Ziel der Reise / Objectives of Cruise:
On January 7, 2012 'Polarstern' left Capetown for the Antarctic cruise ANT-XXVIII/3. Major objectives were investigations in different biogeographic provinces of the Southern Ocean. Numerous hydrographic stations were carried out along a transect and within two grids. The route led southwest until 44?S and 10?W. A transect with hydrographic stations was conducted along 10?W until 53?S crossing the Subantactic Front, the Antarctic Polar Front and the Southern Polar Front. During the transect the first large benthos station took place at 52?S. Passing stations at 52?S, 8?W and 52?S, 12?W the route led to the region around 51?12`S, 12?40`W where we sampled a grid of stations for more than 2 weeks. After a half-day visit at Grytviken (South Georgia) - combined with a visit at the station of the British Antarctic Survey - we steamed to the northwest of South Georgia. In the region around 50?S, 38?W a grid of 30 stations at intervals of 24 nautical miles was carried out. In the centre of a cyclonic mesoscale eddy at 49?40`S, 38?16`W a detailed sampling of the water column was performed in 5000 m water depth using all devices available. For the benthos sampling in this biogeographic province we chose a station at the southwest corner of the grid at 50?48`W, 39?24`W. The local water depth of 4100 m allows comparisons with prior benthos stations. During the whole cruise oceanographic and chemical measurements as well as investigations of the plankton and the deep-sea fauna were carried out. The station work was finished at March 7 and 'Polarstern' sailed to Punta Arenas, Chile, where the cruise ended on March 11, 2012.
