Remarks from CTDEDIT:
CTDEDIT was used to remove some records corrupted by shed wakes near
the top of the cast; salinity was cleaned.
---------------------------------------------------------------------------------
Data Processing Notes:
----------------------
Conductivity and Fluorescence data are nominal and unedited except that some
records were removed in editing temperature and salinity.
NOTE: While the CTD fluorescence data are expressed in concentration units, they
do not always compare well to extracted chlorophyll samples, particularly for
casts far from shore.
The only data available for event #66 came from the soak period so they have not
been processed.
There was no calibration sampling during this cruise. Recalibration of dissolved
oxygen data was based on an intercomparison with an SBE911 on one cast during a
previous cruise. This is considered a rough estimate.
Salinity was not recalibrated; rough comparisons during 2 previous cruises suggest
it is within +/-0.005psu.
For details on the processing see document: 2018-090_Processing_Report.doc.
