Multibeam bathymetry raw data (EM 120 echosounder entire dataset) of RV METEOR during cruise M68/2

Raw multibeam bathymetry data were recorded on RV Meteor during M68/2 using a Kongsberg EM120 multibeam echosounder. The cruise took place between 6.6.2006 – 9.7.2006 (Recife (Brazil) – Mindelo (Cape Verde)) in the Tropical Atlantic. Data were recorded throughout the whole time spend outside EEZs as well as within the Brazilian EEZ with an approximate average depth of around 3500m.

There is no information about sound velocity correction 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 M68/2 an intensive mooring program was carried out to investigate circulation and variability in the Tropical Atlantic. This program particularly consisted of the recovery of two equatorial current meter moorings at 35°W and 23°W.

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/).
