The Expedition PS120 Port Stanley - Bremerhaven

The transit cruise from Port Stanley to Bremerhaven will begin on 02.06.2018 and ends on the 29.06.2019.

The cruise is primarily dedicated to the training of students and the preparation and testing of onboard equipment for the upcoming MOSAIC project. During a “floating summer school” an international group of 25 students from 23 countries will be trained in basic techniques of oceanography and remote sensing on a North-South transect from Port Stanley to Bremerhaven (South North Atlantic Training; SoNoAT). The participants will learn how to take samples, how to process them and deal with the accompanying data. The main water masses between the Atlantic and the North Sea will be characterized in terms of their hydrographic features down to a depth of approx. 500 m and more.

In preparation for the following MOSAIC expeditions sensors will be re-calibrated and configured to fit in the board systems. This should assure the functionality during the MOASIC programme, the scholar will be involved in the sensor testing. Additional to the sensors the medical equipment will be inventoried and updated during this cruise.

A further focus during the transit cruise will be physical and chemical measurements as well as detection of mircoplastics and EDNA. In addition, the students will get an introduction into the physics of the climate system, international climate negotiations and data analyses.

A three-day workshop will be held land based to prepare the scholars in application and usage of programming tools and methods.

The floating summer school is a joint project between the Alfred Wegener Institute Helmholtz-Centre for Polar- and Marine Research, the POGO Centre of Excellence, ATLANTOS and the OCEAN TRAINING PORTAL (OTP). It is funded by the Nippon Foundation / POGO Centre of Excellence and the OTP and supported by REKLIM and PORTWIMS (Portugal Twinning for innovation and excellence in marine science and Earth observation).

Polarstern is scheduled to arrive in Bremerhaven on 29.06.2019 and thus ends the expedition PS120.

Variety of station work – science at its finest

[25. January 2016] 

A huge, wooden box is sitting on the deck for several days. When it reveals its content, a weather station appears, which is destined to be deployed on a solid ice floe and to keep in touch with home via satellite connection. Like everything what we deploy on ice floes we won’t see it again. However, how will it be deployed onto the ice?

Approach through the A23A polynya to Ronne Depot

[21. January 2016] 

A23A: The Filchner Ice Shelf once had a pointed edge. This is sometimes referred to as the “Horn von Druzhnaya“ - named after a former Russian summer camp which was sited there. The horn broke off back in 1986 and disintegrated into three large fragments that drifted offshore. The two smaller fragments (A22+A24) embarked on a journey around Antarctica and ‘merged’ with the Southern Ocean. The largest fragment A23A ran aground on Berkner Bank. This iceberg is still resting there today, after having been labelled ‘A23A’ for identification purposes.

The New Year‘s Day profile and the truth uncovered by the corer

[13. January 2016] 

The New Year started immediately with comprehensive station work. Occasionally, however, you could get the impression that Neptune was unhappy with this work being carried out in his private home.

Visit at Neumayer station and research on public holidays

[05. January 2016] 

After three days of ice breaking near Neumayer station “Polarstern” finally arrives at the ice shelf front. Once again the ship’s nautical officers did an excellent job! The unloading of tons of cargo and supply of the station progress very smoothly and while all this hard work is going on, some scientists and crew members are given the opportunity to have a look at the impressive Neumayer III station.

Sea water below, wind above and ice in between: “Polarstern” is thriving in the Southern Ocean waters between Bouvet Island and the Neumayer III station.

[21. December 2015] 

Just in time when the first weekly letter started its long distance, homeward bound journey - a “space odyssey” via satellite - the first tiny ice fragments appeared in the sea. One day later, and ice floes, knocked against the ship’s hull and woke up some of the “Antarctic greenhorns” sleeping in their berths (at the end of our cruise everyone on board will be missing this sound!).
