Crossovers indicate nice accuracy. Maintain.

4 out 5 crossovers have offsets clearly within the range. 18SN1994 has slightly
lower concentrations but all within the limits. Note the large standard
deviations though. Maintain.

06AQ20150817 - ph
The crossover analysis is not very trustworthy, as all standard deviations are
at least of the order of +/- 0.005. Further, only 5 crossovers exists in total.
However, it indicates a too high value (offset of 0.0085). The interconsistency
check (type 2) also indicates a too high value with an offset of 0.013 +/-
0.0238, i.e. above the threshold limit but accompanied by a large spread. Given
that both analyses agree quite well adjust downward to achieve "perfect"
interconsistency.

Variable crossover results but the absolute weighted mean is within the 2%
range. Maintain.

All offsets are clearly within the range with vlaues > & < 1. Note that the
cruise data has far less scatter than historic data. Maintain.

06AQ20150817 - silicate
Other Polarstern cruises indicate an ok accuarcy (offsets within a 1.5% range).
However, the two crossovers with Oden cruises (77DN) indicate at least 3% too
high concentrations. Nonetheless, this is not enough for an adjustment.
Maintain.

All crossovers - but 77DN1991 - show offsets below 1. However, only the one
based on 06AQ1987 is slightly below the lower threshold. Especially the good fit
with 06AQ2007 gives confidence about the accuarcy of the data. Maintain.

Even though the surafce saturation ratio is only 90% (probably natural causes),
the good fit between CFC_11 and CFC_12 indicates accurate data. Maintain
