The quality of upcast data is considered lower than downcasts due to the CTD passing through waters disturbed by the cable and CTD. However, for many casts there was strong vertical mixing leading to narrow ranges of variables so that the errors are likely small. Fluorescence and dissolved oxygen data are nominal and unedited, except that some records were removed in editing temperature and salinity. There was no salinity calibration sampling and no other information available on which to base a recalibration. For details on the processing see processing report: 2016-32-proc.doc. ---------------------------------------------------------------------------------- !--1--- ---2---- ---3--- ---4---- --5--- --6-- -7-- !Pressu Temperat Fluores Salinity Oxygen Oxyge Numb !re ure: cence: :T0:C0 : n: er_o !
