San Francisco Bay Interferometric Bathymetry: Area B

Published by Office for Coastal Management | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: December 19, 2025 | Last Modified: 2016-01-01T00:00:00.000+00:00
High resolution sonar data were collected over ultra-shallow areas of the San Francisco Bay estuary system. Bathymetric and acoustic backscatter data were collected simultaneously in 10 survey blocks. All of these blocks were surveyed with 100% cover of backscatter imagery. 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. Interferometric sidescan bathymetry data were acquired using a 468 kHz Bathyswath sonar system aboard the RV MacGinitie and RV Kelpfly. Both of these platforms were well suited to acquire data in the very shallow subtidal areas of the bay.
