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.

Discovering the ice-covered Arctic deep-sea: Of robots, minerals and microbes

[19. October 2016] 

The fifth week of expedition PS101 has made significant progress in the study of hot vents and seamounts under the ice-covered seas. The under ice robot NUI samples the seafloor.

New tools and concepts to observe the changing Arctic Ocean

[11. October 2016] 

Expedition PS101 tests, deploys and recovers several new types of instrumentation for the observation of ice, ocean and seafloor processes in the Central Arctic. A main aim is to observe and analyse the changes in the sea ice cover, and its causes and consequences for ocean and life.

Hot and Cold at Gakkel Ridge of the Central Arctic Basin

[04. October 2016] 

The third week of expedition PS101 was dedicated to the study of hydrothermal venting under the ice. The Arctic fall season has begun.

Under Ice Life at Karasik Seamount

[26. September 2016] 

The second week of Expedition PS101 was dedicated to the discovery of the deep-sea ecosystem at Karasik Seamount. This giant seamount rises over 4000m above the Arctic basin and is teaming with life.
