ITP130 was deployed on a 0.6 m thick ice floe in the Beaufort Sea on September 25, 2022 at 77° 45.6 N, 140° 1.2 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2022 cruise on the CCGS Louis S. St. Laurent. The ITP is operating on a fast sampling schedule of 4 one-way profiles between 5 and 760 m depth each day.
