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

18SN20150920 - silicate

Maintain.

Posted by nlange@geomar.de on 2020-03-30 16:46:53 UTC for data product: GLODAPv2.2020, v2.2021, v2.2022, v2.2023

18SN20150920 - salinity

Maintain.

Posted by nlange@geomar.de on 2020-03-30 16:46:41 UTC for data product: GLODAPv2.2020, v2.2021, v2.2022, v2.2023

18SN20150920 - phosphate

Only 1 out of 20 crs offsets is above 1 - all(!) others are at the limit or
cleary below the 2% limit. The offset is present at all depths and independant
of the time of the crs cruise. Adjust according to the weighted mean.

Posted by nlange@geomar.de on 2020-03-30 16:46:31 UTC for data product: GLODAPv2.2020, v2.2021, v2.2022, v2.2023

18SN20150920 - nitrate

Maintain.

Posted by nlange@geomar.de on 2020-03-30 16:46:18 UTC for data product: GLODAPv2.2020, v2.2021, v2.2022, v2.2023

18SN20150920 - oxygen

Tricky decision especially given the region. Many crs show a quite striking
offset indicating too low concentrations (roughly 1%). The offset is present at
all depths and especially visible in comparisons to earlier CCGS Louis S.
St-Laurent (18SN) cruises. However, most weighted offsets are still within the
limit and the fit to the most recent cruise 33HQ20150809 is good. Maintain with
doubts.

18SN20150920 - alkalinity

Again, very uncertain crs results. However, profiles seem to fit ok and the
weighted mean is very close to 0. Maintain.

Posted by nlange@geomar.de on 2020-03-30 16:45:42 UTC for data product: GLODAPv2.2020, v2.2021, v2.2022, v2.2023

18SN20150920 - tco2

Quite uncertain result with large uncertainties present in all crs and only few
crs stations generally. Even though only 1 out of 10 crs offsets is positive
individual comparisons and hence offsets don't seem significant (robust) enough
for a small adjustment. Maintain.
