Short Description

Coverage of the U.S. CRM

Statement: Integrated bathymetric-topographic relief models of U.S. coasts; 3 arc-second (~90 m) cell size

Abstract: The 3 arc-second U.S. Coastal Relief Model (CRM) provides the first comprehensive view of the U.S. coastal zone, integrating offshore bathymetry with land topography into a seamless representation of the coast. The CRM spans the U.S. East and West Coasts, the northern coast of the Gulf of Mexico, Puerto Rico, and Hawaii, reaching out to, and in places even beyond, the continental slope.

Bathymetric data sources include the U.S. National Ocean Service Hydrographic Database, the U.S. Geological Survey (USGS), the Monterey Bay Aquarium Research Institute, the U.S. Army Corps of Engineers, and various other academic institutions. Topographic data are from the USGS and the Shuttle Radar Topography Mission (SRTM). Volumes 3 through 5 also use bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of Mexico project.

-|Extended data description=This Coastal Relief Gridded database (3 Arc Second) that is modeled, provides the first comprehensive view of the US Coastal Zone; one that extends from the coastal state boundaries to as far offshore as the NOS hydrographic data will support a continuous view of the seafloor. In many cases, this seaward limit reaches out to, and in places even beyond the continental slope.

-Bathymetric data sources include the US National Ocean Service Hydrographic Database, the US Geological Survey (USGS), Monterey Bay Aquarium Research Institute (MBARI), US Army Corps of Engineers LIDAR (SHOALS), and various other academic institutions. Topographic data are from the USGS 3-arc-second DEMs and Shuttle Radar Topography data (SRTM). Volumes 3 through 5 also use bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of Mexico project as input to the gridding process.
