Abstract
The occurrence of zooplankton species, indicating a salinewater influx from the North Sea into the Baltic Sea in 1972, is described. Particular attention is paid to 8 species so far unknown in this region (Ectopleura dumortieri, Rosacea plicata, Tomopteris kefersteini, Aetideus armatus, Centropages typicus, Eucalanus elongatus, Metridia lucens, Electra pilosa). The appearance of these zooplankters in the Southern Baltic Sea is discussed in relation to the hhdrographic changes taking place in this area in 1972. Based on these data, assessments are made regarding the intensity of dynamic exchange processes in the Baltic and North Atlantic waters in 1972.
