Research Icebreaker Polarstern
« on: June 09, 2017, 09:31:09 PM »
As suggested on another thread I'm starting this to have a dedicated place for information on the activities of this German research vessel which visits both arctic and antarctic waters.

There is the Polarstern blog: some entries are only available in german it seems.

worth looking at photos nevertheless

A bit more English language info is available at:

https://www.awi.de/en/expedition/ships/polarstern.html

together with the AWI's own Polarstern position map. The University of Bremen provide yet another map:

Wikipedia article on RV Polarstern includes:
... It is planned that she will be replaced by Polarstern II around the year 2017, after it was decided that the European Research Icebreaker Aurora Borealis will not be built in her original form.
and
History
On 7 September 1991, Polarstern, assisted by the Swedish arctic icebreaker Oden reached the North Pole as the first conventional powered vessels.[3] Both scientific parties and crew took oceanographic and geological samples and had a common tug of war and a football game on an ice floe. Polarstern again reached the pole exactly 10 years later[4] together with the USCGC Healy. She returned for a third time on 22 August 22 2011 at exactly 9.42 a.m. This time she reported the most frequently recurring ice thickness at 0.9 m compared with 2 m in 2001, which corresponds to the long-term average.[5]

On March 2, 2008, one of the vessel's helicopters crashed on a routine flight to the Antarctic Neumayer II base. The German pilot and a Dutch researcher were killed, three other passengers were injured.[6][7]

On October 17, 2008, Polarstern was the first research ship to ever travel through both the Northeast Passage and the Northwest Passage in one cruise, thus circumnavigating the North Pole.[8]

Good thread. I'm surprised it didn't exist yet.

A new post is up on (in german) on the polarstern blog.
https://blogs.helmholtz.de/polarstern/2017/06/wir-fegen-das-meereis-von-unten/
I'll try to give a summary in english
A ROV is operating under the ice, focussed on water depths of up to 20m to take samples of flora and fauna. A net is fixed to the ROV and a broom is used to brush algae and small animals from the underside of the ice.
To investigate how distribution of the various organisms varies over daily cycles and longer periods (i.e. as ice properties change) Polarstern will stay alongside the same floe for two weeks.
