Weekly Reports Polarstern
The Expedition PS115/1 Tromsø - Longyearbyen
Cruise PS115.1 of RV Polarstern headed by BGR leads to the northern North Atlantic off Greenland. Scientific goal of the research activities is to acquire new geophysical data on the geological structures below the seafloor in this particular region. This information is of special importance to reconstruct the plate tectonic history of the Arctic over the last 60 Million years, which is one of the scientific goals of project GREENMATE. Besides geophysical surveying it is also planned to extract seafloor sediment samples. The subsequent investigations include geochemical analysis to understand the natural carbon circulation and to deduce the palaeoclimate evolution in the Arctic. The research activities also include helicopter operations to sample rock material from near coastal outcrops. The international team of 48 scientist from countries include among others researcher teams from the Alfred-Wegener-Institute Helmholtz Centre for Polar and Marine Sciences, Bremerhaven, the GEOMAR Helmholtz Centre for Ocean Research, Kiel, the Helmholtz Centre for Environmental Research, Leipzig, and the University of Bremen.
