Composite plot of ITP temperature and salinity contours.


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.  After 416 days, the ITP surface package and profiler were recovered after the system had completed a nearly 1000 km meridional section, along a 3900 km staggered path, transecting the Beaufort Gyre.  For several profiles while the CTD salinity sensor was fouled beyond use, the temperature sensor likely detected a significant warm core eddy (close to 1° C) centered around 100 m.

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.
