Remarks from CTDEDIT:
CTDEDIT was used to remove surface records and a few records corrupted
by shed wakes near the bottom of the cast.
Data Processing Notes:
----------------------
Dissolved Oxygen and Fluorescence are nominal and unedited, except
that some records were removed in editing temperature and salinity.
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. It is suggested that extracted chlorophyll values be
checked where available.
Comparison with bottles suggests that the CTD salinity is reasonably close to bottle
salinity for both conductivity sensors, but there is a large scatter and flushing of
Niskin bottles is likely incomplete. No recalibration was applied.
There was no dissolved oxygen calibration sampling, so the recalibration used for
cruise 2017-01 was applied to these data since the same sensor was used and
calibration sampling was extensive.
For details on the processing see processing report: 2017-07-proc.doc.
