323019940104 - silicate

The inversion suggest a correction of 0.9827 and the mean offset is 1.017, and
the data do look a bit high, (there are also 23 valid crossovers from the
southwest atlantic, where this cruise took place). I believe this and recommend
that an adjustment of 0.98 is applied to these data. A high bias of 1.6 was
determined in GLODAP and the x0.98 adjustment is consistent with the adjustment
recommended in CARINA.

323019940104 - silicate

UPDATE
A new inversion analysis for the Southern Ocean data 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 0.976
-
Both initial inversion analyses for the North Atlantic and Southern Ocean data
sets did suggests a significant adjustment, but we decided not to follow it (see
other comments). However, after the new inversion analysis, an adjustment is
still suggested.
We therefore suggest a small adjustment of silicate by 0.98

This cruise is in GLODAP. The analysis by Gouretski and Jancke (PiO, 2001)
sugggest an adjustment of 0.06 umol/kg.
The N/P ratio is 15.27, intercept -0.79.
The average of all cross overs is 1.002
The inversion suggest an adjustment of 0.96 and 0.98 for WLSQ and WDLSQ,

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

323019940104 - silicate

Average of all cross-overs is 0.990 (Southern Ocean) and 1.000 (North Atlantic).
Inversion analysis suggests an adjustment of 0.976 (Southern Ocean) and 0.967
(North Atlantic).
The results are inconclusive. I notice that the mean cross-overs results are
strongly influenced by two cruises (29HE20010305, 29HE20020304) with low
cross-overs (and large standard deviations). Cross-over with core cruise
49NZ20031106 does not warrant an adjustment.
At the Paris meeting we agreed on NO adjustment of silicate of cruise
323019940104.

323019940104 - phosphate

Average of all cross-overs is 1.007 (Southern Ocean) and 1.001 (North Atlantic).
Inversion analysis suggests no significant adjustment for either of the two
regions.
Cross-overs with core cruises do not support an adjustment.
I suggest NO adjustment of phosphate for cruise 323019940104.

323019940104 - nitrate

Average of all cross-overs is: 1.002
Inversion analysis (Southern Ocean) suggests no significant adjustment (0.993);
on the other hand, inversion analysis for the North Atlantic does suggest a
slight adjustment of 0.977
Cross-overs with core cruises (49NZ20031106, 74JC19950320, SAVE) do not support
an adjustment - those with 29HE20020304 show a very large standard deviation,
and thus is not significant.
Based on all this I suggest NO adjustment of nitrate for cruise 323019940104.

323019940104 - oxygen

The average of all cross overs is 0.997.
The inversions suggest no adjustment.
The cross-overs with other core cruises do not support that an adjustment is
warranted.
Based on this I suggest no adjustment to the oxygen values.
