Description
Summary:Leg 4 of POLARSTERN cruise 29 was dedicated to the eastern Scotia Sea which is part of the antarctic South Atlantic Ocean. Main goal were investigations on fluid and gas circulation of the Sandwich Microplate. Recent investigations have proved hydrothermal and volcanic activities at the backarc spreading center. In contrast active fluid seepage in the forecarc between the island arc and deep sea trench was completely unknown and therefore a target of investigation on this expedition. Besides this, marine geoscientific work south of Falkland and around South Georgia was carried out and provided new insights to shallow gas seepage on the shelf of South Georgia.
