The great majority of the crossovers indicate a very nice accuracy. Outliers are
based on stations close to Greenland, i.e. disregard those ones. Maintain.

33RO20130803 - tco2
Many crossovers older 14 years show offsets above the limit - especially the
ones in the northernmost parts of the cruise track. However, (all of) the more
recent cruises have very small offsets indicating a nice accuracy. Thus, the
high offsets are probably the cause of natural signals. Maintain.

33RO20130803 - ph
Both the crossover analysis and the interconsistency check (type 2) result in
offsets below the threshold of +/- 0.1. Latter indicates also precise
measurements. The carbon parameters match almost perfectly. Clearly no need for
an adjustment.

Most crossovers show offsets within the 2% range. The few strong outliers are
all based on stations very close to iceland. Ignore outliers and maintain.

Most crossovers show only very small offsets - this is nicely reflected in the
absolute mean. The few strong outliers are all based on stations very close to

A tricky analysis as uncertainties a very high, see standard deviations of
weighted offsets. Further, even the more robust offsets show a great variability
ranging from 0.98 to as high as 1.1. The absolute weighted mean is close to
unity and clearly within the limits though. Maintain.

33RO20130803 - cfc12
Slightly oversaturated but within the limits. Note the nice fit with CFC_11
data. Maintain.

33RO20130803 - ph
Both the crossover analysis and the interconsistency check (type 2) result in
offsets below the threshold of +/- 0.1. Latter indicates also precise
measurements. The carbon parameters match almost perfectly. Clearly no need for
an adjustment.

33RO20130803 - silicate
A tricky analysis as uncertainties a very high, see standard deviations of
weighted offsets. Further, even the more robust offsets show a great variability
ranging from 0.98 to as high as 1.1. The absolute weighted mean is close to
unity and clearly within the limits though. Maintain.

33RO20130803 - salinity
The great majority of the crossovers indicate a very nice accuracy. Outliers are
based on stations close to Greenland, i.e. disregard those ones. Maintain.

33RO20130803 - phosphate
Most crossovers show offsets within the 2% range. The few strong outliers are
all based on stations very close to iceland. Ignore outliers and maintain.

33RO20130803 - nitrate
Most crossovers show only very small offsets - this is nicely reflected in the
absolute mean. The few strong outliers are all based on stations very close to
iceland. Ignore outliers and maintain.

33RO20130803 - oxygen
Most crossovers have offsets below 1. However, seldom offsets exceed 1%.
Maintain.

33RO20130803 - tco2
Many crossovers older 14 years show offsets above the limit - especially the
ones in the northernmost parts of the cruise track. However, (all of) the more
recent cruises have very small offsets indicating a nice accuracy. Thus, the
high offsets are probably the cause of natural signals. Maintain.
