Comment:
In July 2017, apparent resistivity data were collected with an IRIS Syscal Pro Deep Marine system and floating electrodes. The device was equipped with a GPS and an echo-sounder to record the position of the boat and the water depth for all measurements. Each row of data includes the position and elevation (in metres) of the two current electrodes (C1 and C2) and the two potential electrodes (P1 and P2), as well as the apparent resistivity (in ohm-meters). Another dataset https://doi.pangaea.de/10.1594/PANGAEA.895883 shows the latitude and longitude for each survey position and the water depth (in metres).
Apparent resistivity data is available until a distance of 298 m and bathymetry is available until a distance of 371 m.
