ITP105 was deployed on a 1.5 m thick ice floe in the Beaufort Sea on October 6, 2018 at 80° 8.2 N, 141° 43.9 W as part of the Stratified Ocean Dynamics of the Arctic (SODA) project from the USCGC Healy. On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB), and ice mass balance 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 microcats fixed at 5m and 6 m depths.
