Physical Habitat

Benthic substrate for west coast continental margin  (176MB). 
Geological seafloor characteristics of the continental margin of the United States West Coast.  Seafloor types are classified according to Greene et. al. (1999) deep-water marine benthic habitat scheme. Seafloor feature interpretation was performed by West Coast geologic mapping experts as a synthesis of various source data sets, including side-scan sonar, bottom samples, seismic data, and multibeam bathymetry.  The Active Tectonics and Seafloor Mapping Lab, College of Oceanic and Atmospheric Sciences, Oregon State University developed the data for Oregon and Washington.  The Center for Habitat Studies, Moss Landing Marine Laboratories  developed the data for California.  Users are strongly encouraged to review the original source documents for portions of the data off the Oregon and Washington coast and data off the California coast.
