Abstract:

"The following work is part of a continuing study of the sediments and sedimentary processes of the continental shelf of central California done in cooperation between the University of California, Berkeley, and the Coastal Engineering Research Center, U.S. Army Corps of Engineers. Sediment analyses of the samples were done at the University of California, Berkeley, utilizing the facilities of the Department of Civil Engineering, and Geology, and the Institude of Marine Resources."

Purpose: No specific purpose was cited in the report.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

No estimate made for the accuracy of the data in the original report. 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:

Data fall within normal ranges for phi-size classes and statistical values.

Completeness_Report:

All data were digitized, except graphical cumulative and class grainsize values.

Lineage:

Process_Step:

Process_Description:

Marine bottom samples were obtained with an orange peel grab sampler from the converted fishing boat San Michele; marine samples were obtained from the shoreline to 300 feet below sea level. Intertidal beach samples were obtained using a pipe coring device, inserted into the beach at approximately mid to low tide level, obtaining upper six to ten inches of sediment. In the laboratory, the samples were analyzed at half phi intervals through the entire range of sediment size spread. The finer grained samples were supplemented by pipette analysis. ... was made at half phi intervals and carried to a lower limit of 7 phi.
