ITP77 was deployed on a 2.0 m thick icefloe in the Beaufort Sea on March 9, 2014 at 73 21.9 N, 134 59.2 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.
