ITP43 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.

ITP 43 drifted generally southwest through the Beaufort Gyre region over the short 4 month lifetime of the system. At least one warm core and several cold core halocline eddies were encountered. Suddenly, with no indication of any technical problems, the surface package ceased transmitting via Iridium. Meanwhile, the O-buoy continued to operate until July 2011, the IMB until August 2011 and the AOFB until August 2012. It is unclear whether the ITP suffered a catastrophic hardware failure, or was crushed by the ice.

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.
