A considerable difference in the krill biomass between Antarctic spring and summer was recorded. Initially observations were conducted close to Elephant Island, in the period just after the retreated of compact ice cover. Krill then aggregated only in swarms, the density of which frequently exceeded 100 t nM-2 . In the region of Polygon I (30—31 October 1986) the total estimated biomass was 26899 t, in the region of Polygon II (6—10 November 1986) it was 25827 t. Investigations were repeated in January 1987 obtaining 112372 t in the Bransfield Strait and 390309 t in the region of Elephant Island. The results are presented in tables and maps.}, type={Article}, title={Biomass variability of krill in the South Shetland Islands region (BIOMASS III, October 1986—January 1987)}, URL={http://so.czasopisma.pan.pl/Content/111279/PDF-MASTER/1988_2-3_327-338.pdf}, keywords={Antarctica, krill stocks, BIOMASS III}, }
