ITP25 was deployed on September 22, 2008 on a 1.6 m icefloe in the Beaufort Gyre at 80° 38.5 N, 166° 46.0 W from the German Research Vessel Polarstern as part of the European Union DAMOCLES Program. On the same icefloe, an Optimare ITAC with GPS mast and University of Hamburg (ZMAW) PAWS meteorological station were also installed. The ITP is operating on a typical sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
