Abstract:
Raw multibeam bathymetry data were recorded on RV Maria S. Merian during MSM19/3 using a Kongsberg EM710 multibeam echosounder. The cruise took place between 01.12.2011 – 22.12.2011 (Cape Town – Cape Town, South Africa) in the Southern Atlantic. Data were recorded throughout the whole time spend outside EEZs with an approximate average depth of around 4000m.
There is no information about sound velocity corrections made.
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.
During cruise MSM19/3 comprehensive bathymetric mapping and hard rock sampling has been carried out at the Agulhas Ridge, adjacent basement highs, and the Discovery Rise.
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/).
