GLODAPv2 Adjustments

Stations:	[1-last]
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 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:2; CTD salinity data good, setting CTD salinity offset and QC
flag to bottle values.
Oxygen action ID:2; CTD oxygen data good, setting CTD oxygen offset and QC flag
to bottle values.

06AQ20080210 - silicate

Existing nutrient data (NO3, NO2, PO4, SIL) was replaced late January 2015 with
new data produced by Karel Bakker (RoyalNIOZ, NL). New data are on single
calibration scale for Polarstern Weddell Gyre cruises 06AQ19960317,
06AQ19980328, 06AQ20050122, 06AQ20080210 and 06AQ20101128. I verified data to be
exceptionally compatible between these five cruises, as well as with other
cruises in the Weddell Gyre. Adjustments for these nutriets for these 5 cruises
will therefore be reverted to 1. As a single exception, I believe the SIL data
for 06AQ19980328 to be biased ~1.5% high despite the normalization effort.

Autogenerated comment - oxygen

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 1.015. This bring it nicely
in line with contemporanous cruises. Follows Weddell Sea inversion. Mean of ~20
offsets is -1.25%
