ITP 44 was deployed on a 1.5 m thick ice floe in the Beaufort Sea as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2010 cruise on the CCGS Louis S. St. Laurent. The ITP included a prototype MAVS current sensor and was scheduled to operate on a pattern profiling schedule including 2 one-way profiles between 7 and 760 m depth each day.  However, communications between the underwater and surface unit failed after the first partial down profile, presumably due to a hardware problem with the inductive modem circuit.
