"Measurements of wet density, porosity, grain size distribution, and shear strength were made from cores collected from a variety of environments in the north Pacific. Bearing strength of the sediments was calculated from shear strength measurements and is tabulated with the other properties. Short discussions of shear strength and bearing capacity explain the fundamentals of these parameters."
"The increasing interest in the sea floor as an operational environment has created a demand for data on the capacity of sea-floor sediments to support applied loads. Because very little work has been done on the bearing strength properities of marine sediments, all available data are of interest to those involved in placing equipment on the sea floor."

David G. Moore at the Geological Society of America for the collection and analysis of data. For inclusion into usSEABED: Digitization: Jennifer Mendonca (USGS); Corrections: Jane Reid (USGS) and Chris Jenkins (University of Colorado)
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.
Data fall within normal ranges for the given parameters.
Data not digitized include direct shear strength, vane shear strength, sensitivity, and bearing capacity.
Latitude and longitude are given to the nearest minute-tenth. No navigational information is noted in the paper.
Water depths are given to the nearest meter; downcore information is given to the nearest millimeter.
No information on data techniques or sample protocols is given in the paper.
