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.

White smoker and yellow sulphur of the Kemp Caldera

[14. May 2019] 

On Sunday, 5th May, we arrived at the Kemp Caldera, a prominent crater of volcanic origin at the southern end of the South Sandwich volcanic arc.

Active volcanoes of the South Sandwich Island Arc

[06. May 2019] 

We started the new week on Monday, 29th April, with a long dive to sample smoking chimneys and vent animals in the known hydrothermal field of the segment E2-South. Here we concentrated our efforts on the active vent systems around Dog’s Head, a complex structure consisting of 4 chimneys, which are lined up nicely one after the other, fused on their bases and characterised by single black smoking orifices in 12-15m height.

The East Scotia Ridge – where new seafloor grows

[29. April 2019] 

Despite not neglecting station work and the associated scientific analyses over the Easter days, we were able to celebrate the Easter. At first priority stands a big thanks to the crew of RV Polarstern as they decorated the public areas and canteens to create an Easterly feeling on board.

South Georgia - Gate to Antarctica

[24. April 2019] 

After the departure from Punta Arenas and an 8-hourly passage through the Magellan Strait RV Polarstern started a 4-day transit bound for South Georgia. This time without station work was used by our 51 scientists from Germany, USA, Costa Rica, Austria, UK, Bosnia & Herzegovina, Chile, Taiwan, France, India, Slovenia, Spain and Switzerland to further set up laboratories and to intensely exchange talks on the various research aims of this expedition.

Departure to our research area in the Scotia Sea

[16. April 2019] 

On Monday, 15th of April 2019, at 13:48 local time RV POLARSTERN left her mooring at position C in front of the harbour of Punta Arenas for a 3-day transit toward her first research area in the waters of the sub-Antarctic island of South Georgia.
