Only 70 miles from the North Pole, ITP 7 as deployed in April 2007.  The ITP was one component of an IBO installed as a component of the NPEO.

Deployment Location: 4/28/2007, 12:00 UTC at 88° 48.6’N, 12° 30.8’W

Last Location: 2/7/2008, 22:00 UTC at 59° 9.2’ N, 41° 50.2’ W  

Duration: 286 days 

Distance Travelled: 4842 km

Number of profiles: 746 in 186 days

Other instruments: IMB 2007-D, AOFB 11, Weatherex

ITP 7 was deployed on a 2.5 m thick icefloe in the Transpolar Drift 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 separate icefloe approximately 1 km away, a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (IMB 2007-D) and NOAA/PMEL Weatherex station were deployed. The ITP operated on a fast sampling schedule of 4 one-way profiles between 7 and 760 m depth each day, obtaining 746 profiles until the profiler dragged over the East Greenland shelf.  The surface package continued to transmit GPS locations for another 100 days.
