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.

At the 79°N Glacier

[26. September 2017] 

We are looking back on a very active and exciting week. In the beginning our work was still concentrated on the area of the shelf break of Northeast Greenland at the mouth of Westwind Trough, with the latter representing a depression leading toward the inner shelf. In the trough relatively warm Atlantic Water can be found near the sea floor.

The forerunners of Greenland

[19. September 2017] 

In the evening of 12 September the research icebreaker R/V Polarstern left the port of Tromsø (Norway). On board there are scientists from seven nations who cover the range from physical oceanography, geochemistry, glaciology, geodesy, geology, geophysics, atmospheric physics and chemistry as well as marine biology and  biogeochemistry. The aim of the “Greenland ice sheet/ocean interaction” (GRISO) expedition is to unravel the complex physical interactions between the ocean and the ice sheet of Northeast Greenland, as well as their implications for...

Expedition „ROBEX-DM“

[31. August 2017] 

On Tuesday August 22 at 19:00 POLARSTERN left Tromsö with an unusual freight on board into direction of Svalbard. Unusual, because 10 of the 40 scientists on board are space experts and special are also the new and innovative robotic systems, which should improve our capabilities in deep-sea research. The new technologies include 3 different types of benthic crawler, each designed for its specific scientific purpose on the bottom of the sea, a glider for water column studies, unmanned aerial vehicles (UAVs) to support AUV operations under sea ice and an...

Long-term investigations & catching micro plastics

[14. August 2017] 

We finished our scientific program in the western Fram-Strait at the East-Greenland slope and went back to our main research area of the long-term observatory LTER-HAUSGARTEN – west off Svalbard. Like every summer here we realize an extensive sampling program from the sea-surface through the water column down to the seafloor. Here we are analyzing at almost twenty stations within water depth between 200 m and 5500 m seawater, plankton is caught, deep-sea sediments are sampled and photos and videos from the seafloor were made. By a...
