ITP7 was deployed on a 2.5 m thick icefloe in the Transpolar Drift on April 28,2007 at 88.810N, 12.513W as part of the North Pole Environmental Observatory (NPEO) . On the same icefloe, a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB) and Climate Change College meteorological mast were also installed. On a seperate icefloe approximately 1 km away, a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (ARC 5756) and NOAA/PMEL Weatherex station were deployed. The ITP is operating on a fast sampling schedule of 4 one-way profiles between 7 and 760 m depth each day.
