Abstract:

There are few zooplankton investigations in the ice-covered sea around the Antarctic continent compared to those in the Antarctic open waters. In 1982, zooplankton sampling was carried out at one station at a depth of 675 m in the fast ice area near Syowa Station, Antarctica, as a part of the Japanese BIOMASS programs. A total of 13 vertical hauls from 660 m to surface were made at 2–3-week intervals between May (late autumn) and December (early summer). Average biomass of zooplankton was 13.5 g wet weight per 1,000 m3, with the maximum of 25.5 g in August. Copepods, chaetognaths and ostracods constituted major components of the zooplankton community occupying more than 90% of all the zooplankters. Abundance and composition of the zooplankton community changed seasonally and three different phases were demarcated.
