CTDEDIT was used to remove records from the top 0.2m and some records near the bottom of the cast. -------------------------------------------------------------------------------------- Data Processing Notes: ---------------------- Oxygen:Dissolved, Conductivity and Fluorescence:URU:Wetlabs data are nominal and unedited except that some records were removed in editing temperature and salinity and a few unbelievably high surface fluorescence values were padded in events #2 and #57. Oxygen:Dissolved:SBE values could not be confirmed as there was no calibration sampling for dissolved oxygen. However, a post-cruise factory calibration shows values to be consistently low by about 3.6%, so that value was used to recalibrate the sensor data. A post-cruise factory calibration confirmed that salinity values were low by at least 0.011psu. A correction of +0.011psu was applied.
