ITP42 Data Processing

The 386 profiles that were transmitted and recovered from the ITP were processed according to the procedures described in the ITP Updated Data Processing Procedures.  The processing parameters for ITP 42 are shown in the figures to the right.  Buoy drift speeds infrequently exceeded 30 cm/s so the profiler covered the full extent of over 98% of the profiles.  The CTD sensors were largely free of fouling, providing over 90% good data return.

Thermohaline staircases were present at the beginning and end of the time series, enabling CTD lag corrections. All of the lags were in the typical range as previous systems and did not vary significantly.  Potential conductivity exhibited some small spikes on 2 down profiles and larger shift over 6 other consecutive profiles.  In general, the data quality is excellent over the short record.
