The third ITP was deployed in the Beaufort Sea on as part of the Beaufort Gyre Observing System (BGOS) during the JWACS 2005 cruise on the CCGS Louis S. St. Laurent. ITP3 and an US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy were deployed on a 3.5 m thick multiyear ice floe in a location designed to drift through the BGFE array during the following year. The ITP unit operated on a fast sample schedule of 4 one-way profiles between 10 and 760 m depth each day until the unit was damaged during an attempted recovery operation the following summer.
