Two of the grab samples were sieved and analyzed for grain size distributions. 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.

Online_Linkage: https://doi.org/10.1016/j.sedgeo.2007.05.016 Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: No formal accuracy assessment was performed on the sieved sediment samples. 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. Where values could not be computed due to a lack of convergence in the image processing algorithm, fields 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 grab samples were collected at 158 locations in the foreshore and on the beach at depths between 0.5-1 cm. 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.
