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.

Polarstern, 07°0´N, 23°48´W

[18. June 2019] 

On Friday the 14.06 we arrived at the equator. We stayed put there for a while to measure the different  over depth.  If one stood on the portside of the ship one was in the southern Hemisphere and standing on the starboard side, one was in the northern Hemisphere. The meteorologists could wander between both, outside their office.

Polarstern in Port Stanley

[12. June 2019] 

The PS120 Transit on RV „Polarstern“between Port Stanley and Bremerhaven is a research- and training expedition. Twenty-three young scholars, who were chosen from 800 applicants, are taking part in the SoNoAT 2019 „Changing Oceans Changing Future“ programme. This is set upon RV „Polarstern“ as a collaboration of POGO (Partnership for Observations in the Global Oceans),  NIPPON FOUNDATION and AtlantOS.

The last week at sea

[03. June 2019] 

After our storm on last Friday, the sea only calmed down very slowly and station work was only possible with two CTD stations in the late night towards Saturday. The deployments were made about 60 km to the West of the spreading centre on its flank. There, the seafloor is parted by North-South orientated, parallel faults covered by young sediment, and we discovered both in the sediments as well as in the water column indications for fluid circulation in the Parasound recordings.

The expedition‘s stormy

[27. May 2019] 

The rapid changes in weather condition, which hit us last weekend, was exemplaric for the entire week. While were able to achieve the 450th dive of MARUM ROV QUEST (Fig. 2) on the ridge segment E2 of the East Scotia Ridge on Saturday, the storm on Sunday, which we endured in the ailee of Zavodovski Island, showed us that Antarctic winter has started.

To the smoking volcano of Saunders Island

[20. May 2019] 

Like last week, we spent the sixth week in the southernmost area of the South Sandwich Plate, from the back-arc spreading ridge of the segments 8 and 9 in the west to the Kemp Caldera. The volcano of Kemp Caldera is part of the collision zone with the South American plate to the East. A look to our expedition logo shows symbolically the spreading ridge on the left and flowing to the right the volcanoes, fore-arc area and subduction zone.
