18DD20160816 - ph

All crs offsets (calculated pH(!)) are negative. Further the total weighted
mean lies below the new adjustment limits (+/- 0.01). Adjust upward
accordingly. Note that all of the more recent cruises show a lower pH though…

18DD20160816 - silicate

All crs offsets indicate slightly too low concentrations… offsets are constant
with depth, too. Clearly visible in each comparison… enough to justify an
adjustment upward.

Posted by nlange@geomar.de on 2021-04-06 11:13:18 UTC for data product: GLODAPv2.2021, v2.2022, v2.2023

18DD20160816 - phosphate

The more recent crs all indicate too low concentrations by about 2 - 3%. However
good fits do exist, e.g. 18DD20080813 or 18DD20040821. Maintain.

Posted by nlange@geomar.de on 2021-04-06 11:13:00 UTC for data product: GLODAPv2.2021, v2.2022, v2.2023

18DD20160816 - nitrate

All crs agree very nicely and indicate 4% too low concentrations. Quite robust
result. Adjust accordingly.

18DD20160816 - oxygen

Crs indicate a bit too high concentrations, but offset is mostly between 1 - 2%
only… further note the relatively large std of the offsets and also the general
inconsistencies with depth… maintain with (small) doubts.
