Habitat--Offshore of Refugio Beach, California

This part of SIM 3319 presents the habitat map of the seafloor (see sheet 7) offshore of Refugio Beach, California (vector data file is included in "Habitat_RefugioBeach.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreRefugioBeach/data_catalog_OffshoreRefugioBeach.html). Using multibeam echosounder (MBES) bathymetry and backscatter data, potential marine benthic habitat maps were constructed. The habitats were based on substrate types and documented or "ground truthed" using underwater video images and seafloor samples obtained by the USGS. These maps display various habitat types ranging from flat, soft consolidated sediment-covered seafloor to hard, deformed (folded) or highly rugose and differentially eroded bedrock exposures. Rugged, high relief rocky outcrops that have been eroded to form ledges and small caves are ideal habitat for rockfish (Sebastes spp.) and other bottom fish such as lingcod (Ophiodon elongatus). Habitat maps will be presented in a map format generated in a GIS (ArcMap) and both digital and hard copy versions will be produced.
