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.

The expedition comes to an end

[06. September 2016] 

Today we have completed our research programme at the Knipovich Ridge south of Fram Strait. We are now on the transit toward Tromsø, where we will arrive in the morning of 6 September.

At the 79° Glacier

[29. August 2016] 

Yesterday we finished our investigations in the close vicinity of the 79°N glacier. Now R/V Polarstern is exploring the southern end of Westwind Trough on the inner shelf. We had already paid a visit to the outer part of this depression earlier in the expedition.

Working in Norske Trog

[23. August 2016] 

Meanwhile R/V Polarstern has worked her way toward the inner shelf of Northeast Greenland. We have reached the transition from Norske Trough to Westwind Trough, which is where the 79°N glacier meets the sea. In this region, sea ice often prevails the whole year round.

Back at the Greenland Ice Shelf

[16. August 2016] 

In sunny weather and light sea ice conditions we find ourselves once again on the shelf of Greenland  –this time in Norske Trough. In the beginning of the week we were able to accomplish most of the oceanographic, biological and biogeochemical workload planned along the zonal transect through central Fram Strait along 78°50’N. Subsequently we added to the mooring array deployed along the Greenwich Meridian in the second week of the expedition the southernmost mooring at 78°10’N.

Questions about climate change

[08. August 2016] 

After having reached the northernmost point of the expedition at the end of last week, we moved southeastward across the East Greenland Current toward the continental shelf of Northeast Greenland, that we reached at the outlet of Westwind Trough.
