Remarks from CTDEDIT:
CTDEDIT was used to remove some records corrupted by shed wakes.
--------------------------------------------------------------------------------------
Data Processing Notes:
----------------------
Conductivity, Transmissivity and Fluorescence are nominal and unedited except
that some records were removed in editing temperature and salinity.
Seapoint Fluorescence values were unbelievably low, likely due to an error in the
gain entered in the configuration file. All values were multiplied by 10. After
recalibration, the comparison between Seapoint fluorescence and extracted chlorophyll
samples exhibited the usual pattern or fluorescence reading higher than extracted
chlorophyl when CHL was <2.5ug/L and lower when CHL was >2.5ug/L.
While the CTD fluorescence data are expressed in concentration units, it is
recommended that users check extracted chlorophyll values where available.
Channel Salinity:T1:C1 was found to be lower than bottles by approximately 0.002psu,
but bottle values are likely a little high due to incomplete flushing of Niskin
bottles and evaporation or desorption of glass particles into samples.
CTD salinity is likely within +/- 0.002psu. No recalibration was applied to salinity.
Dissolved oxygen data were recalibrated in two sections as a large change was
found in comparison with titrated samples between casts #39 and #51.
While calibration drift may be a factor in the change, there was a notable change
in oceanic conditions between 180m and 450m that likely affected the response
of the oxygen sensor.
The SBE DO sensor has a fairly long response time so data accuracy is not as high
when it is in motion as it is during stops for bottles. This will be especially true
when vertical DO gradients are large. To get an estimate of the accuracy of the
SBE DO data during downcasts (after recalibration) a rough comparison was made between
downcast SBE DO and upcast titrated samples. Much of the difference will be due to
problems with flushing of Niskin bottles and/or analysis errors, so the following
statement likely underestimates SBE DO accuracy.
Downcast (CTD files) Oxygen:Dissolved:SBE data for this cruise are considered, very
roughly, to be:
±0.40 mL/L from 0-20db except in areas of very large DO gradients
±0.15 mL/L from 200db-500db
±0.04 mL/L below 500db
The maximum rate of the CTD descent rate was often very high and exceeded 2m/s for
about 25% of the casts; this sometimes appeared to affect data quality.
For details on the processing see the report: 2022-015_Processing_Report.doc.
-------------------------------------------------------------------------
Channel Fluorescence was removed because the values found were extremely low and compared very
badly with extracted chlorophyll samples.
