ITP 44 surface package effectively corks the 2 foot diameter hole in the ice required for the deployment of the MAVS profiler. (Rick Krishfield)

ITP44 Overview

Deployment Location: 10/9/2010, 01:15 UTC at 75° 51.6’N, 134° 39.7’W

Last Location: 8/22/2011, 23:00 UTC at 76° 57.7’ N, 160° 45.5’ W  

Duration: 318 days

Distance Travelled: 3205 km

Number of profiles: 0 in 1 day

Other instruments: none

ITP 44 was deployed on a 1.5 m thick ice floe in the Beaufort Sea as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2010 cruise on the CCGS Louis S. St. Laurent. The ITP included a prototype MAVS current sensor and was scheduled to operate on a pattern profiling schedule including 2 one-way profiles between 7 and 760 m depth each day.  However, communications between the underwater and surface unit failed after the first partial down profile, presumably due to a hardware problem with the inductive modem circuit.
