ITP53 was deployed on August 4, 2011 on a 3.80 m thick ice floe in the Beaufort Sea at 77° 34.2 N, 145° 56.4 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2011 cruise on the CCGS Louis S. St. Laurent. The ITP is operating on a typical sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
