Central Baltic deep water stagnation

The Institute of Marine Research and later the Baltic Sea Research Institute in War-nemiinde were laigely involved in investigations of the analysis of specific inflows of highly saline water and the study of the water renewals in the central Baltic, as well as on the stagnation periods following these events in the central Baltic deep water.

The first deep basin downstream of the entrance sills is the Bornholm Basin (Fig. 10.1). This basin has a maximum depth of more than 90 m and is separated from the next downstream basin by the Slupsk Sill (sill depth 60 m). The buffering properties of the Bornholm Basin play an essential part for the effectiveness of MBls in other central basins. The thermohaline conditions in the Bornholm Basin are also considerably important for the evolution of stagnation in the central Baltic deepwater. In general, there is a frequent inflow of lower amounts of highly saline water that penetrates across the sills into the ArkonaBasin during each baroclinic or weak barotropic inflow event. This water is trapped into the...
