Protozooplankton in the Weddell Sea, Antarctica: abundance and distribution in the ice-edge zone

Protozooplankton were sampled in the ice-edge zone of the Weddell Sea during the austral spring of 1983 and the austral autumn of 1986. Protozooplankton biomass was dominated by flagellates and ciliates. Integrated protozoan biomass was 20%. Bacterial biomass exceeded protozooplankton biomass at ice...

Description
Summary:Protozooplankton were sampled in the ice-edge zone of the Weddell Sea during the austral spring of 1983 and the austral autumn of 1986. Protozooplankton biomass was dominated by flagellates and ciliates. Integrated protozoan biomass was 20%. Bacterial biomass exceeded protozooplankton biomass at ice covered stations but in open water stations during the fall, protozooplankton biomass reached twice that of bacteria in the upper 100 m of the water column. The biomass of different protozoan groups was positively correlated with primary production, chlorophyll a concentrations and bacterial production and biomass.
