ITP51 Data Description

The ITP profiler was configured to operate 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 hourly, and buoy temperature and battery voltage status were recorded.

After deployment, the buoy first headed slightly south and west, then turned and meandered eastward toward Severnaya Zemlya (North Land).  Unfortunately, the system approached too close to the continental shelf on October 24, dragged the mooring, and contact with the profiler was lost the following day.

The surface package continued to broadcast locations for another 14.5 months as it drifted over deep water across the Transpolar Drift northwards to more than 88 °N, then turned and proceeded through Fram Strait.  The last location from ITP51 was obtained on January 11, 2013, and 2 days later the last transmission from the surface package was received.

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.]
