33HQ20150809 - alkalinity

No crossovers present. But a comparison of the depth average of this cruise
versus surrounding cruises (2300 μmol kg−1 vs 2298 μmol kg−1) indicates accurate
data. Additional MLR analyses Support this finding. Note the very low R-squared
values... Maintain.

33HQ20150809 - tco2

No crossovers present. But a comparison of the depth average of this cruise
versus surrounding cruises (2153 μmol kg−1 vs 2158 μmol kg−1) indicates
"acceptable" data. Additional MLR analyses (here only the one with a R-squared
value above 0.4 included) actually indicates quite accurate (even slightly too
high) concentrations. Maintain.

Posted by nlange@geomar.de on 2018-08-21 14:54:34 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

33HQ20150809 - ph

A carbon inter consistency check (type 2) indicates that the pH data fits nicely
to TA and tco2 data (showing a mean offset of 0.0022). Maintain.

Posted by nlange@geomar.de on 2018-07-27 10:50:19 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

33HQ20150809 - cfc11

The data seems to be just on the acceptable limit. Maintain.

33HQ20150809 - cfc12

The data seems to be just on the acceptable limit. Maintain.

Posted by nlange@geomar.de on 2018-06-14 14:46:18 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

33HQ20150809 - silicate

All offsets, but the one of 06AQ1996 (not reliable), are above 1. Note that
18HS1993 is also not too reliable, as the crossover-stations are very close to
the coast. The other offsets are either just above the upper limit or within the
acceptable range. Maintain.

Posted by nlange@geomar.de on 2018-06-14 14:43:13 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

33HQ20150809 - salinity

All crossovers show only very small Offsets. Maintain.

Posted by nlange@geomar.de on 2018-06-14 14:38:22 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

33HQ20150809 - phosphate

The results of the crossovers seem to be dependant on the region. I.e.
crossovers in the west show no or positive offsets (e.g. 77DN1991), whereas
crossovers based on stations in the east show negative offsets (e.g. 32PZ2002 -
even below the limit). Given this "pattern" and that the weighted mean is within
the acceptable range no adjustment suggested.

Posted by nlange@geomar.de on 2018-06-14 14:37:06 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

33HQ20150809 - nitrate

18HS1994 is the only crossover with an offset above 1. It is based on only few
measurements of stations relative close to the coast, i.e. it is not too
reliable. The other offsets (except one outlier) are consistently between 0.99
and 1 indicatingh good accuracy. Maintain.

Posted by nlange@geomar.de on 2018-06-14 14:31:02 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021

33HQ20150809 - oxygen

All crossovers, except for 77DN1991, indicate too low concentrations. 49NZ2004
was strongly adjusted upward (?)...
Nevertheless, not enough evidence for a small adjustment.
