35MF19981205 - nitrate

OISO3: two deep profiles (at 30°S and 56°S).
Note: these 2 stations are treated as different cross overs in the analysis
below.
INTERNAL OISO CONSISTENCY:
10 cross overs were analyzed. The average of all cross overs is 1.031
(+/-0.051).
2 cross overs found at 30°S show no significant differences (<2%) and involve
cruises that are thought to have no offset in nitrate. When the offsets
suggested for the other cruises are taken into account the average of the 4
cross overs found at 30°S is 1.010 (+/-0.003). This suggests that no adjustment
would be required.
At 56°S, however, all cross overs show significant differences and 2 of them
involve cruises that are thought to have no offset in nitrate. When the
suggested offsets are taken into account as well as the suggested natural
variability, the average of the 6 cross overs found at 56°S is 1.055 (+/-0.004).
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 1.024 (+/-0.009)
and since INDIGO1 is thought to have no offset in nitrate, this supports the
result of the analysis above.
The cross over with the cruise INDIGO3 (56°S) shows a ratio of 1.095 (+/-0.021),
but INDIGO3 is thought to have low nitrate values. When the suggested offset is
taken into account as well as the suggested natural variability, a good
agreement is found with the analysis above (1.058).
CONCLUSION:
The different results obtained at 30°S and 56°S are probably due to natural
changes that would have operate in Antarctic deep waters as suggested by the
analysis of other parameters including salinity.
Based on this I suggest no adjustment for nitrate.

35MF19981205 - oxygen

OISO3: only one deep profiles (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 1.027 (+/-0.027).
All cross overs show significant differences (>1.01), and 4 of them involve
cruises that are thought to have no offset in oxygen. When the offsets suggested
for the other cruises are taken into account the average of all cross overs is
1.014 (+/-0.003). This suggests that an adjustment of 0.99 could be required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO3 shows a ratio of 1.017 (+/-0.008), which
supports the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest an adjustment of 0.99 for oxygen.

35MF19981205 - silicate

OISO3: two deep profiles (at 30°S and 56°S).
Note: these 2 stations are treated as different cross overs in the analysis
below.
INTERNAL OISO CONSISTENCY:
11 cross overs were analyzed. The average of all cross overs is 0.976
(+/-0.045).
Only one cross overs found at 30°S show no significant differences (<2%) and
involve a cruise that is thought to have no offset in silicate. When the offsets
suggested for the other cruises are taken into account the average of the 5
cross overs found at 30°S is 0.956 (+/-0.004). This suggests that an adjustment
of 1.04 could be required.
At 56°S, however, 2 cross overs show no significant differences (<2%), one of
them involving a cruise that is thought to have no offset in silicate. When the
offsets suggested for the other cruises as well as the suggested natural
variability are taken into account the average of all the 6 cross overs found at
56°S is 0.982 (+/-0.002). This suggests that a small adjustment would be
required, but it is not warranted since Antarctic deep waters are entitled to
natural variability which could play a role in the differences observed at 56°S.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 0.969 (+/-0.014),
which is in good agreement with the analysis above (given that INDIGO1 is
thought to have slightly low silicate).
The cross over with the cruise INDIGO3 (56°S) shows a ratio of 0.918 (+/-0.007),
but INDIGO3 is thought to have high silicate values. When the suggested offset
is taken into account as well as the suggested natural variability, a good
agreement is found with the OISO analysis above (0.987).
CONCLUSION:
The different results obtained at 30°S and 56°S are probably due to natural
changes that would have operate in Antarctic deep waters as suggested by the
analysis of other parameters including salinity.
Based on this I suggest an adjustment of 1.04 for silicate.

35MF19981205 - alkalinity

OISO3: two deep profiles (at 30°S and 56°S).
Note: these 2 stations are treated as different cross overs in the analysis
below.
INTERNAL OISO CONSISTENCY:
9 cross overs were analyzed. The average of all cross overs is +1.3 (+/-4.3)
umol/kg.
All cross overs but 1 show no significant differences (<5 umol/kg) and involve
cruises that are thought to have no offset in alkalinity. This suggests that no
adjustment would be required.
Note that cross overs found at 56°S show a large scatter around the mean (+3.2
+/-2.9 umol/kg), probably due to natural variability. And indeed, if a decrease
in alkalinity of 1 umol/kg/yr is assumed (as suggested in this study) the
scatter and the mean are reduced (+0.9 +/-1.9 umol/kg/yr).
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show differences
of -16.2 (+/-1.3) umol/kg and -11.5 (+/-4.5) umol/kg, respectively, but INDIGO1
is known to have high alkalinity values by about 16 umol/kg and INDIGO3 would
have no offset but alkalinity might have decreased by about 12 umol/kg. If this
is taken into account the offsets with INDIGO cruises translate into no
significant differences, which supports the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for alkalinity.

35MF19981205 - tco2

OISO3: two deep profiles (at 30°S and 56°S).
Note: these 2 stations are treated as different cross overs in the analysis
below.
INTERNAL OISO CONSISTENCY:
11 cross overs were analyzed. The average of all cross overs is +0.6 (+/-4.4)
umol/kg.
6 cross overs show no significant differences (<4 umol/kg) and involve cruises
that are thought to have no offset in TCO2. When the offsets suggested for the
other cruises are taken into account the average of all cross overs is -0.5
(+/-2.7) umol/kg. This suggests that no adjustment would be required.
Note however that different offsets are found at 30°S (-3.1 +/-1.3 umol/kg)
compared to the 56°S (+1.7 +/-0.8 umol/kg). This difference could be attributed
to natural variability as suggested by the analysis of salinity data.
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show differences
of -12.1 (+/-3.4) umol/kg and -4.3 (+/-3.0) umol/kg, respectively. But since the
cruises INDIGO1 and INDIGO3 are known to have high TCO2 values by about 10
umol/kg and 6 umol/kg, respectively (according to this study and GLODAP), the
differences translate into no significant offsets (-2 umol/kg and +2 umol/kg,
respectively). This supports the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for TCO2.

35MF19981205 - salinity

OISO3: two deep profiles (at 30°S and 56°S).
Note: these 2 stations are treated as different cross overs in the analysis
below.
INTERNAL OISO CONSISTENCY:
11 cross overs were analyzed. The average of all cross overs is -9.6 (+/-9.6)
ppm.
All cross overs show negative offsets ranging from -2 to -35 ppm, the largest
offset resulting from comparison with cruises 35MF20010103 and 35MF20040103
which are thought to have high salinity values. When the suggested offsets are
taken into account the average of all cross overs is -6 (+/-4) ppm.
It should be noted, however, that larger offsets are found at 56°S (mean of -8
+/-3 ppm), compared to 30°S (-2.4 +/-0.7 ppm).
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of
-4 (+/-9) ppm and -11 (+/-3) ppm, respectively, which supports the analysis
above.
CONCLUSION:
Different results are obtained north or south of the Polar Front which should be
attributed to natural variability that is more likely to happen in Antarctic
deep waters than in Subtropical deep waters.
Based on this I suggest no adjustment for salinity.
