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).

Shortly after the over-the-side deployment of ITP 37, the surface package bobs on the surface before the edge of the ice pack. (Jeff Pietro)

For the surface buoy to be removed, scientists from the Norwegian Polar Institute Centre for Ice, Climate and Ecosystems (ICE) had to amputate the wire where it was frozen into the ice. (Photo courtesy of Nalan Koe)
