ITP120 was deployed on a 1.15 m ice floe in the Beaufort Sea on September 21, 2020 at 78 54.0 N, 142 21.2 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2020 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 is operating on a standard sampling schedule of 2 one-way profiles between 5 and 760 m depth each day.
