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.
Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling
for dissolved oxygen. However, a post-cruise factory calibration suggests values were
low by about 3.5% so that value was used to recalibrate the sensor data.
CTD salinity was found to be low by about 0.01psu in comparison to near-bottom bottles.
A post-cruise factory calibration confirmed that values were low by at least
that much. A correction of +0.01psu was applied.
CTD fluorescence compared with surface extracted chlorophyll samples in the usual way,
with fluorescence higher at low CHL and dropping to about 60% of CHL when CHL>5ug/L.
Fluorescence was not recalibrated.
For details on the processing see document: 2024-005_Processing_Report.doc.
