ArcTrain Floating University on RV POLARSTERN cruise PS93.1
June 29 – July 17, 2015 from Svalbard to Tromsø
The ArcTrain Floating University offered us the opportunity to participate in a research cruise in the Arctic. It was embed in the RV Polarstern cruise PS93.1 which started at June 29th in Longyearbyen with approximately 2000 inhabitants the largest settlement on Spitsbergen and ended at July 17th in Tromsø, northern Norway. Onboard we were able to take part in all research activities that were carried out. The scientific program included oceanographic and atmospheric measurements as well as biological and geological sampling. Thus, this course was especially addressed to students that have not been on a research vessel before. In addition to the practical work in the diverse laboratories, different seminars and talks took place, basically about data processing and plotting as well as about the various scientific aims and recent studies of the participants like ocean currents in the Fram Strait, algae growth at the sea-ice edge, sedimentological processes in fjords and ocean basins etc.
Although I already attended three cruises before, I gained my knowledge about various geological sampling methods. I worked mainly in the wet lab sub-sampling the boxcorer and the large Kastenlot, cutting the gravity cores or slicing the smaller cores that were retrieved with the multicorer. Additionally I helped to deploy the multi-net. This device enabled us to sample plankton from different water depths. These samples were directly inspected under the microscope after retrieving them. Some of the sediment samples were washed through a sieve to examine them also under the binocular. Everybody had to participate in the parasound surveys that have been carried out 24 hours a day; shifts were two hours during the day or four hours during the night. They were performed to investigate the sediment structure and to find suitable coring locations.
Above all, the program was interesting for me because my PhD project is focusing on the paleoceanography of the Fram Strait based on samples from northern Spitsbergen. It was a really great experience to visit the impressive landscapes of this island. Furthermore, it was very inspiring to discuss with the numerous experts for this region onboard who have been working in this locality since many years. They contributed a lot to my comprehension of the mechanisms and conditions in this area. Retrospectively, it was an unforgettable experience to travel to the Arctic, especially with an icebreaker.
I would like to thank ArcTrain and the AWI Bremerhaven who gave me the opportunity to participate in this cruise.
