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.

At Neumayer Station

[21. January 2019] 

Neumayer, finally!  Polarstern took berth about 20 km north of the German Antarctic Station (officially named Neumayer Station III) at the extreme edge of the ice shelf (Fig. 1) and commences to lift one container after the other from its cargo holds onto sledges on the ice shelf to be towed by snowcats to the station.

On the way to Neumayer Station III

[14. January 2019] 

Having refurbished all oceanographic moorings of the eastern Weddell Sea (Fig. 1), the ship can finally shifts its attention to the biological projects aboard.

Oceanography

[07. January 2019] 

After nearly a week at sea, the oceanographic station work falls into routine: CTD (conductivity – temperature – pressure probe) in the water – lowering to the bottom – hoisting – CTD aboard.  This is frequently followed by the deployment of an Argo float, freely drifting profiling probes which will regularly provide the oceanographic key parameters, temperature and salt, from within the upper 2000m of the ocean for the next 5 years.

A full loaded vessel

[21. December 2018] 

As planned, Polarstern pushes away from the pier in Cape Town on 15 December at 4pm, taking off for her 117th expedition to the Antarctic.

Satellite orbits and laser beams

[07. December 2018] 

On our way further south, we sailed on various courses and with different speeds.
