Remarks from CTDEDIT:
CTDEDIT was used to remove a few surface records and a few records
corrupted by shed wake.
--------------------------------------------------------------------------------------
Data Processing Notes:
----------------------
Station Names contain the transect number followed by the station number for that transect.
There was no calibration sampling, but the CTD had been calibrated at the
factory in February 2021, so significant drift is not expected.
For details on the processing see document: 2022-078_Processing_Report.doc.
