Ziel der Reise / Objectives of Cruise:

During this short cruise, we explored the potential of acoustic echo sounding techniques (wideband single-beam and multibeam systems) for the quantitative investigation of turbulence and other small-scale processes in the water column. These activities were embedded in the research project ?Four dimensional Research applying Modeling and Observations for the Sea and Atmosphere" (FORMOSA), funded by the German Leibniz-Association (WGL) in the framework of the national funding line "Cooperative Excellence". The cruise took place in May 2021 in the Kattegat region and the western Baltic Sea (Arkona Basin). Our activities focused on the mixing of salty North Sea waters and brackish outflow waters from the Baltic Sea in the Kattegat region with the help of turbulence microstructure and acoustic observations. Measurements were conducted by scientists from IOW in collaboration with project partners from Stockholm University (Sweden) and an additional engineering group from Rostock University (Germany).
