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.

On the way

[25. February 2019] 

Right now, we are southeast off James Ross Island in the western Weddell Sea breaking our way to the iceberg A68 and the Larsen C ice shelf. The distance to the northern tip of A68 measures ca. 75 nautical miles (nm), slightly over 135 km. To our working area, the area where A 68 broke of the Larsen C ice shelf, the distance is ca. 180 nm (330 km)…

A bumpy start

[18. February 2019] 

We are still in Punta Arenas at the pier in Cabo Negro to take on fuel. Later, we need to take on kerosene for the helicopters and finish last cargo operations. If everything works according to plan, we should hopefully be on our way to Antarctica on Monday morning. However, all in good order …

Good-bye Antarctica

[06. February 2019] 

The scientific party and crew are facing their final big challenge: a four day long dense sequence of CTDs, Ultra Clean CTDs (Fig. 1) as well as mooring recoveries and deployments.

Business as usual.

[31. January 2019] 

Business as usual. Polarstern plows her way through the open waters of the Weddell Sea – the ice cover is at it minimum, subjectively at least – and heads for one mooring position after the other.

At Neumayer Station

[21. January 2019] 

Neumayer, finally!  Polarstern took berth about 20 km north of the German Antarctic Station (officially named Neumayer Station III) at the extreme edge of the ice shelf (Fig. 1) and commences to lift one container after the other from its cargo holds onto sledges on the ice shelf to be towed by snowcats to the station.
