ITP126 was deployed on a 0.95 m ice floe in the Beaufort Sea on September 3, 2021 at 77° 58.5 N, 139° 47.6 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2021 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a prototype Tethered Ocean Profiler (TOP3) was also installed. 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 and includes a fixed SAMI PCO2 with ODO and PAR at 5 m depth.
