ITP78 was deployed on a 1.7 m thick icefloe in the Beaufort Sea on March 11, 2014 at 74 21.6 N, 135 8.3 W as part of the ONR Marginal Ice Zone (MIZ) program. On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB) was deployed. 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.
