Многолетние изменения термохалинных характеристик Балтийского моря

Changes of temperature and salinity for the Baltic Sea in general and for the Slupsk Trough and the Gdansk Depression in particular were described, according to the World Ocean Atlas (WOA 13) and Helcom data, and using the observation data. The main purpose is to study the inflows of the North Sea waters (or Major Baltic Inflows – MBI), influencing the deep water layer formation in the Baltic Sea. The conditions of the seasonal cold interlayer (CIL) waters formation were analyzed. The parameters of the layer and MBI waters were correlated with the North Atlantic Oscillation (NAO) Index.
