ITP 70 Data Processing

The 3712 profiles that were transmitted from the ITP were processed according to the procedures described in the ITP Updated Data Processing Procedures. The processing parameters are shown in the figures to the right. The processing procedures for the MAVS current probe are described in Cole et al. (2015).

The CTD and velocity sensors obtained excellent data for over 323 days after deployment until the battery expired due the enhanced profiling schedule.

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.
