Signy Island as a Paradigm of Biological and Environmental Change in Antarctic Terrestrial Ecosystemencing biological processes. Central to these changes is the present climatic warming being experienced, especially in the more northerly regions, which is causing substantial recession of glaciers and ice fields and creating new surfaces on which biota may become established.

Seasonal and Regional Variation in the Pelagial and its Relationship to the Life History Cycle of Krotrophic communities of warm, nutrient-depleted waters. Results of recent sediment trap moorings show that the Antarctic oceanic pelagial behaves as a highly efficient retention system as losses due to sinking particles are exceptionally low. We show that the distinction into “new” and “regenerating作者: 表狀態(tài) 時間: 2025-3-23 11:42
Primary Production and Consumption in McMurdo Sound, AntarcticaMcMurdo Sound environment is briefly described, covering aspects such as bathymetry, sea ice development and breakout, and the hydrological regime.

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.
