06AQ19920521 - tco2
06AQ19920521 689
tco2
There are 5 xovers. The fitted offset is -2.9. The suggested adjustment is 0
All residuals fits very close to 0 and keep inside +-5.
Very good fit with 4 GLODAP cruises

All xovers and output of inversions are refered on figure: "Report plot for
adjustments"
Real diff (Green dots) are the differences taken directly from xover routines.
The complete segment of error bar represents the xover standard deviation.
Yellow line stand for the offset calculated for this cruise.
Black stars stand for the offset calculated for the others cruises in the
xovers.
Blue squares stand for the Fitted differences that would be obtained from the
calculated offsets (Yellow line - black stars)
Red dots stand for the Residuals between the 'Real diff'(Green dots) and 'Fitted
diff' (Blue squares)
c suffix in the upper X axis labels stand for Core Cruises

06AQ19920521 - nitrate
Average of all cross-overs is: 1.037
Inversion analysis suggests an adjustment of: 0.969
Core cruises tend to show less difference with 06AQ19920521
Therefore I suggest the minimum adjustment of nitrate for cruise 06AQ19920521
amounting to 0.98

06AQ19920521 - phosphate
Average of all cross-overs is: 0.988
Inversion analysis suggests an adjustment of: 0.959
Core cruises (e.g. 316N19831007) tend to show no difference with 06AQ19920521
At the Paris meeting we agreed to apply NO adjustment to phosphate of cruise
06AQ19920521.

UPDATE
A new inversion analysis has been done (13 Oct. 2008), now with data to which
all suggested adjustments from the first round were applied. This new analysis
suggests a significant adjustment of phosphate by 0.98
Comparing regional cross-overs a small adjustment seems justified.
Therefore, I suggest an adjustment of phosphate by 0.98

06AQ19920521 - silicate
Average of all cross-overs is: 1.075 (but this value is strongly influenced by
an anomalously high cross-over with cruise 316N19831113)
Inversion analysis appears to be strongly influenced by this.
Comparison with core cruises and other reliable cruises tends to show silicate
of 06AQ19920521 to be somewhat on the high side.
I suggest an adjustment of silicate for cruise 06AQ19920521 of 0.98

06AQ19920521 - oxygen
Average of all cross-overs is: 1.018
Inversion analysis suggests no significant adjustment (0.999)
Based on this I suggest to follow the inversion result and thus NO adjustment of
oxygen for cruise 06AQ19920521
