Week 8: Returning to Svalbard

[17. July 2017] 

After concluding our 4th ice station at the northernmost location of this expedition, Polarstern set a south-westerly course, heading for the position of our well-known PASCAL ice floe of PS 106/1. This time, many open leads allowed a mostly gentle passage through the ice.

Week 7: In the deep Arctic Ocean

[10. July 2017] 

During our northward transect, Polarstern bit its way through heavy sea ice, hard as concrete and covered with a thick layer of snow. This altogether slowed down our progress into the north significantly. During our journey in the thick ice across the deepening Arctic Ocean, wildlife became scarcer and scarcer. Patches of Melosira arctica were only spotted rarely.

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.
