ITP49 was deployed on September 11, 2011 on a 2 m thick ice floe in the Transpolar Drift at 84° 22.0 N, 139° 52.6 E 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 includes a dissolved oxygen sensor and will operate on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
