ITP 50 was deployed on a 3 m thick ice floe in the Transpolar Drift during the ARK-XXVI/3 cruise (TransArc) on the R/V Polarstern as a contribution to the Hybrid Arctic/Antarctic Float Observation System (HAFOS). The ITP included a dissolved oxygen sensor and was programmed to operate on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day. Unfortunately, the underwater profiler did not communicate with the surface unit, so no profile data were obtained.
