Remarks from CTDEDIT:
CTDEDIT was used to remove salinity points between 0db and 8.5db.
--------------------------------------------------------------------------------------
Data Processing Notes:
----------------------
Two different CTDs were used during this cruise.
CTD #1091 was used for events #1-139 and the data quality looked good.
CTD #1123 was used for events #149-214 and data quality was lower with unstable
features that were likely due to intermittent flow rate variability.
Oxygen:Dissolved, Conductivity and Fluorescence:URU:Seapoint data are nominal and
unedited except that some records were removed in editing temperature and salinity.
The comparison of CTD salinity with bottle samples was limited to 5m and had a
lot of scatter, but median differences suggest that calibration of sensors used on
both CTDs was reasonably good.
The comparison of dissolved oxygen was limited to 5m where DO values were all high.
No recalibration was applied due to the limitations of the comparison. This was the
first use of this equipment since the sensors were serviced at the factory, so little
calibration drift is expected in salinity, but dissolved oxygen is likely reading
slightly low.
The fluorometer used during events #149 to #214 malfunctioned, so that channel was
removed.
For details on the processing see document: 2022-010_Processing_Report.doc.
