ITP101 was deployed on a 1.25 m thick ice floe in the Beaufort Sea on September 15, 2017 at 80 53.8 N, 132 23.0 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2017 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy 3 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.
