Abstract

In the 61st cruise of the R/V Akademik Ioffe (June 28–July 12, 2022), complex oceanographic survey was carried out in the Russian sectors of the South-Eastern Baltic Sea and the Gulf of Finland. In the conditions of long-term absence of major inflows of North Sea waters, hypoxia and anoxia continue to develop in deep waters. In the eastern part of the Gdansk Deep, a contourite drift was identified for the first time, formed during the Littorina phase of the Baltic Sea. Together with the Kant Baltic Federal University, complex study was carried out on the offshore site of the Kaliningrad carbon polygon and the V International Summer School “Coastal zone of the sea: research, management and prospects” was held.
