It comprises Innomar SES-2000 subbottom profiler data. The data was recorded using electronic beamforming induced by a sawtooth function adding a sweep of -8°to8° to the motion data roll angle. A Stonex S9i RTK GNSS receiver was used, providing a RTK position every 0.1 s. The echosounder data covers a region around a 1978 recorded unknown shipwreck.
