ITP22 was deployed on a 3.5 m thick ice floe in the Beaufort Sea as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2008 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a Scottish Association for Marine Science (SAMS) Ice Mass Balance Array (SIMBA C) was also installed. The ITP operated on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day, but only 13 profiles were transferred in a single burst over a month after the profiler was installed.
At 82° N, ITP 22 was the northernmost ITP deployed in the Beaufort Gyre during JOIS 2008. In the distance, the Louis is barely visible through the fog. (Photo by Rick Krishfield)
