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.

Transit cruise from Punta Arenas to Las Palmas

[06. April 2017] 

This year’s return journey of RV Polarstern from Antarctica began with the departure in Punta Arenas in the evening of March 20, 2017. We left a bit earlier than scheduled with a small team of scientists and technicians on board through the Magellan Strait bound for the Atlantic.

[21. March 2017] 

In this last weekly report, I will give a short résumé of our exciting expedition. We left with great expectations for the Amundsen Sea 6 weeks ago with the MeBo drilling device and other scientific equipment on board to collect samples and data that will help us to decipher the history of the West Antarctic Ice Sheet.

End of a successful Expedition

[13. March 2017] 

A world of gigantic icebergs made the scenery which Polarstern passed through on its track from Pine Island Bay to the western Amundsen Sea Embayment. The icebergs are so abundant here because of a bathymetric ridge that extends northwards from Bear Peninsula and onto which the icebergs are grounded and move only slightly at the peaks of high tide.

Interesting Discoveries

[06. March 2017] 

A week passed by that was full of alternating expectations and events. Sea ice got in the way, but such is life when working in polar environments. But there is always a Plan B, and this time we continued in the eastern part of the Amundsen Sea Embayment, where sea ice and weather conditions were more favourable.
