Raw bathymetry data were collected using the Kongsberg EM2040 multibeam echosounder installed on the MARUM AUV SEAL during the RV POSEIDON cruise POS500 Ligurian Slope AUV mapping, gravity coring and seismic reflection (LISA). The cruise took place between 2016-05-25 and 2016-06-09 (Catania, Italy - Malaga, Spain), aiming to investigate the controls of slope failure and submarine landslide processes off the Nice International Airport focusing on the 1979 landslide and resulting tsunami. The high-resolution AUV echosounder data were complemented by the ship's bathymetry, multi-channel seismic survey and gravity coring. No sound velocity profiles (SVP) were collected during the cruise. Data are unprocessed and contain incorrect depth measurements (artifacts). Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2022).

These data should not be used for navigational purposes.This data submission was prepared by Evgenia Bazhenova (MARUM).
