  Description:
    Abstract: Offshore and Beach samples were collected between August 1994 and August 1999. Grainsize, Insoluble Residue, Composition and Abrasion data on this CDROM are presented in Microsoft EXCEL 97/98 and 5.0/95 Workbook (.xls) format and comma separated value (.csv) format and in HTML format.

    Purpose: This data set is intended for scientific research of beach and offshore sand deposits composition and volume changes.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: The data have been thoroughly analyzed for gross inaccuracies. A few beach samples were taken on the beach between the edge of the beach and the toe of the beach, these samples were not annotated with a point number and were assigned a point number later. The actual location of these points may vary by several meters one way or the other along the line.

  Logical_Consistency_Report: Grainsize analysis was done using methods from Carver (Carver, Robert E., Procedures in Sedimentary Petrology, 1971).Composition Analyses were done using a binocular microscope. Up to 500 grains per sample over -.5 phi in size were identified and counted. A few samples did not have enough viable grains (large enough) for analysis and were not counted. In the GIS section, a few beach locations did not have any location information and were left out of this section.
