Phyto- and zooplankton standing stocks in the fast ice and in the water column under the ice and downward flux of particulate material through the water column were investigated in Liitzow-Holm Bay, Antarctica, during the austral summers, i.e., in January 1977 and February 1979. Chlorophyll a standing stock integrated through the ice was 0.38-0.80 mg/m^2 and that in the water column beneath the ice down to 150 m was 3.06 mg/m^2. Microdistribution of zooplankton beneath the ice was observed by the pumping collections and the dense populations were found just beneath the ice. Zooplankton density was in a range of 12-60 indiv/m^3 and the zooplankton stocks integrated through the 150 m water column ranged from 6000 to 7675 indiv/m^2. By the sediment trap operation, the fecal materials were found to comprise a large proportion of the collected particles. The maximum daily vertical flux of particulate organic carbon (POC) was found at the 100m depth (103 mg C/m^2/day) and concentration of POC in the water column was in a range of 24-56 mg C/m^3. These data on standing stocks of phyto- and zooplankton and vertical flux of POC in the icecovered Liitzow-Holm Bay were compared with those in the other sea areas. |
