The flow of water in a body of water due to wind or other forces or variations in density or temperature. Use 'water circulation' for situations that are not specifically covered by narrower terms. Use 'ocean circulation' for water circulation in the oceans.
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.
Suspended-sediment concentration data were collected in San Francisco Bay during water year 2000 using optical backscatterance sensors and water samples. This report presents the data-collection methods, data, and calibration plots.
Tide stage, specific conductance, water temperature, and freshwater inflow at selected Hudson River (New York) gages updated every 4-hours to measure the effects of freshwater withdrawals and upstream movement of the salt front.
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.
Describes and provides links to USGS research in the location of the estuary and coast of Long Island, New York, to map the sea floor and to study sediment transport, contaminants, and sand resources and coastal vulnerability.
