ITP13 was deployed as part of an Ice-Based Observatory (IBO) in the Beaufort Sea as part of the Beaufort Gyre Observing System (BGOS) during the summer JOIS 2007 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (IMB 2007-F) and a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB 12) were also installed. The ITP included a dissolved oxygen sensor and operated on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
