Weekly Reports Polarstern

The Expedition PS115/1 Tromsø - Longyearbyen

Cruise PS115.1 of RV Polarstern headed by BGR leads to the northern North Atlantic off Greenland. Scientific goal of the research activities is to acquire new geophysical data on the geological structures below the seafloor in this particular region. This information is of special importance to reconstruct the plate tectonic history of the Arctic over the last 60 Million years, which is one of the scientific goals of project GREENMATE. Besides geophysical surveying it is also planned to extract seafloor sediment samples.  The subsequent investigations include geochemical analysis to understand the natural carbon circulation and to deduce the palaeoclimate evolution in the Arctic. The research activities also include helicopter operations to sample rock material from near coastal outcrops. The international team of 48 scientist from countries include among others researcher teams from the Alfred-Wegener-Institute Helmholtz Centre for Polar and Marine Sciences, Bremerhaven, the GEOMAR Helmholtz Centre for Ocean Research, Kiel, the Helmholtz Centre for Environmental Research, Leipzig, and the University of Bremen.

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.

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.

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.

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...
