Ziel der Reise / Objectives of Cruise:
The SeASOM cruise POS 526 from 23 July (Bergen in Norway) to 11th August 2018 (Kiel, Germany) was split in two legs with a stop-over in Hirtshals, Denmark on 1st August. The first part visited the Dogger Bank seep site in the Dutch EEZ. Investigations of gas fluxes of dissolved and free methane (bubbles) were the scientific focus of several different studies. SeASOM was in this respect also applying new technology and was run as part of the Helmholtz infrastructure project MOSES, a new Wave Glider with gas analysing capabilities, the new AUV ANTON as well as a sophisticated gas analysing system from USGS were used to shade light into gas fluxes from the seafloor through the water and into the atmosphere. The second leg focussed on ecological and technical studies in the Tisler Reef area in Norway. Here the distribution of different fauna and their relation to high resolution bathymetry and bottom current information was the focus of the research. Again technical trails were part of the research, AUV ANTON was used for the first time in difficult terrain and showed its capabilities to dive down to 400m in Oslo Trough. Submersible JAGO was equipped with a stereographic camera system for highly detailed photogrammetric analyses and for the first time it was possible to log and see the location of JAGO inside the submersible in real time, using underwater navigation and data communication technology of MOSES. In summary the cruise was very successful, ample of good data have been acquired and the cooperation between science and ship crew went smooth and professional.
