49UP20140703 - salinity
Most of the reliable (i.e. excluding all UP and UF cruises) crossovers indicate
an acceptable accuracy. Note that NZ2000 is not a high quality crossover either.
Also note that especially the other NZ cruises have a negative offset in depth
of around -0.0025. But this offset cannot be found that clearly in the other
crossovers. Maintain.

49UP20140703 - tco2
Based on in total 4 significant crossovers. All of those have an offset of at
least 2. However, all corresponding standard deviations are at least as large as
+/- 2. Given that all fall clearly within the range and only 4 crossovers are
given, there is not enough evidence to justify an adjustment below 4. Maintain.

49UP20140703 - alkalinity
Based on in total 4 significant crossovers. 49K61994 and 49NZ2005 have both a
negative offset of roughly -2. Contrary to those 318M2004 has a positive offset
of 2 and 32501993 fits nicely. I.e. all crossovers indicate an acceptable
accuracy with no clear consensus on a potential bias. Insignificant crossovers
confirm this result. Maintain.

All offsets of reliable crossovers fall clearly within the acceptable range. The
crossovers with UF and UP cruises are of minor quality as only "shallow"
measurements are compared. Accurate data, maintain.

49UP20140703 - ph
Based on in total 4 significant crossovers. The offsets vary quite strongly and
are accompanied by a relative high uncertainty. The interconsistency check (type
2) would imply a slight downward adjustment, but given that this is not
confirmed by the crossovers and TCO2 data might not bee completly accurate,
maintain.

All offsets fall clearly within the acceptable range. The crossovers with UF and
UP cruises are of minor quality as only "shallow" measurements are compared.
Most other crossovers with more "recent" cruises, e.g. 318M2004, indicate about
0.5% - 1% too low concentrations. However, by far not enough evidence to justify
such an adjustment. Maintain.

Again the UF and UP crossovers are of limited quality, as is NZ2000. The rest
indicates good accuracy, e.g. note the nice fit with NZ20051031. Maintain.

The offsets diminish in the deeper parts of the water column, i.e. many UF and
UP crossovers are not very trustworthy and should be ignored (note also their
high standard deviations). Most other crossovers have offsets quite close to 1.
Maintain.

All saturation ratios show a clear oversaturation of (in the mean) 10%. CFC12
does not show this oversaturation, as reflected in the mean regression residual
of -0.10. Based on this I suggest to adjust it accordingly.

49UP20140703 - cfc11
Following discussion in Seattle we changed this to no adjustment
Posted by siv.lauvset@uib.no on 2018-10-01 10:42:37 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20140703 - tco2
Based on in total 4 significant crossovers. All of those have an offset of at
least 2. However, all corresponding standard deviations are at least as large as
+/- 2. Given that all fall clearly within the range and only 4 crossovers are
given, there is not enough evidence to justify an adjustment below 4. Maintain.
Posted by nlange@geomar.de on 2018-09-06 15:20:38 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20140703 - alkalinity
Based on in total 4 significant crossovers. 49K61994 and 49NZ2005 have both a
negative offset of roughly -2. Contrary to those 318M2004 has a positive offset
of 2 and 32501993 fits nicely. I.e. all crossovers indicate an acceptable
accuracy with no clear consensus on a potential bias. Insignificant crossovers
confirm this result. Maintain.

49UP20140703 - oxygen
The offsets diminish in the deeper parts of the water column, i.e. many UF and
UP crossovers are not very trustworthy and should be ignored (note also their
high standard deviations). Most other crossovers have offsets quite close to 1.
Maintain.
Posted by nlange@geomar.de on 2018-09-06 15:19:32 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20140703 - nitrate
All offsets fall clearly within the acceptable range. The crossovers with UF and
UP cruises are of minor quality as only "shallow" measurements are compared.
Most other crossovers with more "recent" cruises, e.g. 318M2004, indicate about
0.5% - 1% too low concentrations. However, by far not enough evidence to justify
such an adjustment. Maintain.

49UP20140703 - phosphate
All offsets of reliable crossovers fall clearly within the acceptable range. The
crossovers with UF and UP cruises are of minor quality as only "shallow"
measurements are compared. Accurate data, maintain.

49UP20140703 - salinity
Most of the reliable (i.e. excluding all UP and UF cruises) crossovers indicate
an acceptable accuracy. Note that NZ2000 is not a high quality crossover either.
Also note that especially the other NZ cruises have a negative offset in depth
of around -0.0025. But this offset cannot be found that clearly in the other
crossovers. Maintain.

49UP20140703 - silicate
Again the UF and UP crossovers are of limited quality, as is NZ2000. The rest
indicates good accuracy, e.g. note the nice fit with NZ20051031. Maintain.
Posted by nlange@geomar.de on 2018-09-06 15:17:56 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023
49UP20140703 - ph
Based on in total 4 significant crossovers. The offsets vary quite strongly and
are accompanied by a relative high uncertainty. The interconsistency check (type
2) would imply a slight downward adjustment, but given that this is not
confirmed by the crossovers and TCO2 data might not bee completly accurate,
maintain.

49UP20140703 - cfc11
All saturation ratios show a clear oversaturation of (in the mean) 10%. CFC12
does not show this oversaturation, as reflected in the mean regression residual
of -0.10. Based on this I suggest to adjust it accordingly.

49UP20140703 - cfc12
Based on the saturation ratio only the data seems to be fine. Maintain.
