ITP38 Overview

Deployment Location: 4/19/2010, 11:00 UTC at 88° 39.4’N, 145° 35.7’E

Last Location: 3/17/2011, 1:00 UTC at 66° 12.0’ N, 17° 6.2’ W  

Duration: 332 days

Distance Travelled: 6703 km

Number of profiles: 1011 in 253 days

Other instruments: IMB 2010-A, AOFB 20, PAWS, webcam

ITP 38 was deployed on a 1.7 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 20), an US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (IMB 2010-A), an US-IABP Polar Area Weather Station (PAWS) and NOAA/PMEL webcam were deployed. The ITP operated on a fast sampling schedule of 4 one-way profiles between 7 and 760 m depth each day.  Eleven months after deployment, the tetherless buoy washed ashore on the northern coast of Iceland, was found by a farmer, and later returned to Woods Hole.
