ITP92 was be deployed on a 1 m thick ice floe in the Transpolar Drift on September 12, 2015 at 80 41.9 N, 166 28.0 E in collaboration with the Nansen and Amundsen Basins Observational System (NABOS) project from the Russian Research Vessel Treshnikov. On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB), an autonomous atmospheric chemistry buoy (O-Buoy) , 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 microcat fixed at 6 m depth.
