ITP111 was deployed on a 2.8 m thick ice floe in the Transpolar Drift on October 5, 2019 in collaboration with the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition from the Russian Research Vessel Federov. On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB), a Seasonal ice mass balance buoy, a Meteorological sled, Spectral radiometer and AWI snow buoy were also installed. The ITP operated on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
The following August 2020, ITP 111 was completely recovered floating in the marginal ice zone of the East Greenland Current from the R/V Polarstern during the recovery leg of the MOSAiC expedition. The profiler was covered in mud so had dragged on the shelf.
