| Abstract |
During the third leg of the "European Polarstern Study" (EPOS leg 3) in the austral summer season 1989, benthic macrofaunal communities were sampled from the Elephant Island area (61-degrees-southern latitude) and from Kapp Norvegia (71-degrees-southern latitude) to Halley Bay (75-degrees-30' southern latitude) using a commercial bottom trawl and an Agassiz trawl. Thirty-six trawl samples from a depth range of about 200-2,000 m were considered, with most of the samples being from the shelf and upper slope. Multivariate analysis techniques (clustering and TWINSPAN) discriminated between an eastern and a southern community in which parallel subgroups can be distinguished at increasing distance from the ice shelf. |
