The inversion suggest a correction of 1.94 ppm, do not adjust. This is
consistent with CARINA and with IO analysis.

The IO inversion suggest a correction of 1.2 and the mean of the IO crossovers
is -0.9. CARINA suggest 0 correction.
We suggest that no adjustment is applied.

06AQ19960317 - salinity

Average of all cross-overs is: -3.1 ppm (but strongly influenced by 2 very low
cross-overs of cruises 90AV20041104 and 91AA19971204).
Inversion analysis suggests an insignificant adjustment.
Cross-overs with other core cruises (06AQ19920521, 316N19831007) do not warrant
an adjustment.

06AQ19960317 - tco2

The IO inversion suggest a -5 umol/kg adjustment and the mean of the crossovers
is 5.3. CARINA suggest that -4 umol/kg correction.
A careful analysis of the data by van Heuven et al 2011 (DSR-II) suggest an
adjustment of -0.6.
We choose to follow the suggestion of van Heuven, and since this is below the
threshold of 4 umol/kg, we don't apply any adjustment.

06AQ19960317 - phosphate

Existing nutrient data (NO3, NO2, PO4, SIL) was replaced late January 2015 with
new data produced by Karel Bakker (RoyalNIOZ, NL). New data are on single
calibration scale for Polarstern Weddell Gyre cruises 06AQ19960317,
06AQ19980328, 06AQ20050122, 06AQ20080210 and 06AQ20101128. I verified data to be
exceptionally compatible between these five cruises, as well as with other
cruises in the Weddell Gyre. Adjustments for these nutriets for these 5 cruises
will therefore be reverted to 1. As a single exception, I believe the SIL data
for 06AQ19980328 to be biased ~1.5% high despite the normalization effort.

Suggested correction is 1.0255. and mean offset is 0.977. Adjust by 1.02. Not
consistent with CARINA (which has more cruises). Use CARINA adjustment of 1.

This cruise has more crossovers in the AO, so I await those results before

The IO inversion suggest a correction of 1.003 and the mean of the IO crossovers
is 0.99. CARINA suggest a correction of 1.00, and van heuven et al. (2011)
suggest a correction of 1.02. Most crossovers with GLODAP cruises suggest that
an upward adjustment is justified.

Average of all cross-overs is: 0.981 (but this value is strongly influenced by
an anomalous low cross-over with cruise 58A119890214).
Inversion analysis suggests an insignificant adjustment (0.983).
Based on this and the good agreement of phosphate of 06AQ19960317 with that of

Suggested correction is 1.0447, mean bias is 0.96 and it looks low. . This is
larger than CARINA (1.02), and GLODAP (just 0.03). Use CARINA adjustment, this
is based on more data.

GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : Make 1.05. Original Polarstern
Weddell Sea nutrient data have been re-assessed at by Karel Bakker (nuts chemist
at NIOZ) in August 2014. Results (made consistent between cruises using NIOZ
long-term nutrient standards) for SIL are +5% higher than what we currently have
(likely largely due to data handling errors in the past). The improved datasets
will be submitted to Bob Key (expected Nov2014). Untill then, the data we
already have requires 1.05. This is closely in line with earlier suggestions and
the inversion result.

However, silicate of cruise 06AQ19960317 appears to be low against almost all
other cruises with which it has cross-overs, including core cruises.
Inversion analysis by Steven van Heuven appears to confirm the cross-over
result.
At the Paris meeting we therefore suggest an adjustment of silicate for
06AQ19960317 of 1.05

The inversion suggest a correction of 1.0224 based on 9 crossovers with a mean

06AQ19960317 - oxygen

Average of all cross-overs is: 0.984
Inversion analysis suggests an adjustment of 1.030
The analysis is inconclusive. Many cruises appear to support an adjustment, but
some important ones not. As overall oxygen of cruise 06AQ19960317 appears to be
low (av. 0.984) indeed, I suggest a small adjustment.
Therefore, I suggest an adjustment of oxygen for cruise 06AQ19960317 of 1.02

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 an adjustment of 0.992
This indicates that the initial adjustment may have been too high. This is
further corroborated by cross-overs in the Indian sector. Note that the
cross-over results for this cruise are somewhat inconclusive indeed (see above).
Therefore I suggest to modify the adjustment of oxygen to 1.01

06AQ19960317 - cfc12

Tight relationship between CFC11 and CFC12, and consistent (but low) surface
saturation. Thus no adjustment is recommended.

Suface saturation 80%, but same for both CFC11 and CFC12. Relationship between
the CFCs are tight. Thus no adjustment is recommended.
