WHOI Ice Tethered Profiler #1

This unit was deployed August 15, 2005 and completed 2043 profiles of salinity and temperature over 511 days. The second ice-tethered profiler (ITP) that was fielded was ITP1, which was deployed in the Beaufort Sea as part of the Beaufort Gyre Observing System (BGOS) during the Joint Western Arctic Climate Study (JWACS) 2005 cruise on the Canadian Coast Guard Ship (CCGS) Louis S. St. Laurent. ITP 1 and a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy were deployed on a 4.6 m thick multi-year ice floe in a location designed to drift through the BGOS array over the following year. The profiler unit operated until it exhausted its memory on 8 January 2007, but the surface unit continued to provide status enabling the system to be recovered the following summer during the Joint Ocean Ice Study (JOIS) 2007 cruise.
