Dataset description: September 2010 bathymetry collected near Dumbarton Bridge in south San Francisco Bay, California

Bathymetric survey data were collected in September 2010 just south of Dumbarton Bridge in south San Francisco Bay, California. Portions of the main channel and western shallows/intertidal mudflats were surveyed using an interferometric sidescan sonar system following procedures detailed in Foxgrover and others, 2011. The bathymetry is provided as a 1-m resolution raster 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).
