Description:

Abstract:

This data release contains information on 94 gravity cores and 3 box cores that were collected by the U.S. Geological Survey in the areas of Suisun, San Pablo, and San Francisco Bay, California in 1990 and 2000. PDF files describe the cores that were split for analysis, and another pdf file contains a core-log legend. In addition, a shapefile provides sample collection data.

Purpose:

The examination of these cores was a continuation of analysis of 72 gravity cores from the same field surveys published in Woodrow and others in 2017 and adds to the analysis of cores collected in San Francisco Bay by Anima and others 2005. These data are intended for science researchers, students, policy-makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information.

Supplemental_Information:

Additional information about the field activities from which these data were derived are available online at:

Although this Federal Geographic Data Committee-compliant metadata file is intended to document the dataset in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.
