ITP44 was deployed on October 9, 2010 on a 1.5 m thick ice floe in the Beaufort Sea at 75° 51.6 N, 134° 39.7 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2010 cruise on the CCGS Louis S. St. Laurent. The ITP includes a prototype MAVS current sensor and is operating on a pattern profiling schedule including 2 one-way profiles between 7 and 760 m depth each day.
