49UF20100108 - ph

No significant crossovers for this cruise. The interconsistency check (type 2)
shows a strong misfit though (offset of -0.0311).

Posted by nlange@geomar.de on 2018-09-06 11:38:39 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100108 - silicate

The great majority of the crossovers indicate at least 1% too low
concentrations. However, given the limited depth (note the large standard
deviations) the results should be treated with caution. As the absolute
weighted mean offset falls within the acceptable range, maintain.

Posted by nlange@geomar.de on 2018-09-06 11:38:24 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100108 - salinity

The uncertainty in almost all crossovers is extreme. However, the data seems to
fit well to the other cruises. The outlier 32502004 with a weighted offset of
0.065 is a consequence of bad interpolation, thus can be ignored. Maintain.

Posted by nlange@geomar.de on 2018-09-06 11:38:04 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100108 - phosphate

The individual crossover results vary a lot, but the absolute weighted mean
offset is only 1.01. Maintain. Note that the larger offsets are mostly based on
stations at the very southern end of the leg (near PNG).

Posted by nlange@geomar.de on 2018-09-06 11:37:32 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100108 - nitrate

More than 90% of the offsets clearly within the acceptable range. The outliers
are of dubious quality, too. Accurate data, maintain.

Posted by nlange@geomar.de on 2018-09-06 11:37:09 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100108 - oxygen

Difficult analysis as it is based on only 1500m - 2050m. The consenus for this
cruise is quite strong and most crossovers inidcate too high concentrations.
Nonetheless, other cruises with deeper samples show that especially the
"shallower" data is very variable in this region and that offsets in these
depths (1500m - 2000m) can be misleading. Taking the large standard deviations
into account I find it hard to trust the mean offsets. Maintain.

Posted by nlange@geomar.de on 2018-09-06 11:36:51 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100108 - alkalinity

Only 2 crossovers present. The data fits well to 32201992, but shows a weighted
offset of 8.8 (!) to the more recent RY2011 cruise. However it is only one
profile that makes up for most of this high offset. Not enough crossovers for a
full 2nd QC.

Posted by nlange@geomar.de on 2018-09-06 11:36:12 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

49UF20100108 - tco2

Too few data too make a 2nd QC.
