A team of scientists is currently on board the research vessel METEOR. The target area is the southern subpolar North Atlantic, where moorings of a deep-sea observatory are to be recovered and the data subsequently evaluated. They shall serve to extend existing time series of the flow components of the so-called Atlantic Meridional Recirculation Circulation (AMOC) and water mass properties. The time series are an important reference for climate models. The expedition is led by Dagmar Kieke from the Institute of Environmental Physics at the University of Bremen and MARUM.
