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.

Week 6: From East Svalbard towards the deep Arctic Ocean

[04. July 2017] 

The past week we started in the marginal sea ice zone east of Svalbard, and then set course north into the central Arctic Ocean.The marginal sea ice zone was mostly covered with decaying sea ice and some larger ice-free areas. On this side of Svalbard we saw a lot more wildlife than in the westerly part. A large number of birds are constantly circling around the ship looking for fish, which can be spotted on overturning ice floes during ice breaking.

Week 5: From Longyearbyen around Svalbard

[27. June 2017] 

The end of PS106/1 was garnished with amazing views of the Spitsbergen coastline in the midnight sun (Fig. 1). While scientists and crew members celebrated the successful completion of the PASCAL study and its interdisciplinary physical, biological and biogeochemical partners, wales and seals occasionally approached Polarstern.

Week 2 at the ice floe

[22. June 2017] 

The TROPOS aerosol container, with online and off-line instrumentation (high volume and size-resolved samplers), was installed on Polarstern on the upper deck to measure in-situ atmospheric aerosol physical-chemical properties.

Week 1 at the ice floe

[14. June 2017] 

After successfully building up all measurement sites we now have reached a full week with a multitude of observations. This report provides a few examples of what and how we are measuring in our little white floe, we call our home. Oddly enough we didn't manage to give it a name, probably because we all know that it will soon be gone.

In and on the ice

[08. June 2017] 

Following our planned schedule three persons where exchanged by helicopter as we passed Longyearbyen. .
