Seasonal and Geographic Variations in Sea Ice Community Structure of the Weddell Sea, AntarcticaSea ice cores were collected from 22 stations. Winter values for chlorophyll a measured per 10 cm segment of drilled ice core ranged between 0 and 49 μgl. (mean 3.4) during July to September and between 0 and 450 μgl. (mean 7.6) during October to December, while mean summer values were considerably

Seasonal Variation in Ice Algal Assemblages in the Fast Ice Near Syowa Station in 1983/84 occurred in April–June and October–November; the largest (125 mg chlorophyll . m.) occurred in mid-November at a site with moderate snow cover. Chlorophyll was most highly concentrated in the bottom of the ice, where the diatoms . were dominant. The chlorophyll concentration within the ice develope
