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.

Drake Passage Traverse

[08. March 2016] 

After wrapping up our work along the Chilean continental margin on the 28th of February we embarked on our first Drake Passage traverse toward the West Antarctic Peninsula. Our route was located just west of the narrowest point between South America and Antarctica in the south Pacific. We covered approximately 500 nautical miles over a widely unstudied section of the open ocean (Fig. 1). The main focus on our first Drake Passage traverse was to take water samples, sediment coring and oceanographic profiles.

Tierra del Fuego

[29. February 2016] 

The search for a geological station in the night from 21st to 22nd February, led us from the SW corner of Banco Namuncurá (also known as Burdwood Bank) into the deep sea in the northernmost part of the Drake Passage, along the NW continental margin and up again offshore the “Isla de los Estados”.

Stormy Departures

[22. February 2016] 

At midnight between the 19-20th of February we finally had the get-go for the FS Polarstern PS97 Expedition. It was a long way to this very point. An advance group had arrived in Punta Arenas six days prior to aid in changing over containers from the previous Antarctic Expedition PS96 with our materials. Unfortunately the FS Polarstern could not access the Mardones container loading pier in Punta Arenas, as it was still being occupied by a delayed freight ship. We had to wait until access was given for the extensive freight loading operations.

Farewell to East Antarctica and passage through the Weddell Sea

[10. February 2016] 

No – we did not forget about the four men at Drescher Inlet and left them there for overwintering. The helicopters brought them and all their equipment back to the ship last week. It was fascinating to see how they reported about their work with the typical Antarctic glaze in their clear eyes. The stories of their impressions bubbled out of their mouths like freshwater from a thawed water fall.
