PhD. thesis
No formal abstract is available. "This thesis deals with the geology of the continental terrace off the central coast of Oregon. The study includes the area bounded on the east by the shore line (124 04' W to 124 10' W), on the west by the base of the continental slope, at about 125 20' W, on the south by latitude 43 50' N, and on the north by latitude 44 40' N."
No specific purpose is given in the dissertation.

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.
Location, sample numbers, sampler type, simplistic rock and sediment descriptions, and water depth (Appendix 1), median grainsize, Trask statistics, Inman statistics, and percent sand, silt, clay (Appendix 2), the composition of the sediment sand fractions (Appendix 3), core descriptions (Appendix 4) were all completely digitized. Textural analyses of the rock samples (Appendix 5) and the more extensive rock sample description (Appendix 6) were not digitized and are not included in usSEABED.
Navigation probably by Loran-A and/or radar. Positions given to tenths of minutes.
Depth determination by echosounder. Water depths recorded to nearest fathom; subsample depths given to nearest inch.
The settling tube (Emery 1938) was used for the analysis of most of the sand samples. Samples containing shells and pebbles and some of the samples containing appreciable quantities of glauconite were sieved using a set of standard Tyler screens. Samples containing more than four percent silt and clay were dispersed in 0.2 percent Calgon solution; filtered through a millipore filter to remove seawater, and the sediment residue then covered completely with the Calgon solution to exactly 1000 cc, completely dispersed, and hydrometer readings taking at 1, 2, 15, 30, 60, 120, and 1440 minutes after the dispersion. Following the hydrometer analysis, the sediment was wet sieved through a 0.062 mm screen. The sand fraction was then weighed, and if the sand fraction comprised more than four percent of the sample, it was analyzed using the settling tube. Cumulative curves and particle size statistics were calculated using IBM 1410 and IBM 1620 computers. A split of sand from each sample was spread over the grid on a micropaleontology slide and the composition of 150 to 250 grains were noted with the aid of a binocular microscope.
