ITP76 was deployed on a 1.7 m thick icefloe in the Transpolar Drift on April 11, 2014 at 89 9.7 N, 177 35.6 E as part of the North Pole Environmental Observatory (NPEO) . On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB), an US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy , and an US-IABP Surface Velocity Program (SVP) were deployed. The ITP is operating on a fast sampling schedule of 4 one-way profiles between 7 and 760 m depth each day.
