CTDEDIT was used to remove records corrupted by shed wakes near the top and bottom of the cast.. -------------------------------------------------------------------------------------- Data Processing Notes: ---------------------- Conductivity and fluorescence data are nominal and unedited except that some records were removed in editing temperature and salinity. There was no calibration sampling and no useful calibration history from previous cruises. A comparison was made between the cast in Saanich Inlet and a cast from cruise 2021-022 from roughly the same site but 26.5 hours earliers. Unfortunately, this is an area of great variability so little can be concluded except to say that no variable stood out as obviously out of line. The 2 salinity channels differed by 0.006psu. There was no way to determine which of the 2 channels is more accurate. No recalibration was applied.
