampa Bay as a pilot study. Links to publications, digital library, water chemistry maps, epiphytes, and field trips.
Review of a study monitoring changes in salinity in Alligator Bay, NC during a 1996 hurricane due to the influx of fresh and saltwater and the effect it would have on oyster aquaculture.
Provides location-depth grids of bathymetry available for San Francisco Bay and tools for examining those grids. Data provided as GIS grids and animations.
Report on satellite imagery collected by the NOAA Advanced Very High Resolution Radiometer (AVHRR) on NOAA polar-orbiting weather satellites. Links are provided to imagery of north-central Gulf of Mexico and of the Lake Pontchartrain.
