The ITP profiler was configured to operate with a standard sampling schedule of 2 one-way profiles between 7 and 750 m depth each day.  In the surface package, the GPS receiver was powered hourly to obtain locations, and buoy temperature and battery voltage status were recorded.  After 419 days of reliable operation and data telemetry (including six weeks in a lead, marginal ice or open water), the ITP profiler stopped communicating with the surface package.  Less than two weeks later, the surface package ceased transmitting GPS locations and status.

The plots to the right are of the final, calibrated, edited data (as opposed to the raw data presented on the active instrument pages).

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.
