ITP129 was deployed on a 1.0 m thick ice floe in the Transpolar Drift on October 10, 2021 at 81° 32.3 N, 137° 3.3 E in collaboration with the Nansen and Amundsen Basins Observational System (NABOS) project from the Russian Research Vessel Treshnikov. The ITP is operating on a fast sampling schedule of 4 one-way profiles between 5 and 760 m depth each day.
