ITP79 was deployed on a 1.6 m thick icefloe in the Beaufort Sea on March 19, 2014 at 75 24.2 N, 137 11.1 W as part of the ONR Marginal Ice Zone (MIZ) program. 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.
