ITP29 Data Description

The ITP profiler operated on 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 745 days of reliable operation and data telemetry while the system drifted across the Arctic Ocean with the Transpolar Driftstream current, the ITP profiler stopped communicating with the surface package when the mooring system presumably dragged in shallow bathymetry off of the northeast corner of Greenland.  The surface package continued drifting with the East Greenland current to the Labrador Sea for nearly another year acquiring GPS locations and status data before transmissions ceased.

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.
