Data Processing Notes:
----------------------
Conductivity and Fluorescence:URU:Wetlabs data are nominal and unedited except that some records
were removed in editing temperature and salinity.
There was no calibration sampling during this multi-leg cruise, but another time-series cruise that
overlapped with this one, and used the same CTD, did have limited salinity and extracted chlorophyll
sampling and offered some evidence that the CTD fluorescence, temperature and conductivity sensors
were well calibrated.
There was no dissolved oxygen sampling. The calibration of the dissolved oxygen sensors tends to
drift towards lower values, so Oxygen:Dissolved:SBE values are likely low by a few %.
The casts originally saved as events #1 through 9 were renamed as events #106 to 114. This enables
the order of events to match the order of collection.
For details on the processing see document: 2023-064_Processing_Report.doc.
