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.

PS100 - Weekly Report No. 1 | 18 July - 24y July 2016

The 100th expedition

[28. July 2016] 

In the evening of 18 July the research ice breaker Polarstern left the port of Tromsö (Norway) in cloudy and windy conditions to start its 100th expedition. On board there are scientists from 13 nations.


PS99 - Weekly Report No. 5 | 11 July - 15 July 2016

“Groundwork”

[18. July 2016] 

As already announced in the last weekly report, today we will provide details about the work of the biogeochemists and biologists during “Polarstern” expedition PS99.2. Their goal is to investigate organisms and processes at the deep seafloor.


PS99 - Weekly Report No. 4| 4 July - 11 July 2016

Water World

[11. July 2016] 

As already announced in the last weekly report, today we will provide details about the work of the phyto-opticians, biogeochemists, planktologists and sedimentologist during RV Polarstern expedition PS99.2. Their goal is to investigate the organisms and processes in the water column.


PS99 - Weekly Report No. 3| 27 June - 3 July 2016

In the air, in the water column and at the deep seafloor

[04. July 2016] 

For about a week we have been operating in our investigation area, i.e. the LTER (Long-Term Ecological Research) Observatory HAUSGARTEN. In addition to our “traditional” gear to study the open and deep ocean, like water samplers, plankton nets, sediment corers and moorings, we will also deploy a number of comparably complex high-tech gear to complement our long-term studies. This includes an Un-manned Aerial Vehicles (UAV), a 3000 m depth-rated Autonomous Underwater Vehicle (AUV), free-falling lander systems (Bottom-Lander) and - for the first time in...


PS99 - Weekly Report No. 2| 20 June - 26 June 2016

A short stopover?

[27. June 2016] 

On 23rd June, we reached Longyearbyen and the expedition PS99.1 came to an end. The hydrographical, biological and geological studies of the two EUROFLEETS2 projects, explained in detail in our first weekly report, could successfully be completed. Within only 2½ days available ship-time we managed to sample the water column and the seafloor, to map the seafloor with a towed camera system, and to exchange moorings with current-meters and sediment traps at a total of 40 stations at water depths between 150 and 1800 m. Exhausted but as happy as could be...
