ITP 37 was deployed in open water in the Transpolar Drift in collaboration with the Nansen and Amundsen Basins Observational System (NABOS) project from I/B Kapitan Dranitsyn. The ITP operated on a typical sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.  After sampling across the Arctic Eurasian basins for 16 months, the buoy grounded in northeast Svalbaard, and the surface package was recovered on May 7, 2011 on a helicopter survey from  the RV Lance by scientists from the Norwegian Polar Institute Centre for Ice, Climate and Ecosystems (ICE).
