Remarks from CTDEDIT:
CTDEDIT was used to remove some near-surface records and records
corrupted by shed wakes at the bottom of the cast; salinity was cleaned.
--------------------------------------------------------------------------------------
Data Processing Notes:
----------------------
Conductivity, Transmissivity and Fluorescence are nominal and unedited except
that some records were removed in editing temperature and salinity.
The SBE DO sensor calibration changed during a previous use in 2022. No
change was noted during this cruise, though the correction (based on comparison
with titrated samples) is larger than normally seen for this type of 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:
±0.25 mL/L from 0-100db except in areas of very large DO gradients
±0.07 mL/L from 100db-150db
±0.02 mL/L below 150db
For details on the processing see the report: 2022-067_Processing_Report.doc.
-------------------------------------------------------------------------
Channel Fluorescence was removed because the values found were extremely low and compared very
badly with extracted chlorophyll samples.
