ITP38 Data Description

The ITP profiler was configured to operate with on a fast sampling schedule of 4 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.

The buoy drifted rather slowly towards Fram Strait along the Eurasian side of the Lomonosov Ridge approaching within 30 km of the North Pole on May 23, 2010.  The system then drifted south through the Fram Strait, picked up speed, had difficulty profiling, and significant fouling in the East Greenland current until the profiler stopped communicating on December 24.  The surface package continued to provide GPS locations until mid-March when it washed ashore on the north coast of Iceland.

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.
