Weekly Reports Polarstern

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.

PS96 Weekly Report No. 2 | 14 till 20 December 2015

Sea water below, wind above and ice in between: “Polarstern” is thriving in the Southern Ocean waters between Bouvet Island and the Neumayer III station.

[21. December 2015] 

Just in time when the first weekly letter started its long distance, homeward bound journey - a “space odyssey” via satellite - the first tiny ice fragments appeared in the sea. One day later, and ice floes, knocked against the ship’s hull and woke up some of the “Antarctic greenhorns” sleeping in their berths (at the end of our cruise everyone on board will be missing this sound!).

At the beginning of an expedition

[14. December 2015] 

Northern Europeans are not used to seeing ubiquitous advent decoration at +25°C in the shade. Off we go – leaving the Table Mountain and heading south. Frozen water fits our idea of Christmas much better than a boiling hot sun.

PS96 | Cape Town to Punta Arenas

PS96 - Capa Town to Punta Arenas

[03. December 2015] 

ehe cruise leg PS96 FROSN, Filchner Ronne Outflow System Now (ANT XXXI/2) will start on December 6, 2015 in Cape Town and will end on February 14, 2016 in Punta Arenas.

In total, 45 scientists work on board in 8 different groups in various physical and biological disciplines and will address questions in meteorology, oceanography and bathymetry as well as benthic, ecological and fish biological problems. In addition, the ship has to provide time consuming logistical support of different kind during the expedition.


PS95.2 Weekly Report No. 3 | 23. till 29. November 2015

In the Benguela Upwelling Region

[01. December 2015] 

On the way to Cape Town we continued with our regular underway measurements, only interrupted by two full stations with CTD and plankton nets on Monday (ca. 10°S) and Thursday (20°15’S). The last CTD on Thursday was celebrated and we were a bit sad that this was the last station.

PS95.2 Wochenbericht No. 2 | 16 till 22 November 2015

Across the Equator

[24. November 2015] 

After leaving the Cape Verde Islands, the next days were rather quiet. We had regular stations every morning with XBT mesurements and bucket samples from the slow-moving ship. As time for stations is very short on transect cruises we have to use underway measurements as much as possible. Additional measurements are obtained using instrumentse comprising of the ship’s thermosalinograph, the Ferry Box and satellite images.
