ITP 93 Final Data
Data Description
The ITP profiler was configured to operate on a pattern profiling schedule with different summer and winter schedules. In the summer (between March 1 and October 31), the instrument conducted a 1.5 day repeating pattern of an up profile from 750 to 7 m, followed by 4 one-way (down, up, down, up) profiles between 7 and 200 m, followed by a down profile from 7 to 750 m, all spaced 6 hours apart. In the winter (between November 1 and February 28 or 29), the instrument conducted a 3 day repeating pattern of an up profile from 750 to 7 m, followed 6 hours later by a down profile from 7 to 200 m, followed 24 hours later by an up profile from 200 to 7 m, followed 6 hours later by a down profile from 7 to 750 m, followed by a 36 hour gap before the pattern repeated. The complicate scheme was designed to conserve battery power to extend the lifetime of the instrument, while maximizing the acquisition of the bio-optical data during the summer months. In the surface package, the GPS receiver was powered hourly to obtain locations hourly, and buoy temperature and battery voltage status were recorded.
The plots to the right are of the final, calibrated, edited data (as opposed to the raw data presented on the active instrument pages).
