Nearshore Benthic Habitat GIS for the Channel Islands National Marine Sanctuary and Southern California State Fisheries Reserves Volume 1


Habitat in the South San Miguel study area is rocky. Sidescan imaging was impeded in water depths less than 20 m by extensive kelp, which infers large areas of rock in those water depths. Rocky area persists out to the shelf break south of San Miguel Island. Extensive areas of sand waves suggest strong bottom currents are common in this area.
Screen capture from ArcView window showing the color-coded habitats derived from sidescan sonar including reserve boundaries and coastline.
