Abstract:

"Samples of bottoms sediments were collected for analysis from 121 different positions on the continental shelf and upper continental slope off Oregon between latitudes 44 20'N and 44 48'N. The nature of the sediments suggests that they have been contributed by the geologically varied physiographic provinces of the Pacific Northwest which drain to the Pacific Ocean via the coasts of Oregon and Washington. Well-sorted, fine-grained sub angular sands cover the continental shelf to a depth of 52 fathoms. Below this depth the sediments grade uniformly to clay-silts on the upper continental slope. Rock outcrops, gravel, and coarse sand are present in the vicinity of Stonewall Bank, along the shelf break, and on the shoals rising from the upper part of the continental slope. Mineralogical immaturity characterizes the nearshore sands and the sand fraction of the finer-grained offshore sediment. Glauconite, calcium carbonate, and organic matter are essentially absent from the sands, but may be abundant in the offshore sediment; glauconite up to 91 percent of the sample; calcium carbonate, 14 percent; and organic matter, 6 percent. Small quantities of organic silica, maily sponge spicules and radiolaria, are irregularly distributed in the fine sediments. Textural considerations suggest that the nearshore sands were deposited in a high-energy littoral environment and may be a late Pleistocene transgressive deposit. Although the glauconite-rich sediments on the offshore shoals and at the edge of the continental shelf attest to little or no deposition, shallow depressions and sea valleys of the upper continental slope may be actively receiving sediment."

Purpose:

"The purpose ... is twofold: first, to describe in detail the texture and composition of the sediments found in this area; second, to relate the pattern sedimentation to the physical and chemical forces which formed it."

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:

Digitized data include locations and depths from table 4; textural parameters and statistics from table 5; percent heavy minerals in sand and terrigenous sand fractions from table 6; heavy mineralogy of [selected] samples from table 7. Percents terrigenous sand, organic matter, glauconite, and CaCO3 were read from figures 12, 17, 18, 19 respectively.

Process_Step:

Process_Description:

A settling tube was used for the mechanical size analysis of the sand samples. Those samples contining pebbles or very coarse sand were sieved, using Tyler standard screens. Samples which contained a noticeable amount of material finer than sand were wet-sieved through a 62 micron screen with a 0.2 percent Calgon dispersing solution. Size analyses were then made by the hydrometer method with the pipette method being used to check selected samples. Total carbon content was determined by total combustion in a Leco induction furnace, couple with a Leco gasoline carbon analyzer. Carbonate carbon was also analyzed gasometrically. Heavy minerals were separated from the total samples by the gravity-funnel technique, with bromoform used as the heavy liquid.
