Description:

Abstract: No formal abstract is given.

Purpose:

This investigation, the first of several planned adjacent to major population centers, was designed to establish a good scientific data base on a segment of continental shelf adjacent to the San Francisco Bay area so as to evaluate and monitor human impact on the marine environment. "

Supplemental_Information:

Data digitized in 2003-2005 for inclusion into usSEABED (<http://walrus.wr.usgs.gov/usseabed>)

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Detailed information is available in the report. For usSEABED, data were digitized, visually compared to the source and corrected. Where appropriate, data were tested for completeness using MS Excel. Locations checked using GIS.

Logical_Consistency_Report: Data fall within normal ranges for the given parameters.

Completeness_Report:

No estimate made for original data. For inclusion into usSEABED, all textural data in the report were included.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Navigation by three systems: GPS, LORAN-C, and a shore-based transponder net. Positional accuracy varied from about 100 m using GPS and LORAN-C to a few meters using the shore-based transponder net.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Water depth determination probably by 3.5 kHz profiling systems. Subsample depths given as nearest centimeter.
