ITP137 was deployed on a 1.0 m ice floe in the Beaufort Sea on September 24, 2022 at 79 49.1 N, 139 58.1 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2022 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a Tethered Ocean Profiler (TOP6) and a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy 3 were also installed. The ITP includes a dissolved oxygen sensor, is operating on a fast sampling schedule of 4 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.
