49UF20120429 - salinity
The analysis with 2000m minimum depth is a lot more robust than the one with
1500m cutoff depth even though only six crossovers (no UF cruise) are present in
the former one. All offsets are in the acceptable range - accurate data.
Maintain.

49UF20120429 - tco2
Only two significant crossovers present. This is not enough for a 2nd QC - note
however that both crossovers (and some of the less significant crossovers too)
indicate slightly too high concentrations.

49UF20120429 - ph
Only two crossovers are present both indicate a too low pH-value. However, the
difference in their offset (-0.025 vs -0.015) is striking. Further does the
interconsistency check (type 2) indicate rather too high concentrations with an
offset of 0.0066 (+/- 0.0098). Not enough for a conclusion.

All but one offset in the acceptable range - even with 1500m minimum depth.
Accurate data at all depth. Maintain.

All offsets are clearly within the acceptable range. An additional analysis with
only comparisons of data deeper 2000m (six cruises) confirms the results.
Maintain.

49UF20120429 - silicate
Also with 1500m minimum depth no crossover has an offset below 1. However,
standard deviations are large and the weighted mean is slightly less strong with
a minimum depth of 2000m. I.e. there is not enough evidence to support an
adjustment below 2%. Maintain.
