    • San Francisco Bay Interferometric Side Scan Imagery: Area A

    Metadata Updated: April 15, 2024

    Backscatter imagery data were collected over shallow subtidal areas in the San Francisco Bay estuary system. Bathymetric and acoustic backscatter data were collected simultaneously in 84 survey blocks. Seventy five of these blocks were surveyed with 100% cover of backscatter imagery and nine blocks were surveyed with 50% backscatter coverage. These data were collected as source material for planned benthic habitat mapping. An earlier project had been completed to map the very-shallow subtidal and intertidal areas using optical methods. These mosaics were collected with the Edgetech 6205 sonar system in the San Francisco Bay. For this San Francisco Bay habitat mapping project, seventy-five survey blocks were acquired with the Edgetech 6205 sonar, as these seventy-five areas contained water depths that were predominantly shallower than 20 meters and thus more efficiently mapped using side-scan sonar methods.
