Phytoplakton and Zooplankton Standing Stocks and Downward Flux of Particulate Material around Fast Ice Edge of Lutzow-Holm Bay,Antarctica
P(論文) 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.
