Sediment thickness ranges from 0 to 65 m with a mean of 12 m and a standard deviation of 15 m. Purpose: 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 this data set was derived are available online at https://cmgds.marine.usgs.gov/activity_info.php?fan=z307sc https://cmgds.marine.usgs.gov/activity_info.php?fan=s708sc endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.
