Woodrow Originator: Kevin Orzech Publication_Date: 20240322 Title: Gravity Cores and Box Cores from Suisun Bay, San Pablo Bay, and San Francisco Bay, California Geospatial_Data_Presentation_Form: Portable Document Format (PDF), shapefile Publication_Information: Publication_Place: Pacific Coastal and Marine Science Center, Santa Cruz and Menlo Park, CA Publisher: U.S. Geological Survey, Coastal and Marine Geology Program Online_Linkage: https://doi.org/10.5066/P9G7VZZQ 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: http://cmgds.marine.usgs.gov/fan_info.php?fan=J200SF http://cmgds.marine.usgs.gov/fan_info.php?fan=J290SF Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. 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.
