ITP 67 Data Description

The ITP profiler was configured to operate with a pattern profiling schedule, but communications between the underwater and surface unit failed after the first partial down profile. In the surface package, the GPS receiver was powered hourly to obtain locations, and buoy temperature and battery voltage status were recorded. The ITP drifted generally northwestward until October 27, 2014 when the surface package ceased Iridium transmissions (presumably due to the surface package being pushed below the sea ice). Nearly 2 years later on August 29, 2016 the surface package resurfaced 400 km south of its previous last location, resumed sending locations while drifting eastward prior to recovery.

The plots to the right are of the final location and status data.

See the Data Products tab to the left for descriptions of the three levels (I, II, III) of data processing and to access all data.
