ITP63 Data Description

The ITP profiler was configured to operate on a fast sampling schedule of 4 one-way profiles between 7 and 510 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.

From its deployment location by NP-39 north of the Canadian Archipelago at 83.5° N, ITP 63 drifted generally ENE from 115° to 85° W longitudes for the first 9 months, headed SSW for the next few winter months, then largely shifted within the region 82-83° N, 95-105° W for the remainder of its drift. The frequent CTD profiles were absent of any significant eddies and did not vary a great amount over time.

Nearly 1.5 years after deployment, with no apparent reason, the surface package of the ITP ceased communicating via Iridium in mid-October 2013.

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.
