Weekly Reports Polarstern

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.

PS111 -Weekly Report No. 6 | 24 February - 2 March 2018

From the Northern Transect to Halley Bay

[05. March 2018] 

A third transect from this week now also covers the Northern part of the Filchner Depression. Net and water samples as well as short sediment cores kept all research groups on Polarstern busy 24 hours a day.

Ice and water in the Filchner Depression

[26. February 2018] 

Favourable ice conditions and stable weather with southwesterly winds enabled Polarstern to go far south into the Filchner Depression and to cross directly in front of the Filchner Ice Shelf close to 44° W this week.

From the Ronne Ice Shelf Polynya

[19. February 2018] 

During this week we completed a transect along the Ronne Ice Shelf front, extending from 50°W to 60°W. Every instrument on board has been used.

[13. February 2018] 

This week’s work on PS111 was focused on moorings. Instruments, which have stayed in the water for up to 4 years, were retrieved and re-deployed.

Neumayer and beyond

[09. February 2018] 

Now we have arrived – Polarstern makes her way easily through the disintegrating winter sea ice cover, heading for the northeastern edge of Ekström Ice Shelf.
