The selected Calculated Carbon Parameter has been dismissed in October 2017! Legacy values will be exported as is and displayed in red with subscript "c", e.g. -0.123456_c! No data available? Insert -999 No suggestion for adjustment possible? Insert -888 To calibrate CTDsal use: CTDsal_calibrated = (CTDsal - CTDsal_intercept) / CTDsal_slope To calibrate CTDoxy use: CTDoxy_calibrated = (CTDoxy - CTDoxy_intercept) / CTDoxy_slope

Autogenerated update by AV for pH

Bulk update requested by Anton Velo on 2015-06-04 including comments with
reasoning (src: ph_adjustments_g2_sent_carsten_20150604.xlsx / 2015-06-04): Make
0.013 (decrease legacy adjustment of 0.018 by 0.005 units). Xovers/Inversion of
calculated TCO2 from TALK and pH suggest that legacy adjustment was a bit high,
so decrease it to fit better

Autogenerated CTD salinity and CTD oxygen update

Automated update! This overwrites adjustment values (and flags) of CTDoxy and
CTDsal with the values from BOTsal and BOToxy for every cruise, unless CTDsal
(or CTDoxy) is not present or bad.
Salinity action ID:5; CTD salinity data good, setting CTD salinity offset and QC
flag to bottle values.
Oxygen action ID:6; CTD oxygen data good, setting CTD oxygen offset and QC flag
to bottle values.
