Even though all weighted offsets are positive, all - but the one based on K61994
- are clearly within the limits centered around +2. Maintain.

49UP20120602 - alkalinity
The 7 significant crossovers based on only deep data (>2500m) indicate too low
concentrations. 4 of the weighted offsets are below the lower limit centered
around -6. Nonetheless, the absolute mean is within the acceptable range (-3.83)
and if standard deviation are included none of the crossovers has offsets below
the limit. Maintain.

49UP20120602 - ph
The crossovers inidcate a too low value even if the magnitude of the offsets
varies quite a lot (between -0.004 and -0.018. The interconsistency check (type
2) indicates a good fit with the other carbonate data (offset of 0.0035). Given
that the offset with the most recent cruise UP2010 is within the acceptable
range do not adjust.

All offsets lie in the acceptable range with an absolute mean very close to 1.

49UP20120602 - ph
The crossovers inidcate a too low value even if the magnitude of the offsets
varies quite a lot (between -0.004 and -0.018. The interconsistency check (type
2) indicates a good fit with the other carbonate data (offset of 0.0035). Given
that the offset with the most recent cruise UP2010 is within the acceptable
range do not adjust.

49UP20120602 - silicate
All crossovers have an offset between 1.00 and 1.02, all also share relatively
large standard deviations. Maintain.

49UP20120602 - salinity
All(!) crossovers indicate accurate data. Maintain.

49UP20120602 - phosphate
All offsets lie in the acceptable range with an absolute mean very close to 1.
Maintain.

49UP20120602 - alkalinity
The 7 significant crossovers based on only deep data (>2500m) indicate too low
concentrations. 4 of the weighted offsets are below the lower limit centered
around -6. Nonetheless, the absolute mean is within the acceptable range (-3.83)
and if standard deviation are included none of the crossovers has offsets below
the limit. Maintain.

49UP20120602 - tco2
Even though all weighted offsets are positive, all - but the one based on K61994
- are clearly within the limits centered around +2. Maintain.
