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.

Western South Scotia Ridge

[02. April 2019] 

During the past week, science has focused on bathymetry, oceanography and heat flow/geology transects along the western end of the South Scotia Ridge between the Antarctic Peninsula and the South Orkney Plateau. Our work was only briefly interrupted by a gale-force storm that passed through our area.

Powell Basin

[25. March 2019] 

Out of the heavy sea ice of the Weddell Sea, we have spent the past week in open water and loose sea ice in the Powell Basin. So far, we have conducted a short bathymetric survey, deployed a lander, completed an oceanographic transect and collected geological and biological samples.

Further to the North and two more stations

[18. March 2019] 

During the last week, we continued our northward travel to the Erebus and Terror Gulf completing two more stations. Another highlight were curtesy visits between the Polarstern and the Argentinian vessel Almirante Irizar.

Northward journey and the first station

[14. March 2019] 

During the last week, we travelled for more than 60 nautical miles to the north and only stopped our journey for the first sampling station where we deployed most of our scientific equipment. Since then, we are busy to analyse water, sediment and benthos samples or to preserve them for later onshore analyses.

Step by step

[11. March 2019] 

We are now almost within sight of A68 and a survey to measure the thickness of the sea ice has already crossed A68. Unfortunately, heavy ice conditions made our progress quite cumbersome. During the past week, we literally nudged our way metre by metre through the ice. At times, our progress was so small that it did not even compensate for the displacement of the ice-drift.
