ITP30 was deployed on August 12, 2008 on a 2.4 m thick ice floe in the Beaufort Sea at 75° 54.6 N, 140° 36.9 W 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 A) was also installed. The ITP is configured with a FSI EMCTD and is operating on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
