This folder contains a shapefile that can be opened in ESRI ArcGIS software that displays shore-perpendicular chirp tracklines. The tracklines are linked to a data table that displays the volume of Holocene and shoreface sediment units at each shore-perpendicular chirp line transect, with volume displayed in cubic meter per meter (m^3/m). This shapefile provides location information for Table 2 for the accompanying Open File Report. For more details on interpretation and calculation methods, please see the Open File Report.
