Description:

Abstract: No formal abstract is given.

Purpose:

In response to the 1992 creation of the Monterey Bay National Marine Sanctuary (MBNMS), the United States Geological Survey (USGS) initiated a multiyear investigation of the Sanctuary continental margin. As part of the investigative effort, this report summarizes the shipboard procedures, subsequent laboratory analyses, and data results from three seafloor sampling cruises conducted on the continental shelf between the Monterey peninsula, CA, and San Francisco, CA (fig. 1). The cruises were conducted in 1995 aboard the NOAA Ship McArthur (M-1-95-MB) and in 1995 and 1997 aboard the R/V Point Sur (P-2-95-MB and P-1-97-MB). Scientists and representatives from the Environmental Protection Agency (EPA), the National Oceanic and Atmospheric Administration (NOAA), the California Department of Fish and Game (CDFG), the University of California Santa Cruz (UCSC), and the San Jose State University Moss Landing Marine Laboratory (SJSU-MLML) supported the research effort.

Supplemental_Information:

Some data are duplicated in USGS OFR 97-450. Carbonate and organic carbon data from that report are included in this dataset. Data included in usSEABED (<http://walrus.wr.usgs.gov/usseabed>)

Attribute_Accuracy:

Attribute_Accuracy_Report:

See report <http://pubs.er.usgs.gov/pubs/ofr/ofr01107>. Data digitized by the USGS and partners were visually compared to the source data, and corrected. Where appropriate, data were tested for completeness using MS Excel. Locations checked using GIS.

Logical_Consistency_Report: See report <http://pubs.er.usgs.gov/pubs/ofr/ofr01107>

Completeness_Report:

See report <http://pubs.er.usgs.gov/pubs/ofr/ofr01107>. For inclusion into usSEABED, all data in the report were included.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

"Ship positioning was determined by differential GPS (accuracy 10 m);cores typically are obtained within 50 m of the predetermined sampling location."

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

"Water depth at the time of sampling was determined by use of a 12-kHz acoustic profiler."
