ITP9 was deployed on a 2.7 m thick icefloe on 11 September 2007 at 87° 4.217 N, 130° 16.528 W from the Russian icebreaker "Akademik Federov" as part of the European Union DAMOCLES Program. On the same icefloe, a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (IMB 30295) was also installed. The ITP is operating on a typical sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
