High Frequency GPR data for Thazhamkuda fan, SE India

Eight Ground Penetrating Radar profiles were collected across the Cyclone Thane (2011) washover fan preserved at Thazhamkuda, near Cuddalore on the southeastern coast of India. The GPR data were collected with the 1000 MHz shielded Sensor and Software Pulse Echo antennas. The antennas were uniformly 15 cm apart, the electromagnetic pulse time window was set to 25 ns and the data stacked 4 times. Electromagnetic pulses were emitted and recorded at 1 cm intervals. Topography was collected using a Trimble differential Global Positioning System (dGPS) that was ground-truthed from a surveyed height at a local train station. Due to the relatively flat terrain across the fan, dGPS heights were collected at approximately 10 m increments or where significant breaks in slope occurred. The dGPS measurements have a horizontal accuracy of approximately 1.5 cm and a vertical accuracy of 4 cm. Only the raw GPR and topography data are contained here and processed data (including processing steps) are presented in a forthcoming publication.
