Beschreibung:
Raw multibeam bathymetry data were recorded on RV Meteor during M62/4 using an Atlas Hydrosweep DS2 multibeam echosounder. The cruise took place between 2004-09-30 (Mindelo) – 2004-11-04 (Recife) in the Southern Atlantic. Data were recorded in international waters outside EEZs as well as within the Ascension Island EEZ with an approximate average depth of around 1500m.
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.
The aims of M62-4 were to investigate the tectonics and structure of the Ascension transform inside-outside corner pair and to constrain the processes of segmentation occurring at the Mid-Atlantic Ridge just south of the Ascension FZ.
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/).
