The multi-disciplinary project Eddy Pump was designed to study processes which exert a control on the physical and biological pumps of carbon in the Southern Ocean. The data for Eddy Pump were collected 2012 during Polarstern Cruise ANT-XXVIII/3, which started January 7 in Cape Town and ended March 11 in Punta Arenas. The study sites visited were selected in order to represent different biogeographic regimes found along the Antarctic Circumpolar Current (ACC) in the Atlantic sector: 1. the central ACC with its regular separation in different frontal jets (investigated by a meridional transect along 10°E), 2. a transient months-long lasting large-scale bloom that occurred west of 10°W adjacent to chlorophyll-poor waters to the immediate east, and 3. the region in the wake of South Georgia, which regularly features a dense bloom presumably stimulated by iron released from that island and its shelf. After presenting an overview of the obtained first results we will put up for discussion possible explanations for the observed patterns.
