Dataset description: April 2013 bathymetry collected near Dumbarton Bridge in south San Francisco Bay, California

Bathymetric survey data were collected in April 2013 just south of Dumbarton Bridge in south San Francisco Bay, California. A portion of the main channel was 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).
