This is the raw multibeam data collected during cruise MSM109 using the hull-mounted Multibeam Echosounder Kongsberg EM122 (2 by 2 degrees with ice window). This data collection includes the transits from Tromsø to the Svalbard region, the surveys, and the transit back to Reykjavík. The swath width was set to 130 degrees. New Sound Velocity Profiles are inserted into the acquisition software after every CTD station. A Surface Sound Velocity sensor was used in real time to correct the data transmission. Depth mode was set to auto. Data was logged using the .ALL format from Kongsberg Maritime. Water Column Data was also recorded and integrated into PANGAEA as separate dataset.

These data should not be used for navigational purposes.
