Biological investigations during the cruise of M/V POLARSIRKEL were part of the scientific programme accompanying the pre-site survey. On 125 biological stations, 272 hauls on plankton and fish were carried out. 24 fish species had been determined, most of them had previously not been found in the Weddell Sea. The investigations also comprised a count of birds and seals. The fate of fluorine in the food chain and cadmium analyses were subject of the biochemical investigations.
