The ITP profiler was configured to operate with an accelerated sampling schedule of 3 one-way profiles between 7 and 750 m depth each day as it was expected to drift out in only 2 years based on its deployment location. In the surface package, the GPS receiver was powered every hour to obtain locations, and buoy temperature and battery voltage status were recorded. After 213 days (and 643 profile attempts) of reliable operation and data telemetry, the ITP profiler stopped sending data when the instrument likely parted with the surface buoy. The surface package continued to transmit GPS locations and status for another 886 days, when the 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.
