74DI19921222 - salinity
Inversion suggested correction of 3.57 ppm, based on 9 crossovers with mean
offset of -1.755. Do not adjust.

74DI19921222 - salinity
Average of all cross-overs is: erroneous because of spurious cross-over with
cruise 31WT19841001.
Inversion analysis suggests an insignificant adjustment.
Cross-over with core cruises (316N19831007, SAVE, 323019940104) suggest that no
adjustment be needed.

close to existing. Note that although high against almost all cruises, it is 5%
low against 323019940104, which itself is supposedly good. Why? Xover is at the
very beginning of each cruise. 323019940104 seems to have been about 5% high in
its earliest stations (approx 1-35, from then on accurate?).

74DI19921222 - nitrate
Suggested correction is 0.9835, and mean bias was 1.036. This cruise appears a
bit high, we recommend to adjust it by a factor of 0.98. Slightly larger than
GLODAP suggestion, 0.12 vs 0.5 umol/kg. Our recommendation is consistent with
CARINA

Average of all cross-overs is: 1.041 ; but this values is strongly influenced by
one anomalously high cross-over with cruise 31WT19841001.
Inversion analysis (without cruise 31WT19841001) suggests no significant
adjustment (0.988).
I suggest NO adjustment of nitrate for cruise 74DI19921222

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 nitrate by 0.973
Although there is variability in the region of cross-overs, the cross-overs with
core cruise 49NZ20031106 suggests that an adjustment is warranted.
I therefore suggest an adjustment of nitrate by 0.98

The inversion suggest correction of 1.0142 and mean offset is 1.053. This is
shifted up because of huge offset with 31WT19841001, which covers a narrow depth
range at Brazil slope only. Do not adjust. Consistent with CARINA.

Average of all cross-overs is: 1.054 (but this values is strongly influenced by

Inversion analysis (without anomalous cruise 31WT19841001) suggests no
significant adjustment (1.005).
Cross-overs with core cruises do not support an adjustment either.
I suggest NO adjustment of silicate for cruise 74DI19921222.

74DI19921222 - oxygen
Inversion suggested a x1.0173 ~1.02 correction. This is based on 9 xovers with
mean offset 0.983. This is a SA cruise and from the xovers a 1.02 correction
appears very reasonable. Initially recommend that these data are corrected by
1.02. This is ~consistent with CARINA, 1.015. Use CARINA adjustment.

Average of all cross-overs is: 0.968 (but this values is strongly influenced by

Inversion analysis (without anomalous cruise 31WT19841001) suggests a small
adjustment amounting to 1.016
Cross-overs with core cruises do suggest that cruise 74DI19921222 be somewhat
low.
Based on this evidence I suggest an adjustment of oxygen for cruise 74DI19921222
amounting to 1.015

74DI19921222 - oxygen
Inversion suggested a x1.0173 ~1.02 correction. This is based on 9 xovers with
mean offset 0.983. This is a SA cruise and from the xovers a 1.02 correction
appears very reasonable. Initially recommend that these data are corrected by
1.02. This is ~consistent with CARINA, 1.015. Use CARINA adjustment.

74DI19921222 - silicate
The inversion suggest correction of 1.0142 and mean offset is 1.053. This is
shifted up because of huge offset with 31WT19841001, which covers a narrow depth
range at Brazil slope only. Do not adjust. Consistent with CARINA.

74DI19921222 - phosphate
Inversion suggested correction was 1.0469 and MO is 0.991. MO pulled up by
crossover 74DI19921222 / 31WT19841001! Appears in fact low. Recommend adjust x
1.04. Same as CARINA and similar to GLODAP.

74DI19921222 - nitrate
Suggested correction is 0.9835, and mean bias was 1.036. This cruise appears a
bit high, we recommend to adjust it by a factor of 0.98. Slightly larger than
GLODAP suggestion, 0.12 vs 0.5 umol/kg. Our recommendation is consistent with
CARINA

74DI19921222 - salinity
Inversion suggested correction of 3.57 ppm, based on 9 crossovers with mean
offset of -1.755. Do not adjust.

74DI19921222 - salinity
Average of all cross-overs is: erroneous because of spurious cross-over with
cruise 31WT19841001.
Inversion analysis suggests an insignificant adjustment.
Cross-over with core cruises (316N19831007, SAVE, 323019940104) suggest that no
adjustment be needed.

74DI19921222 - oxygen
Average of all cross-overs is: 0.968 (but this values is strongly influenced by
one anomalously high cross-over with cruise 31WT19841001).
Inversion analysis (without anomalous cruise 31WT19841001) suggests a small
adjustment amounting to 1.016
Cross-overs with core cruises do suggest that cruise 74DI19921222 be somewhat
low.
Based on this evidence I suggest an adjustment of oxygen for cruise 74DI19921222
amounting to 1.015

74DI19921222 - silicate
Average of all cross-overs is: 1.054 (but this values is strongly influenced by
one anomalously high cross-over with cruise 31WT19841001).
Inversion analysis (without anomalous cruise 31WT19841001) suggests no
significant adjustment (1.005).
Cross-overs with core cruises do not support an adjustment either.
I suggest NO adjustment of silicate for cruise 74DI19921222.

74DI19921222 - phosphate
Average of all cross-overs is: 0.990 (but this has been influenced by an
anomalously high cross-over with cruise 31WT19841001)
Inversion analysis suggests an adjustment of 1.035 (without anomalous cruise
31WT19841001)
Comparison with core cruises (316N19831007, 323019940104, SAVE) appear to
confirm that phosphate of this cruise is too low.
I suggest an adjustment of phosphate for cruise 74DI19921222 of: 1.04

74DI19921222 - nitrate
Average of all cross-overs is: 1.041 ; but this values is strongly influenced by
one anomalously high cross-over with cruise 31WT19841001.
Inversion analysis (without cruise 31WT19841001) suggests no significant
adjustment (0.988).
I suggest NO adjustment of nitrate for cruise 74DI19921222

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 nitrate by 0.973
Although there is variability in the region of cross-overs, the cross-overs with
core cruise 49NZ20031106 suggests that an adjustment is warranted.
I therefore suggest an adjustment of nitrate by 0.98
