Composite plot of ITP temperature and salinity profiles.

In addition to the standard SBE41-CP CTD, this unit was the first to include an Integrated Dissolved Oxygen (IDO) sensor which proved to provide much less noisy profile measurements than the SBE 43-F sensor on ITP 6 (which was the only previous ITP to incorporate a DO sensor).

In the surface package, the GPS receiver was powered every hour to obtain locations, and buoy temperature and battery voltage status were recorded.  After 391 days of reliable operation and data telemetry the system stopped transmitting in late summer after apparently being released from the ice in the southwest Beaufort Gyre and drifting in the open ocean for approximately a few weeks.

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.
