35MF20010103 - salinity
OISO6: 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 +6.1 (+/-9.0)
ppm.
9 cross overs show significant differences (>5 ppm) and involve cruises that are
thought to have no significant offset in salinity. When the offsets suggested
for the other cruises are taken into account the average of all cross overs is
+7.6 (+/-2.5) ppm. It should be noted, however, that lower offsets are found at
56°S (mean of +6 +/-1 ppm) compared to 30°S (mean of +10 +/-1 ppm).
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of
+10 (+/-9) ppm and +3 (+/-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 an adjustment of -10 ppm for salinity.

35MF20010103 - tco2
OISO6: 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 +1.4 (+/-3.9)
umol/kg.
7 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 +0.3
(+/-3.1) umol/kg. This suggests that no adjustment would be required.
It should be noted, however, that larger offsets are found at 30°S (+2.9 +/-1.3
umol/kg), compared to 56°S (-1.8 +/-2.3 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 offsets of
-8.4 (+/-4.6) umol/kg and -5.1 (+/-2.0) 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. This supports no adjustment.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for TCO2.

35MF20010103 - alkalinity
OISO6: 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 -2.0 (+/-3.7)
umol/kg.
All cross overs but 2 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 (-3.0
+/-2.8 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 is reduced (-2.8 +/-1.2 umol/kg).
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show differences
of -17.0 (+/-1.3) umol/kg and -14.7 (+/-3.0) 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 14 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.

35MF20010103 - nitrate
OISO6: 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 0.994 (+/-0.52).
4 cross overs show no significant differences (<2%), and 3 of them involve
cruises that are thought to have no offset in nitrate. When the suggested
offsets for the other cruises are taken into account as well as the suggested
natural variability at 56°S, the average of all cross overs is 1.004 (+/-0.005).
This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 1.015 (+/-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 1.049 (+/-0.013),
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 (1.013).
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for nitrate.

anything Clair suggested for them.

35MF20010103 - silicate
OISO6: 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 1.025
(+/-0.046).
Only 2 cross overs found at 30°S show no significant differences (<2%) but they
involve cruises that are thought to have high silicate. When the suggested
offsets are taken into account the average of the 5 cross overs found at 30°S is
1.024 (+/-0.007). This suggests that a small adjustment could be required
(0.98).
At 56°S, however, when the suggested offsets as well as the suggested natural
variability are taken into account the average of the 6 cross overs is 1.001
(+/-0.003). This suggests that no adjustment would be required, but it is not
warranted since Antarctic deep waters are entitled to natural variability which
could mask the offset observed at 30°S.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 1.031 (+/-0.019),
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 0.938 (+/-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 (1.008).
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 0.98 for silicate.

35MF20010103 - oxygen
OISO6: only one deep profiles (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 1.007 (+/-0.029).
3 cross overs show no significant differences (<1%) and 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 0.996
(+/-0.004). This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO3 shows a ratio of 1.006 (+/-0.006), which
supports the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for oxygen.

35MF20010103 - silicate
OISO6: 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 1.025
(+/-0.046).
Only 2 cross overs found at 30°S show no significant differences (<2%) but they
involve cruises that are thought to have high silicate. When the suggested
offsets are taken into account the average of the 5 cross overs found at 30°S is
1.024 (+/-0.007). This suggests that a small adjustment could be required
(0.98).
At 56°S, however, when the suggested offsets as well as the suggested natural
variability are taken into account the average of the 6 cross overs is 1.001
(+/-0.003). This suggests that no adjustment would be required, but it is not
warranted since Antarctic deep waters are entitled to natural variability which
could mask the offset observed at 30°S.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 1.031 (+/-0.019),
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 0.938 (+/-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 (1.008).
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 0.98 for silicate.

35MF20010103 - nitrate
OISO6: 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 0.994 (+/-0.52).
4 cross overs show no significant differences (<2%), and 3 of them involve
cruises that are thought to have no offset in nitrate. When the suggested
offsets for the other cruises are taken into account as well as the suggested
natural variability at 56°S, the average of all cross overs is 1.004 (+/-0.005).
This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 1.015 (+/-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 1.049 (+/-0.013),
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 (1.013).
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for nitrate.

35MF20010103 - alkalinity
OISO6: 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 -2.0 (+/-3.7)
umol/kg.
All cross overs but 2 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 (-3.0
+/-2.8 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 is reduced (-2.8 +/-1.2 umol/kg).
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show differences
of -17.0 (+/-1.3) umol/kg and -14.7 (+/-3.0) 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 14 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.

35MF20010103 - tco2
OISO6: 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 +1.4 (+/-3.9)
umol/kg.
7 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 +0.3
(+/-3.1) umol/kg. This suggests that no adjustment would be required.
It should be noted, however, that larger offsets are found at 30°S (+2.9 +/-1.3
umol/kg), compared to 56°S (-1.8 +/-2.3 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 offsets of
-8.4 (+/-4.6) umol/kg and -5.1 (+/-2.0) 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. This supports no adjustment.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for TCO2.

35MF20010103 - salinity
OISO6: 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 +6.1 (+/-9.0)
ppm.
9 cross overs show significant differences (>5 ppm) and involve cruises that are
thought to have no significant offset in salinity. When the offsets suggested
for the other cruises are taken into account the average of all cross overs is
+7.6 (+/-2.5) ppm. It should be noted, however, that lower offsets are found at
56°S (mean of +6 +/-1 ppm) compared to 30°S (mean of +10 +/-1 ppm).
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of
+10 (+/-9) ppm and +3 (+/-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 an adjustment of -10 ppm for salinity.
