St. Laurent. The ITP operated on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day, nearly completely encircling the perimeter of the Beaufort Gyre anticyclonic circulation cell in two years. Until July 30, 2008, the ITP profiler transmitted the information via the inductive modem (IM) and Iridium, but ceased for no apparent reason.\u00a0 Location data was still being obtained and transmitted by the surface package so that when the system was recovered in October 2009 (during JOIS 2009), an additional 800 profiles were recovered from the underwater unit. \u00a0Only about half of these include complete profiles because in early 2009 the instrument dragged on the Chukchi\/Northwind topography and became inverted and tangled on the tether (as recovered).\u00a0 Several hours after recovery,\u00a0<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/data\/completed-missions\/itp-32\/\">ITP32\u00a0<\/a>was deployed in the same hole from which ITP8 was recovered, only a short distance from the edge of the 2.5 m thick icefloe.<\/p>\n\t\t\t\t<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/08\/DSCN4450_106239.jpg\" target=\"_self\" rel=\"noopener\">\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/08\/DSCN4450_106239.jpg\" alt=\"ITP 8 is found slightly snow covered but intact (except for polar bear scratch marks) two years after deployment at a nearby location.\" height=\"3072\" width=\"2304\" title=\"DSCN4450_106239\" \/>\n\t\t\t\t<\/a>\n\t\tITP 8 is found slightly snow covered but intact (except for polar bear scratch marks) two years after deployment at a nearby location.
