Description:
On 26 July 2018, we collected apparent resistivity data (ohm-m) in a sub-aquatic permafrost environment north of the Alaskan coastline at Drew Point in the United States. The data was collected with an IRIS Syscal Pro Deep Marine resistivity system that was equipped with a GPS and an echo sounder to record water depths. The geoelectric cable had an electrode separation of 5 m and the electrodes were arranged in a reciprocal Wenner Schlumberger array. The offset between the first electrode and the boat was 6.6 m. The main goal of the survey was to map the depth to the top of ice-bearing subsea permafrost. The survey started approximately 850 m offshore and ended close to the coastline.
