Data Processing Notes:
----------------------
Oxygen:Dissolved, Fluorescence:URU:Wetlabs and PAR data are nominal and unedited
except that some records were removed at the bottom of many casts.
CTD conductivity and salinity data were bad and were removed from all files.
Extracted chlorophyll samples were available. The comparison of fluorescence values
with chlorophyll looked normal, though fluorescence was much higher in deep water
where 2 chlorophyll samples were near zero.
Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling
for dissolved oxygen. Surface saturation values looked reasonable, but this is a
region subject to great variability.
After cast #31 dissolved oxygen data look bad below the surface with spikes and odd
offset sections. Oxygen:Dissolved:SBE data were removed from CTD casts 32 to 48.
For details on the processing see document: 2023-022_Processing_Report.doc.
