Abstract

Ten marine surface samples were collected in Potter Cove, King George Island, Antarctica in austral summer 2010 from water depth from 25 up to 114 m and were counted for recent benthic foraminifera. 27 benthic species were found, which consist of 66,7% calcareous and 33,3% agglutinated forms. The highest amount of foraminifera per gram was developed at a middle water depth and a middle distance to the glacier. Three Zones with foraminiferal communities were recognized, which characteristics like diversity and occurrence were con- trolled by different environmental factors. The most important influencing factor seems to be the water depth and the distance to the glacier in contrast to the sediments, which seem not to influence the foraminiferal distribution. A positive correlation is also discovered be- tween diatoms and foraminifera, so the more foraminifera the less diatoms were found.
