Raw multibeam bathymetry data were collected using the ship's own SIMRAD EM710 multibeam echosounder during the RV METEOR cruise M73/1 WestMed. The cruise took place between 2007-07-21 and 2007-08-12 (Cadiz, Spain – Genoa, Italy).During leg M73/1, EM710 data were collected in the EEZ of France between 2007-07-25 and 2007-08-06. These data are of worse quality than the EM120 multibeam bathymetry data collected on the same cruise, and might have been acquired in a test mode.The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt für Seeschifffahrt und Hydrographie, BSH) and provided to PANGAEA database for data curation and publication. No ancillary sound velocity profiles (SVP) files from the cruise are archived at the BSH, thus no SVP files are added to this dataset.Data are unprocessed and therefore 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.Chief scientist has approved this data submission and confirmed that the permissions to collect bathymetry data within the respective EEZ have been obtained.This data submission was prepared by Evgenia Bazhenova (MARUM).
