ITP70 was deployed on a 1.03 m thick icefloe in the Beaufort Sea on August 25, 2013 at 76 55.4 N, 138 50.9 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2013 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB), a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (IMB), an autonomous atmospheric chemistry buoy (O-Buoy) , an Ice-Tethered Micro , and a wave buoy were also installed. The ITP includes a second generation prototype MAVS current sensor operating on a pattern profiling schedule including 2 one-way profiles between 7 and 760 m depth each day and SBE-37 microcat fixed at 6 m depth.
