ITP98 was deployed on a 0.7 m thick ice floe in the Beaufort Sea on September 29, 2016 at 78 34.2 N, 130 3.6 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2016 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB 34) and a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy 2 were 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.
