Abstract:

"A German coring device (Reineck, 1958) has been improved to obtain oriented undisturbed cores at any depth of water. The samples are rectangular in shape, 8x12 inches in plan and a maximum of 18 inches high. Good cores have been obtained from clayey material as well as from gravelly sand. No disturbances due to coring were observed on the collected samples. These large samples make it possible to conduct many varieties of investigations, such as study of living organisms and shear strength measurements, as soon as the sample is on deck of a ship; radiography of slices, peeling and impregnation techniques, granulometry, mineralogy, porosity, fossil contents, etc. Construction and use of the box core and applications of some of these analytical techniques are described."

Purpose: Samples were collected as trials for the sampler.

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: None available

Completeness_Report:

Only those samples within the U.S. EEZ were digitized. Eighteen samples in the Gulf of California are not included. Orientation was not digitized.
