The first ITP to ever be deployed in open water, ITP 36 is surrounded by ice floes in the marginal ice zone over the Arctic Basin north of the Laptev Sea soon after being released from the ship. (Jeff Pietro)

Two and one half years after deployment, ITP 36 surface package and partial tether was found washed up on the northern shore of Iceland.  Additional data was eventually retrieved from the flash card memory of the surface controller. (Marvin Ingolfsson)

ITP36 was deployed in open water in the Transpolar Drift in collaboration with the Nansen and Amundsen Basins Observational System (NABOS) project from I/B Kapitan Dranitsyn. The ITP operated on a typical sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.  Less than 2 months after deployment, the system completely ceased transmitting, but the surface package with upper 5 m potted tether section was discovered on the north shore of Iceland by the Icelandic Coast Guard in February 2012 and subsequently returned to Woods Hole.
