49UF20110205 - salinity
Very uncertain crossover results due to the limited depth. The more robust
offsets indicate good accuracy though. Maintain.

49UF20110205 - tco2
Extreme uncertainties in all three crossovers (standard deviations of about +/-
5) making a robust statement impossible. However, data fits ok to RY2011 as do
the other carbonate parameters. Maintain.

49UF20110205 - alkalinity
All four crossovers have a negative offset - varying between -1 up to - 9 even
if (roughly) the same stations are compared. The most recent cruise RY2011 has
the smallest offset. Note that the cruise has no data deeper than 2300m limiting
the crossover quality. Given the high uncertainty and that the weighted mean is
only slightly below -4, maintain.

49UF20110205 - ph
Only three crossovers and all of them indicate clearly a too low pH value
(absolute offset of -0.015). This is only partially confirmed by the additional
interconsistency check (type 2) with an offset of -0.005. Keep in mind the
uncertainty of TA, i.e. adjust to fit well with RY2011.

49UF20110205 - phosphate
There is quite a large variability in the crossover results. The majority of the
cruises (mostly UF and UP cruises) shows a slight positive offset capped to
roughly 2%. Nonetheless other crossovers (especially with NZ cruises) show also
offsets around 0.98. All in all maintain.

49UF20110205 - ph
Only three crossovers and all of them indicate clearly a too low pH value
(absolute offset of -0.015). This is only partially confirmed by the additional
interconsistency check (type 2) with an offset of -0.005. Keep in mind the
uncertainty of TA, i.e. adjust to fit well with RY2011.

49UF20110205 - silicate
All(!) Offsets are clearly within the acceptable range. Less than 10% of the
offsets are below 1. Nonetheless, accurate data as the rest is close to 1.
Maintain.

49UF20110205 - salinity
Very uncertain crossover results due to the limited depth. The more robust
offsets indicate good accuracy though. Maintain.

49UF20110205 - phosphate
There is quite a large variability in the crossover results. The majority of the
cruises (mostly UF and UP cruises) shows a slight positive offset capped to
roughly 2%. Nonetheless other crossovers (especially with NZ cruises) show also
offsets around 0.98. All in all maintain.

49UF20110205 - nitrate
All(!) but one offset clearly within the acceptable range. Accurate data,
maintain.

49UF20110205 - oxygen
Very uncertain crossover results due to the limited depth. The more robust
offsets indicate good accuracy though. Maintain.

49UF20110205 - alkalinity
All four crossovers have a negative offset - varying between -1 up to - 9 even
if (roughly) the same stations are compared. The most recent cruise RY2011 has
the smallest offset. Note that the cruise has no data deeper than 2300m limiting
the crossover quality. Given the high uncertainty and that the weighted mean is
only slightly below -4, maintain.

49UF20110205 - tco2
Extreme uncertainties in all three crossovers (standard deviations of about +/-
5) making a robust statement impossible. However, data fits ok to RY2011 as do
the other carbonate parameters. Maintain.
