Supplemental_Information: " This report documents textural and mineralogical analyses of surface sediment from the shelf and upper slope of the continental margin west of the Russian River, Northern California (Fig. 1). The samples were collected on cruises V180NC, L180NC,and L1381NC. Fifty-six sampling stations were occupied (Fig. 2 and Table 1) and sediment samples were collected using gravity, piston trigger-weight, van Veen and box corers."

Discussion of data in the setting and conclusions are provided. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: For the original data, replicate analyses and calibration tests show that the RSA has a precision of +/- 5% and an accuracy of +/- 5%, and that the hydrophotometer has a precision of +/- 10% and an accuracy of +/- 2%. For usSEABED, data were digitized, visually compared to the source 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: No estimate made for original data. For inclusion into usSEABED, all textural data in the report were included; Petrographic and clay mineral analyses will be included at a later date. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Navigation during all cruises was by Miniranger and provided nominal position accuracy of +/- 50 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Water depth determination probably by 3.5 kHz profiling systems. Subsample depths given as nearest centimeter. Lineage: Process_Step: Process_Description: Core samples and subsamples taken aboard ship were sealed to minimize dehydration and were stored at 3°C until the analytical phase began. Sample were first treated with 30% H202 to remove organic material, then placed in a 10-ml solution of 30% H202 and 50-ml of H20 and allowed to stand for 24 hr or until oxidation ceased. Excess liquid and salt were removed by repeated washes with distilled water. Following this treatment, the samples were separated into gravel, sand, silt, and clay using wet-sieves and/or centrifuge techniques. Grain-size analyses were made by first determining the dry-weight percent of the gravel, sand, silt, and clay size fractions. The size distributions of sand fraction ( -1.0 to 4.0 phi) were then determined using a 2-m Rapid Sediment Analyser (RSA) (Thiede, et al., 1976). The size distribution of the silt and clay fractions (<4.0 phi) were determined using a calibrated hydrophotometer (Jordan, 1977; Jordan, et al., 1971. The grain-size data were used to calculate sediment textural parameters by the graphic method of Folk (1974). The textural parameters include percent sand, percent silt, percent clay, median, mode, graphic mean, inclusive graphic standard deviation, and inclusive graphic skewness. The values of these textural parameters for the surface samples are given in Table 2.
