ITP65 was deployed on a 1.52 m thick ice floe in the Beaufort Sea as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2012 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB 24), a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy (IMB 2012-L), an autonomous atmospheric chemistry buoy (O-Buoy 7) and an Ice-Tethered Micro (ITM 1) were also installed. The ITP includes a dissolved oxygen sensor and full biosuite system and a fixed SAMI pCO2 with SBE-37 microcat at 6 m depth and is operating on a pattern profiling sampling schedule including one full one-way profile between 7 and 760 m depth every 1.5 days.
