ITP61 was deployed on a 1.9 m thick icefloe in the Transpolar Drift from the Russian ice camp Barneo in collaboration with the North Pole Environmental Observatory (NPEO) . On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB 28), an US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy (IMB 2013-B), and an US-IABP Polar Area Weather Station (PAWS) were deployed. The ITP operated on a fast sampling schedule of 4 one-way profiles between 7 and 760 m depth each day.
