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 Was part of the Beaufort Gyre Exploration Project (whoi.edu) 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, an Ice Tethered Micro 3 Data (whoi.edu) (ITM 3), and a wave buoy were also installed. The ITP included 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 a SBE-37 microcat fixed at 6 m depth. Two years later, ITP70 was completely recovered in the Beaufort Sea from the CCGS Louis S St. Laurent during the JOIS 2015 cruise.
