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.

End of a successful Expedition

[13. March 2017] 

A world of gigantic icebergs made the scenery which Polarstern passed through on its track from Pine Island Bay to the western Amundsen Sea Embayment. The icebergs are so abundant here because of a bathymetric ridge that extends northwards from Bear Peninsula and onto which the icebergs are grounded and move only slightly at the peaks of high tide.

Interesting Discoveries

[06. March 2017] 

A week passed by that was full of alternating expectations and events. Sea ice got in the way, but such is life when working in polar environments. But there is always a Plan B, and this time we continued in the eastern part of the Amundsen Sea Embayment, where sea ice and weather conditions were more favourable.

The MeBo drilling program and stations on land

[27. February 2017] 

An exciting week has passed with changing plans as becoming part of the daily routine. Why is it impossible to follow a many days’ long work program in this region? Our work is mainly focussed on the drilling program with the MeBo.

The second week

[21. February 2017] 

A broad belt of thick pack ice normally blocks the northern entrance to the shelf of the Amundsen Sea Embayment. But we encountered an unusually small sea-ice cover as also observed by satellite data from around entire Antarctica this southern summer. With only an average 3/10 to 5/10 ice cover, Polarstern easily managed to pass this belt so that we soon arrived at our first station west of Thurston Island to sample marine sediments.

Final preparations

[21. February 2017] 

Punta Arenas being the southernmost town of Chile, situated at the Strait of Magellan between Patagonia and Tierra del Fuego, is the starting point of our expedition to the Amundsen Sea of Antarctica.
