PS 117 – Weekly Report No. 5 | 21 - 27 January 2019.

Business as usual.

[31. January 2019] 

Business as usual. Polarstern plows her way through the open waters of the Weddell Sea – the ice cover is at it minimum, subjectively at least – and heads for one mooring position after the other.

At Neumayer Station

[21. January 2019] 

Neumayer, finally!  Polarstern took berth about 20 km north of the German Antarctic Station (officially named Neumayer Station III) at the extreme edge of the ice shelf (Fig. 1) and commences to lift one container after the other from its cargo holds onto sledges on the ice shelf to be towed by snowcats to the station.

On the way to Neumayer Station III

[14. January 2019] 

Having refurbished all oceanographic moorings of the eastern Weddell Sea (Fig. 1), the ship can finally shifts its attention to the biological projects aboard. 

PS117 - Weekly Report No. 2 | 21 December 2018 - 5 January 2019


[07. January 2019] 

After nearly a week at sea, the oceanographic station work falls into routine: CTD (conductivity – temperature – pressure probe) in the water – lowering to the bottom – hoisting – CTD aboard.  This is frequently followed by the deployment of an Argo float, freely drifting profiling probes which will regularly provide the oceanographic key parameters, temperature and salt, from within the upper 2000m of the ocean for the next 5 years.
