ITP94 was deployed on a 0.9 m thick ice floe in the Transpolar Drift on October 7, 2019 in collaboration with the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition from the Russian Research Vessel Federov as a contribution to the Hybrid Arctic/Antarctic Float Observation System (HAFOS). On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB), a Seasonal ice mass balance buoy, a Meteorological sled, Spectral radiometer and AWI snow buoy were also installed. The ITP included a dissolved oxygen sensor and bio-optical sensors and operated on a pattern profiling sampling schedule including one full one-way profile between 7 and 760 m depth every 1.5 days.
The following August 2020, ITP 94 was completely recovered floating in the marginal ice zone of the East Greenland Current from the Russian R/V Akademik Tryoshnikov which was supporting the rotation of personnel and equipment to the MOSAiC .
