ITP128 was deployed on a 1.36 m thick ice floe in the Transpolar Drift on September 30, 2021 at 77 26.5 N, 179 54.3 E 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 is operating on a fast sampling schedule of 4 one-way profiles between 5 and 760 m depth each day.
