Remarks from CTDEDIT:
CTDEDIT was used to remove a few near-surface records and a few records
corrupted by shed wakes near the bottom of the cast.
--------------------------------------------------------------------------------------
Data Processing Notes:
----------------------
Oxygen:Dissolved, Conductivity, PAR and Fluorescence:URU:Wetlabs data are nominal and
unedited except that some records were removed in editing temperature and salinity.
There were only 6 salinity calibration samples taken during this cruise, of which only 3 were
below 5m. THe deep samples were lower than bottle salinity by 0.003psu or less, and low by up to
0.006psu allowing for incomplete flushing of NIskin bottles. The differences are much larger
for the surface samples, but differences in timing of CTD and bottle sampling and high local
salinity gradients make these comparisons unsuitable for calibration checks.
Salinity is likely good to +/-0.005psu.
Extracted chlorophyll samples were mainly gathered at the surface using a bucket, but 3 samples
came from a Niskin bottle at 5m. CTD fluorescence data are spiky above 1m, so CTD data for
comparison were drawn from about 1.5 to 2m. The ratio of CTD Fluorescence to Extracted CHL samples
was somewhat lower than usual for surface samples, but for the samples from 5m the fluorescence
was about 70% of the CHL samples. The ratio of fluorescence to CHL dropped with increasing CHL,
as is usually seen from these sensors. The sensor appears to have performed well.
Oxygen:Dissolved:SBE values cannot be confirmed as there was no calibration sampling for
dissolved oxygen. Surface saturation values were between 60% and 180% with all values <100%
coming from areas where vertical mixing may be strong.
For details on the processing see document: 2024-029_Processing_Report.doc.
