Comments
South Bay Salt Ponds. This effort is part of a multi-disciplinary GD/BRD/WRD study entitled Effects of regional wetland restoration on mud flats of the South San Francisco Bay: avian ecology, food webs, and sediment supply . Other surveys included in this effort: S-16-08-SF, S-1-09-SF, S-3-09-SF, S-9-09-SF, S-1-10-SF, S-10-10-SF.
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).
