ITP72 was deployed on a 1.25 m thick ice floe in the Transpolar Drift on August 30, 2013 in collaboration with the Nansen and Amundsen Basins Observational System (NABOS) project from the Russian Research Vessel Federov. The ITP included a dissolved oxygen sensor and full biosuite system, operated on a pattern profiling sampling schedule including one full one-way profile between 7 and 760 m depth every 1.5 days and included a fixed SAMI PCO2 and SAMI pH at 6 m depth.
