49UP20120410 - ph

The crossover analysis does not allow a robust conclusion given the large
standard deviations and additional variability. The interconsistency check
(type 2) shows a strong positive bias of 0.0105 +/- 0.0106. All in all, too
strong uncertainties to give any adjustment.

49UP20120410 - silicate

The four signifcant crossovers, based on a minimum depth of 2500m, indicate
accurate data - only one offset is above 1.01. Maintain.

49UP20120410 - salinity

All(!) crossovers indicate accurate data. Maintain.

49UP20120410 - phosphate

All 5 significant crossovers have offsets very close to 1. The results are
robust (minimum depth of 2500m). Maintain.

49UP20120410 - nitrate

All offsets - but one - lie in the acceptable range very close to 1. Maintain.

49UP20120410 - oxygen

All 7 crossovers indicate accurate data. This result is relatively robust as the
minimum depth is set to 2500m. Maintain.

Posted by nlange@geomar.de on 2018-09-21 15:20:07 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UP20120410 - alkalinity

The 5 significant crossovers based on only deep data (>2500m) show quite a lot
of variability with offsets ranging from +5 to -8. 4 out of 5 weighted offsets
are negative though. Nonetheless, the absolute mean is within the acceptable
range (-2.96). Maintain.

49UP20120410 - tco2

All 5 crossovers indicate slightly too high concentrations. However, only 2
offsets are above the upper limit and all share (still) relatively large
standard deviations. Maintain.
