ITP89 was deployed on a 0.5 m thick ice floe in the Beaufort Sea on October 2, 2015 at 79 27.4 N, 148 49.3 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2015 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 , a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB), andan autonomous atmospheric chemistry buoy (O-Buoy) were also installed. The ITP is operating on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
