The benthic fauna was investigated during the expedition ANT-XXIV/2 (2007/08) in relation to oceanographic features, biogeochemical properties and sediment characteristics, as well as the benthic, pelagic and air-breathing fauna. The results document that Maud Rise (MR) differs distinctly from surrounding deep-sea basins investigated during previous Southern Ocean expeditions (ANDEEP 2002, 2005). Considering all taxa, the overall similarity between MR and adjacent stations was low (~20% Bray-Curtis-Similarity), and analyses of single taxa show obvious differences in species composition, abundances and densities. The composition and diversity of bivalves of MR are characterised by extremely high abundances of three species, especially the small sized Vesicomya spp. Exceptionally high gastropod abundance at MR is due to the single species Onoba subantarctica wilkesiana, a small brooder that may prey upon abundant benthic foraminiferas. The abundance and diversity of isopods also show that one family, ... : Supplement to: Brandt, Angelika; Bathmann, Ulrich; Brix, Saskia; Cisewski, Boris; Flores, Hauke; Göcke, C; Janussen, Dorte; Krägefsky, Sören; Kruse, Svenja; Leach, Harry; Linse, Katrin; Pakhomov, Evgeny A; Peeken, Ilka; Riehl, Torben; Sauter, Eberhard-Jürgen; Sachs, Oliver; Schüller, M; Schrödl, M; Schwabe, E; Strass, Volker H; van Franeker, Jan Andries; Wilmsen, Markus (2011): Maud Rise - a snapshot through the water column.
