49UP20130801 - salinity
Almost all "high quality" crossovers have a slight (roughly -0.0018) negative
offset, clearly within the acceptable range. Only two of the "high quality"
crossovers show a positive offset, 32501985 and 49UP2002. The good consensus is
quite striking. Nonetheless, I doubt that an adjustment of 0.0018 is adviceable
in any case (note also the standard deviations which are at least of the same
order). Maintain.

Most crossovers indicate too high concentrations, but the uncertainty is quite
large (typical standard deviation of +/- 2.5). Not clear enough for an
adjustment within the range. Maintain.

Crossovers cover nicely the entire cruise track. All offsets, but the one with
49YR2011, fall clearly within the acceptable range. Positive and negative
offsets exist independant of location and time. Maintain.

The majority of the offsets are less than 2%. The few crossovers having an
offset greater than 2% are again UF and UP cruises with often lmited crossover
quality, e.g. 49UF20040616. However, there is clearly no evidence for an
adjustment.

49UP20130801 - ph
Quite a variety of offsets combined with large standard deviations emphasize the
uncertainty. Nonetheless, the weighted mean as well as most of the individual
offsets are clearly within the acceptable range. The additional
interconsistency check (type 2) shows an offset of 0.0067 +/- 0.009, hence also
acceptable. Maintain.

Many crososvers are present and all(!) offsets are within the acceptable range.
There is no clear agreement on a small bias either. Maintain.
Note that the data of most UF cruises are limited to roughly 2500m.

All (!) offsets are within the acceptable range, most of them show offsets below
1%. Note for example the very nice match with 49NZ20051031. Only one "reliable"
offset (49UF20040421) indicates slightly too high concentrations. All other
crossovers indicate either the opposite or simply match very well. Maintain.

Most crossovers have a good quality and indicate accurate data. Exempt from this
statement are many crossovers with UF- and UP cruises which also form the
majority of the "outliers" / offsets with relatively large standard deviation,
e.g. UP2005. Maintain.

49UP20130801 - cfc11

49UP20130801 - tco2
Most crossovers indicate too high concentrations, but the uncertainty is quite
large (typical standard deviation of +/- 2.5). Not clear enough for an
adjustment within the range. Maintain.
Posted by nlange@geomar.de on 2018-09-06 14:24:13 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20130801 - alkalinity
Crossovers cover nicely the entire cruise track. All offsets, but the one with
49YR2011, fall clearly within the acceptable range. Positive and negative
offsets exist independant of location and time. Maintain.
Posted by nlange@geomar.de on 2018-09-06 14:23:53 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20130801 - oxygen
Most crossovers have a good quality and indicate accurate data. Exempt from this
statement are many crossovers with UF- and UP cruises which also form the
majority of the "outliers" / offsets with relatively large standard deviation,
e.g. UP2005. Maintain.
Posted by nlange@geomar.de on 2018-09-06 14:23:26 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20130801 - nitrate
Many crososvers are present and all(!) offsets are within the acceptable range.
There is no clear agreement on a small bias either. Maintain.
Note that the data of most UF cruises are limited to roughly 2500m.
Posted by nlange@geomar.de on 2018-09-06 14:22:59 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20130801 - phosphate
The majority of the offsets are less than 2%. The few crossovers having an
offset greater than 2% are again UF and UP cruises with often lmited crossover
quality, e.g. 49UF20040616. However, there is clearly no evidence for an
adjustment.
Posted by nlange@geomar.de on 2018-09-06 14:22:36 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20130801 - salinity
Almost all "high quality" crossovers have a slight (roughly -0.0018) negative
offset, clearly within the acceptable range. Only two of the "high quality"
crossovers show a positive offset, 32501985 and 49UP2002. The good consensus is
quite striking. Nonetheless, I doubt that an adjustment of 0.0018 is adviceable
in any case (note also the standard deviations which are at least of the same
order). Maintain.

49UP20130801 - silicate
All (!) offsets are within the acceptable range, most of them show offsets below
1%. Note for example the very nice match with 49NZ20051031. Only one "reliable"
offset (49UF20040421) indicates slightly too high concentrations. All other
crossovers indicate either the opposite or simply match very well. Maintain.

49UP20130801 - ph
Quite a variety of offsets combined with large standard deviations emphasize the
uncertainty. Nonetheless, the weighted mean as well as most of the individual
offsets are clearly within the acceptable range. The additional
interconsistency check (type 2) shows an offset of 0.0067 +/- 0.009, hence also
acceptable. Maintain.
