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.

PS93.2 Weekly Report No. 4 | 10 August until 15 August 2015

With High Tech into the Deep Sea

[14. August 2015] 

This is the fourth and final weekly report from a technically and logistically very challenging expedition to the LTER (Long-Term Ecological Research) observatory HAUSGARTEN.


PS93.2 Weekly Report No. 3 | 3 August until 9 August 2015

At ground level, in the water, and in the air – marine research in 2015

[10. August 2015] 

As promised in our last weekly report, we would like to start with a description of the benthic work, i.e. the work carried out at the deep seafloor. Yet, there is much more to marine biological research, as you will see/read below.


PS93.2 Weekly Report No. 2 | 27 July until 2 August 2015

„Water World“ – Investigations in the water column

[03. August 2015] 

The second weekly report from this year’s cruise to the deep-sea observatory HAUSGARTEN will present the work carried out by our planktologists and marine chemists.


PS93.2 Weekly Report No. 1 | 21 until 26 July 2015

Same procedure as every year: „Gardening“ in the deep Arctic Ocean

[28. July 2015] 

On June 21st, 46 scientists, engineers, technicians, and students coming from 10 nations embarked in sunny Tromsø to participate in the second leg of RV “Polarstern” expedition PS93.


PS93.2 Summary | 21 July till15 August 2015

The Polarstern Expedition PS93.2

21.07.2015 till 15.08.2015 - Tromsø - Tromsø

[21. July 2015] 

The scientific work during the expedition PS93.2 will support the time-series studies at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN, where we document Global Change induced environmental variations on a polar deep-water ecosystem. This work is carried out in close co-operation between the HGF-MPG Joint Research Group on Deep-Sea Ecology and Technology, and the PEBCAO Group (Phytoplankton Ecology and Biogeochemistry in the Changing Arctic Ocean) at AWI and the Helmholtz Young Investigators Group SEAPUMP (Seasonal and regional food...
