ITP20 was deployed on a 3.4 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 B), a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB 16), and a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (IMB 2008-F) were also installed. The ITP included a prototype bio-optical sensor package (PAR, turbidity, fluorescence and CDOM) with dissolved oxygen and was on a delayed pattern sampling schedule that did not begin before the surface package ceased communicating only 6 months after deployment.
