ITP125 was deployed on a 0.8 m thick ice floe in the Transpolar Drift on October 1, 2021 at 78 45.0 N, 179 39.4 W in collaboration with the Nansen and Amundsen Basins Observational System (NABOS) project from the Russian Research Vessel Treshnikov. On the same icefloe, a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy 3 was also installed. The ITP includes a dissolved oxygen sensor and is operating on a fast sampling schedule of 4 one-way profiles between 5 and 760 m depth each day.
