74AB19871112 - nitrate
Mean offset is approx. +1.2%. Inversions suggest -0.5% to -1.5%. Changes 0.98 to
0.99. This is below threshold, but I believe 0.98 to be too big an adjustment.

Mario and Toste reconsidered this one.
Inversion suggest 0.985, mean of rossovers is 1.025. This cruise is consistently
high.
We suggest to adjust nitrate by 0.98

74AB19871112 - phosphate
Mario and Toste reconsidered
A number of crossovers are very consistent with no correction needed, but others
suggest that a downward adjustment might be needed, particularly for the western
part of the section.
This could suggest that different adjustment should be applied for east and west
part of section, but we don't confident enough for doing this.
We also note the Alvarez et al (2011, JGR) used a correction of 0.98 for this
cruise.

74AB19871112 - phosphate
Offset with 7 cruises: 1.021
Inversion suggests: 0.983
Good xovers with some cruises. Some other cruises, e.g. 316N19941201 and
317519950922 tend to make the offset higher. However, these latter cruises will
be adjusted to higher.
We suggest NO adjustment

74AB19871112 - silicate
Based on new inversion results it was decided on Groeningen to revert the
adjustment.

Bergen meeting 2012: We decided to revise this and follow the inversion and the
mean of the offsets; adjust with 0.97

Mario and Toste
Inversion suggest 0.97 and the mean of the crossovers is 1.028. There is some
inconsistencies in the crossovers that is a bit difficult to explain, but we
suggest to follow the inversion (GLODAP applied -2.7 umol/kg).
We suggest an adjustment of 0.98

No mean offset with 8 cruises: 1.000
Inversion suggests: 0.999
Although there is some spreading of the xover results, there is no justification
for an adjustment.

Surface saturation for CFC12 (113%) higher than for CFC11 (103%), and deviation
in CFC11-CFC12 relationship. These results, in addition to a comparisons with
other cruise, near in time an space, suggest that the CFC12 are too high. We
recommend an adjustment of 0.9.

Mean offset is approx. +1.2%. Inversions suggest -0.5% to -1.5%. Changes 0.98 to
0.99. This is below threshold, but I believe 0.98 to be too big an adjustment.

Based on new inversion results it was decided on Groeningen to revert the
adjustment.

74AB19871112 - cfc11
Surface saturation for CFC12 (113%) higher than for CFC11 (103%), and deviation
in CFC11-CFC12 relationship. These results, in addition to a comparisons with
other cruise, near in time an space, suggest that the CFC12 are too high. We
have recommended an adjustment of CFC12 of 0.9, and thus no adjustment is
recommended for CFC11.

Bergen meeting 2012: We decided to revise this and follow the inversion and the
mean of the offsets; adjust with 0.97

Mario and Toste
Inversion suggest 0.97 and the mean of the crossovers is 1.028. There is some
inconsistencies in the crossovers that is a bit difficult to explain, but we
suggest to follow the inversion (GLODAP applied -2.7 umol/kg).
We suggest an adjustment of 0.98

74AB19871112 - phosphate
Mario and Toste reconsidered
A number of crossovers are very consistent with no correction needed, but others
suggest that a downward adjustment might be needed, particularly for the western
part of the section.
This could suggest that different adjustment should be applied for east and west
part of section, but we don't confident enough for doing this.
We also note the Alvarez et al (2011, JGR) used a correction of 0.98 for this
cruise.

74AB19871112 - nitrate
Mario and Toste reconsidered this one.
Inversion suggest 0.985, mean of rossovers is 1.025. This cruise is consistently
high.
We suggest to adjust nitrate by 0.98

74AB19871112 - oxygen
No mean offset with 8 cruises: 1.000
Inversion suggests: 0.999
Although there is some spreading of the xover results, there is no justification
for an adjustment.

74AB19871112 - phosphate
Offset with 7 cruises: 1.021
Inversion suggests: 0.983
Good xovers with some cruises. Some other cruises, e.g. 316N19941201 and
317519950922 tend to make the offset higher. However, these latter cruises will
be adjusted to higher.
We suggest NO adjustment

74AB19871112 - salinity
Offset with 8 cruises: -0.9 ppm
Inversion suggests: +2.1 ppm
Orig. GLODAP applied slight: +0.2
We suggest NO adjustment
