Preliminary results of research activities of RV Evrika in the Scotia Sea in January-March 1988
In 1987/88 a multi-disciplinary survey was conducted of the Scotia Sea and adjacent waters, accompanied by regular trawlings with an Isaac-Kidd trawl. The waters off South Georgia in particular were surveyed twice. Research activities are part of the program implemented in areas of the Atlantic Sector of the Southern Ocean identified for monitoring by CCAMLR. During the observation season the zonal drift of waters of the Antarctic Circumpolar Current and Second Frontal Zone became stronger, causing the krill to drift eastwards. Krill concentrations were observed in the waters to the southeast of South Georgia where relatively small crustaceans of less than 35 mm dominated. In the east Scotia Sea a higher abundance of primary production was registered. The analysis of data on phytoplankton, zooplankton and krill (biological parameters) is now under way.
