ITP84 was deployed on a 1.96 m thick ice floe in the Beaufort Sea on October 11, 2014 as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2014 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 and an autonomous atmospheric chemistry buoy (O-Buoy) were also installed. The ITP included a dissolved oxygen sensor and operated on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day and included a fixed SAMI PCO2 and SBE-37 microcat at 6 m depth.
