All crossovers indicate a nice accuracy. However, the concentrations seem
slightly too low, but not enough for an adjustment. Maintain.

All but two crossovers show accepatble offsets centered around 0. Further, there
is a very nice match with 49NZ2009. Maintain.

320620140320 - ph
Here, pH crossover results and results from the carbon inter consistency check
(type 2) do not support each other.
Even if one neglects the crossovers of 318M1994, 32501994 and 32502006 the
weighted mean offset is still below -0.005. However, a very nice
interconsistency (combined with the good crossover results for TA and tco2)
indicates good accuracy (offset of -0.0026). Based on the uncertainty resulting
from these two, I suggest no adjustment. Maintain.

The mean weighted offsets shows 1% too high concentrations. Nonetheless,
crossovers with an offset <1 exist as well. Also, there is a good agreement with

320620140320 - ph
Here, pH crossover results and results from the carbon inter consistency check
(type 2) do not support each other.
Even if one neglects the crossovers of 318M1994, 32501994 and 32502006 the
weighted mean offset is still below -0.005. However, a very nice
interconsistency (combined with the good crossover results for TA and tco2)
indicates good accuracy (offset of -0.0026). Based on the uncertainty resulting
from these two, I suggest no adjustment. Maintain.

320620140320
PH data is excluded, because it is not calculated for a constant temperature.

320620140320 - cfc11
The analysis shows the typical deviations from the atmospheric equilibrium
towards Antarctica. Further north the reached equilibrium indicates that the
data is accurate. Maintain.

320620140320 - silicate
The mean weighted offsets shows 1% too high concentrations. Nonetheless,
crossovers with an offset <1 exist as well. Also, there is a good agreement with
the NZ cruises. Maintain.

320620140320 - salinity
All crossovers indicate a nice accuracy. However, the concentrations seem
slightly too low, but not enough for an adjustment. Maintain.

Except for 3250 (being a bad crossover example) offsets indicate a very good

All crossover offsets are clearly within the acceptable range. No need for an
adjustment.
