Abstract:
Raw multibeam bathymetry data were recorded on RV METEOR during M156 using Kongsberg EM710 multibeam echosounder. The cruise took place between 2019-07-03 - 2019-08-01, (Mindelo-Mindelo, Cape Verde) in the Atlantic Ocean. Data were recorded within Cabo Verde & Mauritanian EEZ and throughout the whole time spend outside EEZs with an approximate average depth of around 2000m.
To enhance MBES data accuracy, CTD casts were made in the working area prior to each MBES survey using CTD rosette to raytrace beams with the obtained sound velocity profiles (SVP). During transits, real-time measurement by SV-Profiler at transducer depth were directly applied during acquisition with SIS Seafloor Information System.
Data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors can be expected due to the lack of proper SVP.
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. Ancillary sound velocity profiles (SVP) files from the cruise are archived at the BSH, thus SVP files are added to this dataset.
Data acquisition and provision were accomplished within work package 2 of the EU Horizon 2020 project iAtlantic- Integrated Assessment of Atlantic Marine Ecosystem in Space and Time (https://www.iatlantic.eu/) IceAge project.
