The different locations (termed W1, W2, and W3) represent three different slope-failure modes. Sediment grab samples for most bluff locations were collected in August 2009, while sediment samples from the bluff at site W3 and multiple foreshore locations were collected in September and October of 2009. Two of the grab samples were sieved and analyzed for grain size distributions (7 classes ranging from 0.06 to 0.72 mm). The grain size distribution of the remaining samples was determined from referenced photographs of collected samples taken in the lab following the method of Barnard and others (2007) using two-dimensional spectral decomposition of sediment images (Buscombe and others, 2010). Results of sieved samples were used to verify mean grain-size values obtained with the image processing algorithm. Data are available in a single csv file. Purpose: Data were obtained to provide baseline information and to support the development of numerical models for assessing past and future coastal hazards. These data are intended for policy makers, resource managers, science researchers, students, and the general public. These data are not intended to be used for navigation.

Beach (foreshore) sediment grain sizes derived from referenced photographs are estimated to be accurate within 23 percent of the reported values, based on comparisons between sieved and image-processed samples. Logical_Consistency_Report: All data fall within expected ranges. Fields where data is not applicable have been filled with -9999 values. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. Sediment sample locations were obtained with hand-held GPS units and are estimated to be accurate to within 4 meters. Lineage: Process_Step: Process_Description: Sediment was sampled on three bluffs and the bluff foreshore at depths ranging from 0.01-2.5 m by hand-auguring and manual trenching. Process_Date: 20091004 Process_Step: Process_Description: Sediment grab samples were sieved and analyzed for grain size distributions using 6 sieves with screen sizes (in units of phi): -1,0,1,2,3,4. Mean grain sizes of remaining samples were computed using the MATLAB-based DGS toolbox from referenced photographs of collected samples taken in the lab following the methods of Barnard and others (2007) and using two-dimensional spectral decomposition of sediment images as described in Buscombe and others (2010). Results of sieved samples were used for verification of mean grain size values obtained with the image processing algorithm.
