ITP42 Data Description

The ITP profiler was configured to operate with a standard sampling schedule of 2 one-way profiles between 7 and 750 m depth each day. In the surface package, the GPS receiver was powered hourly to obtain locations, and buoy temperature and battery voltage status were recorded.

The buoy drifted slowly south, meandered west and back east before the battery unexpectedly expired in the profiler in April 2011 after only a little over 6 months. The system continued to drift within a 200 km diameter area over the following 4 months for a total of 2583 km, until it was recovered 155 km from the deployment site.

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.
