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.

Chemistry on Board

[23. July 2018] 

Now we have been working in the working area for 7 days which were intense but successful. A lot of moorings were recovered and deployed. We also took many water and sediment samples and videos which are part of the work of the FRAM infrastructure.

Into the Arctic

[16. July 2018] 

A walk through the ship shows: Everything is ready to go! Just a few days ago there were partly unpacked transport boxes everywhere (from whole containers to small cardboard boxes).

The Final Strai(gh)t

[11. June 2018] 

On 5th June after leaving Las Palmas on Gran Canaria we again reduced our speed for 5 hours so that we could tow the Triaxus/topAWI for one final test.  Thereupon followed a final comparison station with CTD and the optical measurements package. Thereafter, we were supposed to head to Bremerhaven with all haste and without further ado.

The Tropical North Atlantic: Cold in the Water, Dust in the Sky

[04. June 2018] 

The whole week long we sailed in the North-east Trade Wind zone under skies with only a few clouds, but with strong head-winds for Polarstern. By crossing the northern tropic, the Tropic of Cancer, at 23° 26’ 05” North during the night of  31st May to 1st June we have left the Tropics and are again in the Subtropics. Although we have been moving through the Tropics and Subtropics, the water and air surrounding us with temperatures of around 20°C have been relatively cool, 10° colder than the daytime temperatures in much of Germany.  That...

Cruising through the Blue

[28. May 2018] 

After entering the Tropics in the Southeast Trade Wind region and sailing under cloudless skies, the second half of the week was largely cloudy with frequent rainfall. We had arrived in the Inter-Tropical Convergence Zone, in which the air masses transported by the Southeast Trade Winds and their northern hemispheric counterpart, the Northeast Trade Winds, rise up and produce thick clouds reaching high into the atmosphere.
