WHOI Ice Tethered Profiler #3

Deployed on August 23, 2005, this unit completed 1532 profiles of salinity and temperature over 382 days. The third ice-tethered profiler (ITP) was deployed in the Beaufort Sea on 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. ITP3 and a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy were deployed on a 3.5 m thick multiyear ice floe in a location designed to drift through the Beaufort Gyre Freshwater Experiment (BGFE) array during the following year. The ITP unit operated on a fast sample schedule of 4 one-way profiles between 10 and 760 m depth each day until the unit was damaged during an attempted recovery operation the following summer.
