ITP 27 was deployed on a 2.0 m thick ice floe in the Transpolar Drift from the Russian Research Vessel Academic Federov. The ITP operated on a typical sampling schedule of 2 one-way profiles between 7 and 760 m depth each day. In April 2010, over a year after the last transmission of the buoy, the surface package (with severed mooring cable) was discovered at 66° 3.5' N and 21° 41.5' W near the remote village of Holmavik in Iceland, and with the assistance of Marine Research Institute of Iceland was transported to Rekjavik and subsequently shipped back to Woods Hole.
