Geologic Mapping Offshore of Rhode Island

Rhode Island Sea Floor Mapping

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is mapping sea-floor geology and sedimentary environments offshore of Rhode Island. This website provides links to bathymetric, sidescan-sonar, sediment, photographic, seismic-reflection, and interpretive datasets, all presented in Geographic Information System (GIS) formats and published as Open-File Reports. Together these datasets show the composition and terrain of the seabed, provide information on sediment transport and benthic habitat, and are part of an expanding series of studies that provide a fundamental framework for research and management activities (for example, wind farms and fisheries) along the Rhode Island inner continental shelf.
