Abstract:
Multibeam bathymetry raw data using the ship's own Kongsberg EM 122 multibeam echosounder was almost continuously recorded during RV METEOR cruise M86/1c. Data were recorded on 11 days between 2011-12-12 and 2011-12-23. The approximate average depth of the entire dataset is around 3700m.
The cruise took place between 2011-12-06 and 2011-12-23 in the eastern North Atlantic Ocean. The main aim of this cruise was the calibration of the multibeam systems of RV METEOR at Gettysburg seamount.
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. Ancillary sound velocity profiles (SVP) from the cruise are archived at the BSH, thus added to this dataset. Data analysis of the mulitbeam raw data reveled that SVP has been changed on several occasions during the cruise.
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 may contain incorrect depth measurements (artifacts) without further processing.
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/, 2021).
