Publication_Place: San Jose

Publisher: San Jose State College (University)

Description:

Abstract: No formal abstract is given in the report.

Purpose:

" The objectives of this study include 1) determination of the textural and depositional characteristics of the recent marine sediments, 2) establishment of the distribution of the foraminifera, and 3) relating the distribution of the foraminifera to environmental factors."

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

No estimate made for the original data. For inclusion into usSEABED, locations and statistical data were digitized by hand (typed in), visually compared to source and corrected as needed. Where appropriate, data were tested for completeness using MS Excel.

Logical_Consistency_Report: Data fall within normal ranges for given parameters.

Completeness_Report:

No estimate made for the original data. For inclusion into usSEABED, collecting date and depth at MLLW were digitized from Appendix A. Appendix B (Physical data of the sediments) was completely digitized. Appendices C (Percent of living population and live diversity data) D (Percent of total population and totoal species diversity data), and E (Foraminiferal population data) were not digitized.

Process_Step:

Process_Description:

Particle size analyses by Emery settling tube (Emery, 1938) for the coarser than 62 micron fractions (i.e., sand), and standard pipette methods (Krumbein and Pettijohn, 1938) for the finer than 62 micron fractions (i.e., silt and clay). Pipette analyses included pretreatment of samples with hydrogen peroxide to remove organic matter and filtering with porcelain filters to remove soluble salts. Sodium hexametaphosphate was added in known concentrations to further prevent flocculation of the samples.
