ITP 76 Data Description

The ITP profiler was configured to operate on a fast sampling schedule of 4 one-way profiles between 7 and 760 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.

ITP 76 drifted south with the Transpolar Drift and through Fram Strait before the mooring dragged on the East Greenland shelf and communications with the underwater unit ceased after 241 days. The surface package continued south for another 3 months before ceasing Iridium communications in the Denmark Strait.

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.
