Abstract
Multibeam data were collected with RV Polarstern during parts of the MOSAiC polar drift on cruise PS122/1. Data acquisition was unmonitored during the survey. Multibeam sonar system was Teledyne/Atlas Hydrosweep DS3. SVP profiles were not applied during acquisition, yet CTD profiles were acquired by other working groups on board. Multibeam data are unprocessed and may contain outliers and blunders and should not be used for grid calculations and charting projects without further editing. The raw multibeam sonar data in Teledyne/Atlas multibeam processing format (.asd) were recorded with Teledyne/Atlas Parastore software as well as Teledyne Reson format (.s7k) in Teledyne PDS. Raw data files can be processed using software packages like CARIS HIPS/SIPS.

Initial commit
Knut and Alice Wallenberg Foundation (KAW) and Swedish Research Council (VR) financed the Oden multibeam system and the installation was financed by the Swedish Maritime Administration. The Oden expeditions were organized by the Swedish Polar Research Secretariat. This Mapping Repository is a part of the Bert Bolin Centre for Climate Research data archive.
