The ITP profiler was configured to operate with an accelerated sampling schedule of 4 one-way profiles between 10 and 750 m depth each day in order to more quickly evaluate endurance and component fatigue. In the surface package, the GPS receiver was powered every two hours to obtain locations, and buoy temperature and battery voltage status were recorded. Both operated reliably for 382 days until the system was destroyed. The battery voltage of the profiler had been dropping sharply at the end, and would not have likely been able to power the profiler for much longer.
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.
