Marine Geomorphology, Evolution, and Habitats

Oblique map of the seafloor along the San Mateo County coast, color-coded for depth. reds = shallower, towards the right, and blues = deeper, towards the upper left. OVERVIEW

Seafloor resource managers and modelers need seafloor maps that can be combined in GIS, modeling, and statistical analysis environments and related successfully to biologic and oceanographic data. The Marine Geomorphology, Evolution, and Habitats Project encompasses mapping activities and the development of new mapping systems and methodologies. The emphasis is on the role of geologic processes in the evolution of habitats. Interest in USGS habitat maps and habitat change studies remains high.


Develop seafloor habitat map products that directly apply to habitat and offshore energy impact modeling

Improve seafloor maps through combined technologies

Generate USGS map and data publications for California’s State Waters. The California Seafloor Mapping Program (CSMP) is a cooperative program to create a comprehensive coastal/marine geologic and habitat base map series for all of California’s State waters

Determine the geomorphology and seafloor character of the Gulf of Alaska, as a multi-agency cooperative

Generate geo-referenced video mosaics from seafloor video collected by other USGS projects at the Pacific Coastal and Marine Science Center, in cooperation with the University of New Hampshire’s Center for Coastal and Ocean Mapping

Understand the processes that control seafloor stability and the resulting modification of continental shelf geomorphology, sediment distribution, and benthic habitats
