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

58JH20120807 - silicate

Crossovers, MLR analyses and depth average all indicate that the concentrations
are too high. Note that the MLR R-squared is relatively low for this parameter.
Anyway given the nice agreement between the MLR and crossover analyses, adjust
downward to fit with the most recent crossover.

Posted by nlange@geomar.de on 2018-09-26 03:58:54 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

58JH20120807 - salinity

The crossovers indicate an "ok" accuracy as does the weighted mean comparison.
Note that the quality of the crossovers is not very high though (this is true
for all parameters). Maintain.

Posted by nlange@geomar.de on 2018-09-26 03:58:25 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

58JH20120807 - phosphate

Crossovers, MLR analyses and depth average all indicate that the concentrations
are too high. Since the MLR R-squared are very low for this parameter the
adjustment follows rather the absolute mean of the crossover offsets - which is
nicely in line with the depth average comparison. Adjust downward.

Posted by nlange@geomar.de on 2018-09-26 03:57:54 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

58JH20120807 - nitrate

Crossovers, MLR analyses and depth average all show that the data is accruate.
Maintain.

Posted by nlange@geomar.de on 2018-09-26 03:57:10 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

58JH20120807 - oxygen

The crossovers as well as an additional MLR analysis indicate slightly too low
data roughly 1% and 1.6% respectively. This is also confirmed by a comparison of
the depth average with the surrounding. Adjust upward.
