Multibeam data were collected during R/V Polarstern cruise ARK-XIII/2. Systematic profiling and data recording was executed west of Svalbard and was supervised by three hydrographers. Data are unprocessed and may contain outliers and blunders. Therefore the data should not directly be used for grid calculations and charting projects but need to be edited furthermore. The dataset consists of 2 files in ATLAS ascii multibeam format including 'record control words' (*.dux) which are compressed with GZIP to size of 20.4 MB. Atlas DUX data files can be processed using the open source software package MB-System (http://www.ldeo.columbia.edu/res/pi/MB-System/). Contact mailto:infobathy@awi.de for data access.
