ITP64 was deployed in open water in the Beaufort Sea on August 28, 2012 at 78 46.5 N, 136 39.8 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2012 cruise on the CCGS Louis S. St. Laurent. The ITP includes a dissolved oxygen sensor and full biosuite system and a fixed SAMI PCO2 with SBE-37 microcat at 6 m depth and is operating on a pattern profiling sampling schedule including one full one-way profile between 7 and 760 m depth every 1.5 days. More information on the biosuite sensor package and data handling can be found here .
