ITP59 was deployed on a 1.5 m thick ice floe in the Transpolar Drift in collaboration with the Nansen and Amundsen Basins Observational System (NABOS) project from the Russian Research Vessel Federov. On the same icefloe, a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (IMB 2013-H), an autonomous atmospheric chemistry buoy (O-Buoy 9), a meteorological buoy, and Uptempo buoy were also installed. The ITP includes a dissolved oxygen sensor and operated on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day and a fixed SAMI pCO₂ with SBE-37 microcat at 6 m depth.
