The 166 profiles that were recovered from the ITP were processed according to the procedures described in the ITP Data Processing Procedures, and the processing parameters are shown in the figures to the right. Despite the short duration of operation, the profiler experienced 26 software resets (and typically incomplete vertical coverage for the next subsequent profiles) due to the 2007 software bug. This percentage of resets (15%) was superseded by only one other ITP (number 16 encountered 25% resets). On the other hand, the temperature and salinity data are remarkably free of errors (only profile 65 was removed because of corrupted data).
Significant variability in the part of the water column where thermohaline staircases have been observed in the past indicate that perhaps some remnants of these features may have been present early in the time series (profiles 10-50), from which sensor lags could be estimated. These estimates coincided with typical standard lags, so these were applied throughout the series. Rapid drift was a factor at several instances, so that the profiler was unable to climb the wire against the current.
