tug of war and a football game on an ice floe. Polarstern again reached the pole exactly 10 years later[together with the
USCGC Healy . It returned for a third time on August 22, 2011 at exactly 9.42 a.m. This time it reported the most frequently recurring ice thickness at 0.9m compared with 2m in 2001, which corresponds to the long-term average.
On October 17, 2008,
Polarstern , as the first research ship ever traveled through both the
Northeast Passage and the
Northwest Passage in one cruise and thus circumnavigated the North Pole.
