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.

Under Saharan Dust

[16. November 2015] 

After 13 days at sea Polarstern reached Las Palmas on the Canary Islands on the 10th November. The team of three geophysicists left the ship and six new people came on board: two technicians to test the satellite antennae system, Sören Krägefski to calibrate the EK60 Ecosounder, two people to support the TROPOS team (Leipzig Institute for Tropospheric Research) and Karin Lochte as the new cruise leader. We also had a visit of the Director and colleagues from the Spanish Institute of Oceanography IEO (Instituto Espanol de Oceanografia) and POGO, who were...

An unexpected encounter and the issue with the motion sensor

[09. November 2015] 

“Heaven smiles when angles travel” – tells an old German saying. If this is true, we must have many angles on board looking at the extremely good weather conditions we have had till now. It didn’t even breeze in the Biscay and thus, we were able to conduct all planned station work.

The “floating summer school” begins

[03. November 2015] 

On Tuesday October 29, 2015 was cast off at 13:00 h on the dot. Two tugboats maneuvered Polarstern into the lock. Once in the Weser she starts steaming and leaves Bremerhaven southbound for the Antarctic season 2015/16. 43 crew members as well as 52 scientists and students are on board.

The Polarstern-Expedition PS95

Floating summer school

[29. October 2015] 

The expedition PS 95 is split in two legs: PS95.1 transit cruise from Bremerhaven to Las Palmas and PS 95.2 from Las Palmas to Cape Town. Both legs are dedicated to the training of students.


PS94 Weekly Report No. 7 | 28. September till 4. October 2015

Ice-free diet for copepods

[06. October 2015] 

How will the Arctic ecosystems react on climate change – how will they change as a consequence of the ongoing summer sea ice decrease? These are the questions moving our biologists and therefore they study flora and fauna in the sea ice, the water and at the sea floor. Hence our transects through the Arctic contain also net hauls and a considerable part of the water from the rosettes goes to the biologists.
