ITP100 was deployed in open water in the Beaufort Sea on September 17, 2017 at 79° 59.1 N, 149° 43.5 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2017 cruise on the CCGS Louis S. St. Laurent. The ITP includes a dissolved oxygen sensor and is operating on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
