End of a successful Expedition

[13. March 2017] 

A world of gigantic icebergs made the scenery which Polarstern passed through on its track from Pine Island Bay to the western Amundsen Sea Embayment. The icebergs are so abundant here because of a bathymetric ridge that extends northwards from Bear Peninsula and onto which the icebergs are grounded and move only slightly at the peaks of high tide.

Interesting Discoveries

[06. March 2017] 

A week passed by that was full of alternating expectations and events. Sea ice got in the way, but such is life when working in polar environments. But there is always a Plan B, and this time we continued in the eastern part of the Amundsen Sea Embayment, where sea ice and weather conditions were more favourable.

The MeBo drilling program and stations on land

[27. February 2017] 

An exciting week has passed with changing plans as becoming part of the daily routine. Why is it impossible to follow a many days’ long work program in this region? Our work is mainly focussed on the drilling program with the MeBo.

The second week

[21. February 2017] 

A broad belt of thick pack ice normally blocks the northern entrance to the shelf of the Amundsen Sea Embayment. But we encountered an unusually small sea-ice cover as also observed by satellite data from around entire Antarctica this southern summer. With only an average 3/10 to 5/10 ice cover, Polarstern easily managed to pass this belt so that we soon arrived at our first station west of Thurston Island to sample marine sediments.

Punta Arenas being the southernmost town of Chile, situated at the Strait of Magellan between Patagonia and Tierra del Fuego, is the starting point of our expedition to the Amundsen Sea of Antarctica.
