Multibeam bathymetry raw data (Kongsberg EM710 entire dataset) of RV METEOR during cruise M122

DOI

Multibeam bathymetry raw data using the ship's own Kongsberg EM 710 multibeam echosounder was almost continuously recorded during RV METEOR cruise M122. Data was recorded on 25 days between 2015-12-30 and 2016-01-23. This dataset contains a survey towards the coast of Namibia & Angola. The approximate average depth of the entire dataset is around 400m.The data are archived at the Federal Maritime and Hydrographic Agency of Germany (Bundesamt fÃür Seeschifffahrt und Hydrographie, BSH) and provided to PANGAEA database for data curation and publication. Ancillary sound velocity profiles (SVP) files from the cruise are archived at the BSH, thus SVP files are added to this dataset. Also data analysis of the multibeam raw data revealed that SVP has been changed during the survey.This publication is conducted within the efforts of the German Marine Research Alliance in the core area 'Data management and Digitalization' (Deutsche Allianz Meeresforschung, DAM)Data are unprocessed and therefore contains incorrect depth measurements (artifacts) without further processing. Note that refraction errors can be expected due to the lack of proper SVP. Overall, it appears that the data quality is rather good since the gridded hillshade data showed relatively few obstacles. Data acquisition has been monitored at all times during surveying.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).

These data should not be used for navigational purposes.Data publishing was realized by Daniel Damaske, MARUM - Center for Marine Environmental Sciences (University Bremen).
