09AR19950717 - silicate

x-overs with 09AR19980228, 49HH19941213 and 49HH20011127 are those that have
relatively few data points of these three cruises (09AR19950717 has many more
data points for these x-overs). Exactly these x-overs are high compared to the
others.
If we give less weight to these three cruises, the adjustment would be higher
than 1.025; I suggest 1.03

09AR19950717 - silicate

09AR19950717 - oxygen

Only bottle data used, as CTD data does not fit nicely (even after a linear fit
has been applied).
Most crossovers indicate an accuracy with deviations smaller 0.5%. Only one
outlier showing an offset below 0.99 (AR1998). AR1998 itself might have too high
concentrations according to previous crossover results. No adjustment needed.

09AR19950717 - silicate

Good agreement between the crossovers. Except for one outlier (49HH2001 -
doubtful quality of analysis) all offsets below the threshold limit of 0.98.
Following the mean offset of 0.975, apply adjustment of 1.025.

09AR19950717 - phosphate

All crossovers clearly within the acceptable range, the offsets are at least to
2% accurate. No adjustment needed.

09AR19950717 - salinity

All offsets - but two - within acceptable range. Mean offset almost exactly
zero. Fits also well to AR1996. No need for an adjustment.
