Gravity cores from San Pablo Bay and Carquinez Strait, San Francisco Bay, California
This data release contains information on gravity cores that were collected by the U.S. Geological Survey in the area of San Pablo Bay and Carquinez Strait, California in 1990, 1991, and 2000. Ten (10) pdf files describe gravity cores that were split, photographed, and imaged by X-rays, and another pdf file contains a core-log legend. In addition, a shapefile (sanpablo_spls.shp) provides sample co
San Francisco Bay Delta Bathymetric/Topographic digital elevation model (DEM) - 2016 SF Bay Delta DEM 10-m
A high-resolution (10-meter per pixel) digital elevation model (DEM) was created for the Sacramento-San Joaquin Delta using both bathymetry and topography data. This DEM is the result of collaborative efforts of the U.S. Geological Survey (USGS) and the California Department of Water Resources (DWR). The base of the DEM is from a 10-m DEM released in 2004 and updated in 2005 (Foxgrover and others,

Sediment deposition, erosion, and bathymetric change in central San Francisco Bay: 1855-1979
Central San Francisco Bay is the hub of a dynamic estuarine system connecting the San Joaquin and Sacramento River Deltas, Suisun Bay, and San Pablo Bay to the Pacific Ocean and South San Francisco Bay. To understand the role that Central San Francisco Bay plays in sediment transport throughout the system, it is necessary to first determine historical changes in patterns of sediment deposition and

Mapping South San Francisco Bay's seabed diversity for use in wetland restoration planning
In an effort to understand the role of sediment of South San Francisco Bay (South Bay) salt ponds, an acoustic seabed classification was performed with the condition of over two hundred sediment samples. The success of the large-scale tidal wetland restoration of up to 15,000 acres of South Bay partly depends on the ability of the converted ponds to acquire and retain enough sediment to support
