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

49UF20100524 - ph

Only two signifcant crossovers with huge uncertainties allowing no robust
conclusion. The additional interconsistency check (type 2) does not show any
need for an adjustment though.

Posted by nlange@geomar.de on 2018-09-06 12:25:47 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100524 - tco2

Not enough data present to do a robust 2nd QC.

Posted by nlange@geomar.de on 2018-09-06 12:25:25 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100524 - alkalinity

Only two significant crossovers present. There is a good agreement between them
with both having an offset slightly above 4. Not all less signifcant crossovers
confirm this result though. Also note that the sample depth is limited.

Posted by nlange@geomar.de on 2018-09-06 12:25:16 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100524 - oxygen

The offsets vary in depth and between different cruises. Further, the depth is
limited which can be crucial in this region (especially for oxygen). If the
standard deviations are included only 1 out of 5 cruises has an offset which is
outside the acceptable range. Thus - given the little evidence and large
uncertainty - neglect the absolute weighted mean offset. Maintain.

Posted by nlange@geomar.de on 2018-09-06 12:24:55 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100524 - nitrate

All five crossovers indicate good accuracy. Maintain.

Posted by nlange@geomar.de on 2018-09-06 12:24:13 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100524 - phosphate

Only 4 significant crossovers but all indicate good/ok accuracy. Maybe slightly
too low concentrations. Nonetheless, maintain.

Posted by nlange@geomar.de on 2018-09-06 12:24:00 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100524 - salinity

The crossover analysis is accompanied by a huge uncertainty. Most crossovers
have an "acceptable" offset though. Further, note that the offsets reduce with
depth. Maintain.

Posted by nlange@geomar.de on 2018-09-06 12:23:41 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100524 - silicate

Only 4 deep samples given for comparisons. No 2nd QC possible.

Posted by nlange@geomar.de on 2018-09-06 12:23:23 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
