Purpose: Profiles of resistivity on the shoreline will be used to assess the potential for terrestrial groundwater intrusion on the reef and the sources and fate of these water masses.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: No formal attribute accuracy tests were conducted. Logical_Consistency_Report: Data fall within expected ranges. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the metadata for each part of this data release carefully for additional details. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A formal accuracy assessment of the horizontal positional information in the data set has either not been conducted. Latitude and longitude were only measured at the beginning and ending of the ERT transect, and as such, horizontal coordinates are not available at each transect point. However, the transect is a straight line, and the distance of each point along the transect was measured by tape measure. The stated accuracy of the GPS unit used to determine the beginning and ending of the ERT transect is +/- 5m. Lineage: Process_Step: Process_Description: Surface-based 2D Electrical Resistivity Tomography (ERT) surveys were conducted alongshore at the shoreline for one week in late July and early August of 2016 using a SuperSting R8 (AGI, Austin, Texas, USA) and cable with 56 electrodes at 2-m spacing. A dipole-dipole (DD) array was used with a max n-spacing of 7. Process_Date: 20160804 Process_Step: Process_Description: Resistivity data were processed using the manufacture’s software, AGI Earth Imager, and data exported to comma-delimited text files.
