PROPERTIES OF HYDROLOGICAL AND HYDROCHEMICAL CONDITIONS IN THE SOUTH BALTIC DURING THE IGY,

Abstract

The period of IGY embranced the culmination of freshening cycle of the Baltic Sea (1957-1958) and the beginning of a new salinity cycle (1959). In 1958, that is in the period of the maximum stagnation development of the waters of the Southern Baltic, the minimum salinity content were observed. The phosphate the silicic acid amount was very large. The salinity and temperature of the total water column were the lowest over the last 15 years. In 1959 there was a complete renewal of the bottom layers of the Southern Baltic, which was followed by sharp increase of salinity, temperature, dissolved oxygen and decrease of biogenetic elements. These processes occurred as a result of the inflow of saline waters of the north seas. In the next five years, large development of western circulation, increase of the river discharge, decrease of the icing and some increase of salinity of the bottom waters of the Southern Baltic must be expected.
