Abstract:
Raw multibeam bathymetry data were recorded on RV METEOR during M78_3A using Kongsberg EM120 multibeam echosounder. The cruise took place between 19.05.2009 - 13.06.2009, (Montevideo - Montevideo, Uruguay) in the Atlantic Ocean. Data were recorded throughout the whole time spend outside EEZs with an approximate average depth of around 2500m.
To enhance MBES data accuracy, real-time measurement by SV-Profiler at transducer depth were directly applied during acquisition with SIS Seafloor Information System. There are no extra SVP files provided in this publication.
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.
Data acquisition and provision were accomplished to support sediment transport examination at the southwestern Atlantic continental margin off Uruguay and Northern Argentinia.
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.
Data publication is 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/).
