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 the given parameters.

Completeness_Report:

For usSEABED all data from Appendices V, VI, and VII were completely digitized.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Navigation techique of Loran A, radar, and bathymetry; some longitudes were corrected due to navigation limitations; these fixes were taken from their relative positions on the seismic record where control is better. Positions given to minute-tenths, and precision given as 2 kilometers.

Vertical_Positional_Accuracy_Report:

Depth determination technique not given in report. Water depths not recorded, but less than 110 meters; subsample depths given to nearest centimeter.

Process_Step:

Process_Description:

The lithified cores were described in detail with the aid of a microscope and color coded using the Geologic Society of America color chart (1963). Since most of the rocks were generally semilithified, they were broken down, disaggregated, and treated as sediment samples. The process consists of repeated cycles of soaking in buffered hydrogen pyroxide and treatment with an ultrasonic probe. The sample was inspected under the microscope at the end of each cycle for the presence of grain aggregates. Distilled water was added to the disaggregated sample and then drawn off through micropore candle filters. A Calgon and water solution was then added to the sample and drawn off by candle filters. The process was repeated three or four times. The sample was wet sieved to remove the sand fraction (>62 microns); it was then dried and weighed. The fine fraction (silt and clay) analysis was done by pipette (Krumbein and Pettijohn, 1938). Percentage of sand, silt, and clay were calculated from these data. A split of at least 300 grains was separated from the sand fraction and counted on a grid. The grains were divided into rock fragments, quartz and feldspars, mafic grains, micas, pyrite, glauconite, biogenous material (forams, sponge spicules, radiolaria, diatoms, etc.). Selected rock samples were thin sectioned and examined with a petrographic microscope. Most samples were too fine grained for petrographic analysis and consequently were not used extensively in the final analysis of this study.
