Biological communities and habitats within sea inlets or the zones where rivers meet the seas which are subject to tidal effects and the mixture of fresh and saltwater.
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.
A white paper describing a plan for USGS research in Gulf of Mexico estuaries, developed in 2001 using Tampa Bay as an example with links to program strategy and design.
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.
Webpage based on USGS Open File Report 98-139 links to information on the San Francisco Bay estuary to study dredge disposal effects, fish habitats, sediment transport, rock pinnacles and navigation, and consequences of a large oil spill.
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.
Sediment from rivers has both beneficial and detrimental effects on ecosystems and human activities around Puget Sound. We explain where the sediment comes from, how it is transported, and the nature of the data that we can use to understand it.
