In 2008, the U.S. Geological Survey began mapping the main channel and shallow intertidal mudflats between the Dumbarton Bridge and a railroad bridge located 1 km to the south in south San Francisco Bay. This information was collected to document bathymetric change before and after restoration to inform the South Bay Salt Pond Restoration Project (https://www.southbayrestoration.org), which initiated the restoration of a former salt pond (SF2) on the western shore in 2010. In 2011, following the collection of eight bathymetric surveys, funding for this site-specific project came to an end, yet the location remained an instrumentation calibration site for ongoing research in Alviso Slough (Foxgrover and others, 2011). The calibration surveys collected near the Dumbarton Bridge resulted in an additional eight surveys, collected primarily in the main channel, from 2013 to 2019.
All 16 surveys were collected using U.S. Geological Survey's research vessel R/V Parke Snavely equipped with an interferometric sidescan sonar system, following the procedures detailed in Foxgrover and others, 2011. The bathymetry is provided here as 1-m resolution rasters in geoTIFF format, referenced to the vertical datum of mean lower low water (MLLW). To convert to the North American Vertical Datum of 1988 (NAVD88), subtract a static offset of 0.37 m (datum conversions provided in Foxgrover and others, 2007).

San Francisco Bay geomorphology
Bathymetry and digital elevation models of Coyote Creek and Alviso Slough, South San Francisco Bay, California
2005 hydrographic survey of south San Francisco Bay, California
San Francisco Bay geomorphologyThe primary objective of this task is to develop tools for predicting the long-term geomorphic evolution of estuaries. Sediment core and historical change analysis will be used in combination with interpretation of high-resolution seismic profiles to develop tools for predicting geomorphic evolution of estuaries. Historical change analysis will use hydrographic and lidar data. Longer-term data...
Bathymetry and digital elevation models of Coyote Creek and Alviso Slough, South San Francisco Bay, CaliforniaIn 2010, the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center completed three cruises to map the bathymetry of the main channel and shallow intertidal mudflats in the southernmost part of south San Francisco Bay. The three surveys were merged to generate comprehensive maps of Coyote Creek (from Calaveras Point east to the railroad bridge) and Alviso Slough (from the bay to
2005 hydrographic survey of south San Francisco Bay, CaliforniaAn acoustic hydrographic survey of South San Francisco Bay (South Bay) was conducted in 2005. Over 20 million soundings were collected within an area of approximately 250 sq km (97 sq mi) of the bay extending south of Coyote Point on the west shore, to the San Leandro marina on the east, including Coyote Creek and Ravenswood, Alviso, Artesian, and Mud Sloughs. This is the first survey of this scal
