06MT20101014 - salinity
Only 4 crossovers, 3 of them within the acceptable range. Maintain even though
concentrations might be too low.

06MT20101014 - phosphate
The deep water average of this cruise fits quite nicely to the GLODAPv2 average
of the surrounding cruises (1.45 μmol kg−1 vs 1.46 μmol kg−1). The MLR offset
(15 samples) is in line with that, too. Maintain.

06MT20101014 - nitrate
The deep water averages indicate good accuracy (21.44 μmol kg−1 vs 21.63 μmol
kg−1). Two MLR analyses support this result (based on 15 and 21 samples), as
does the Redfield ratio. Maintain.

06MT20101014 - silicate
However, silicate values has been used to check the nitrate and silicate.

06MT20101014 - silicate
The deep water average of this cruise is 34.78 μmol kg−1, whereas the GLODAPv2
average of the surrounding cruises is 35.63 μmol kg−1, i.e. 2.44% higher. Two
MLR (note their rel. large RMSE) also indicate too high concentrations but
differ strongly in the magnitude, even though the predictor variables seem all
fine. Note the large range obtained from the 15 (21) individual sample offsets.
All in all, silicate is very likely too low but it is not possible to obtain a
robust adjustment.

Only 3 crossovers, but all clearly within range. An additional MLR Analysis
confirms the results. Maintain.

06MT20101014 - cfc12
The majority of stations show reasonable saturation ratios, which are clearly
within the 5% tolerance.
Following the total mean ratio of 0.99 +/- 0.05 no adjustment needed.
