Remarks from CTDEDIT:
CTDEDIT was used to remove some records corrupted by shed wakes; salinity was cleaned lightly.
--------------------------------------------------------------------------------------
Data Processing Notes:
----------------------
Oxygen:Dissolved, Transmissivity, Conductivity and Fluorescence:URU:Wetlabs data are
nominal and unedited except that some records were removed in editing temperature and
salinity.
The comparison of dissolved oxygen was limited to 5m where DO values were mostly high.
No recalibration was applied due to the limitations of the comparison. This was the
second use of this equipment since the sensors were serviced at the factory.
Dissolved oxygen is likely reading slightly low.
Similarly, no recalibration was applied to salinity due to the small number of samples,
all of which came from 5m.
Pressure was very accurate at the surface.
For details on the processing see document: 2022-011_Processing_Report.doc.
