PS119 - Weekly Report No. 6 | 13 - 19 May 2019

To the smoking volcano of Saunders Island

[20. May 2019] 

Like last week, we spent the sixth week in the southernmost area of the South Sandwich Plate, from the back-arc spreading ridge of the segments 8 and 9 in the west to the Kemp Caldera. The volcano of Kemp Caldera is part of the collision zone with the South American plate to the East. A look to our expedition logo shows symbolically the spreading ridge on the left and flowing to the right the volcanoes, fore-arc area and subduction zone.

PS119 - Weekly Report No. 4 | 29 April - 5 May 2019

Active volcanoes of the South Sandwich Island Arc

[06. May 2019] 

We started the new week on Monday, 29th April, with a long dive to sample smoking chimneys and vent animals in the known hydrothermal field of the segment E2-South. Here we concentrated our efforts on the active vent systems around Dog’s Head, a complex structure consisting of 4 chimneys, which are lined up nicely one after the other, fused on their bases and characterised by single black smoking orifices in 12-15m height.

The East Scotia Ridge – where new seafloor grows

[29. April 2019] 

Despite not neglecting station work and the associated scientific analyses over the Easter days, we were able to celebrate the Easter. At first priority stands a big thanks to the crew of RV Polarstern as they decorated the public areas and canteens to create an Easterly feeling on board.


PS119 Weekly Report No. 2 | 16 - 22 April 2019

South Georgia - Gate to Antarctica

[24. April 2019] 

After the departure from Punta Arenas and an 8-hourly passage through the Magellan Strait RV Polarstern started a 4-day transit bound for South Georgia. This time without station work was used by our 51 scientists from Germany, USA, Costa Rica, Austria, UK, Bosnia & Herzegovina, Chile, Taiwan, France, India, Slovenia, Spain and Switzerland to further set up laboratories and to intensely exchange talks on the various research aims of this expedition.
