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.
The Bulletin of Marine Science is dedicated to the dissemination of high quality research from the world's oceans. All aspects of marine science are treated by the Bulletin of Marine Science, including papers in marine biology, biological oceanography, fisheries, marine affairs, applied marine physics, marine geology and geophysics, marine and atmospheric chemistry, and meteorology and physical oceanography.
