Abstract:
Raw multibeam bathymetry data were collected using the ship's own Kongsberg EM120 multibeam echosounder during the RV METEOR cruise M76/1a. The cruise took place between 2008-04-12 and 2008-04-24 (Cape Town, South Africa – Walvis Bay, Namibia). Bathymetric mapping aimed to explore the Namibian continental slope, especially the large seafloor depressions. 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. No sound velocity profiles (SVP) files from the cruise are archived at the BSH, thus no SVP files are added to this dataset. Data are unprocessed and therefore contain incorrect depth measurements (artifacts). Data can be processed e.g. with the open source software package MB-System (Caress, D. W., and D. N. Chayes, MB-System: Mapping the Seafloor, http://www.mbari.org/products/research-software/mb-system/, 2022).
