Airborne scanning laser surveys (LIDAR) are used to obtaining data to investigate the magnitude and causes of coastal changes that occur during severe storms. Links to examples of coastal mapping during specific hurricanes.
Investigation of the upper- and middle continental slope of the Mississippi Canyon, including the Gulf of Mexico, for the distribution of gas-hydrate deposits with links to a DEM image map, bathymetry data, and research technology.
Results of ground-surface monitoring and borehole water table measurements document subsidence of the land surface correlative with changes in the ground water.
Online report for an interactive workshop Impact of Climate Change and Land Use in the Southwestern United States. Discusses land subsidence due to increased ground water pumping in the Southwest and the damage caused by subsidence.
Homepage linking the historic journey of Lewis and Clark and the research of the USGS in the same region with links to mapping history, remarkable points on the Missouri River, educational activities, photo gallery, and publications.
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.
Report provides the multibeam bathymetry and acoustic backscatter data, images, FGDC-compliant metadata, and GIS data from the 2002 surveys and 1997 USGS surveys of the Gulf.
Report on multibeam sonar imaging to produce bathymetric mapping of the reef tract known as The Pinnacles, northern Gulf of Mexico with links to images (ASCII or ArcInfo formats), data, metadata, ArcExplorer 2.0 project, and cruise report.
Georeferenced high-resolution mapping of bathymetry of the West Florida Shelf, Gulf of Mexico of areas suspected to be critical benthic habitats for fisheries. Includes links to images, data, metadata, and TIFF image files.
