ITP118 was deployed on a 1.0 m ice floe in the Beaufort Sea on September 20, 2019 at 80° 2.5 N, 140° 10.2 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2019 cruise on the CCGS Louis S. St. Laurent. The ITP is operating on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day and includes a fixed SAMI PCO2 with ODO and PAR at 5 m depth.
