35MF20000117 - salinity
OISO4: 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 -4.0 (+/-9.2)
ppm.
7 cross overs show no 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 -0.9 (+/-1.9) ppm. This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of
-3 (+/-9) ppm and -4 (+/-2) ppm, respectively, which supports no adjustment.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for salinity.

35MF20000117 - tco2
OISO4: 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 +1.6 (+/-3.5)
umol/kg.
8 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
(+/-1.6) umol/kg. This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of
-9.7 (+/-5.5) umol/kg and -4.4 (+/-3.9) 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.

35MF20000117 - nitrate
OISO4: 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 1.023 (+/-0.50).
All cross overs but 1 show significant differences (>2%). When the suggested
offsets are taken into account as well as the suggested natural variability at
56°S, the average of all cross overs is 1.028 (+/-0.008). Note that cross overs
found at 30°S show a slightly larger average (1.032 +/-0.007) than those found
at 56°S (1.025 +/-0.008). This suggests that an adjustment of 0.97 could be
required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 1.047 (+/-0.013)
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 1.062 (+/-0.016),
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 (1.026).
CONCLUSION:
Based on the regional analyses above I suggest an adjustment of 0.97 for
nitrate.

anything Clair suggested for them.

35MF20000117 - silicate
OISO4: 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 0.980
(+/-0.055).
Only one cross overs found at 30°S show no significant differences (<2%) but it
involves a cruise that is thought to have slightly high silicate. When the
suggested offsets are taken into account the average of the 5 cross overs found
at 30°S is 1.012 (+/-0.002). This suggests that no adjustment would be required.
At 56°S, however, 1 reliable cross over which involves a cruise that is thought
to have no offset in silicate suggests an offset of 1.065 (+/-0.023). When the
offsets suggested for the other cruises as well as the suggested natural
variability are taken into account the average of the 6 cross overs found at
56°S is 0.942 (+/-0.004). This suggests that an adjustment of 1.06 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 1.038 (+/-0.038),
which is in relatively 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 0.878 (+/-0.024),
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 (0.944).
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 silicate.

OISO4: only one deep profiles (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 0.937 (+/-0.008).
All cross overs show significant differences ranging from 0.93 to 0.95 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 0.937 (+/-0.003). This suggests that an adjustment of 1.06

CONCLUSION:
Based on the regional analyses above I suggest an adjustment of 1.06 for oxygen.

35MF20000117 - oxygen
OISO4: only one deep profiles (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 0.937 (+/-0.008).
All cross overs show significant differences ranging from 0.93 to 0.95 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 0.937 (+/-0.003). This suggests that an adjustment of 1.06
could be required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO3 shows a ratio of 0.944 (+/-0.006), which
supports the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest an adjustment of 1.06 for oxygen.

offsets suggested for the other cruises as well as the suggested natural
variability are taken into account the average of the 6 cross overs found at
56°S is 0.942 (+/-0.004). This suggests that an adjustment of 1.06 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 1.038 (+/-0.038),
which is in relatively 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 0.878 (+/-0.024),
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 (0.944).
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 silicate.

35MF20000117 - nitrate
OISO4: 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 1.023 (+/-0.50).
All cross overs but 1 show significant differences (>2%). When the suggested
offsets are taken into account as well as the suggested natural variability at
56°S, the average of all cross overs is 1.028 (+/-0.008). Note that cross overs
found at 30°S show a slightly larger average (1.032 +/-0.007) than those found
at 56°S (1.025 +/-0.008). This suggests that an adjustment of 0.97 could be
required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 1.047 (+/-0.013)
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 1.062 (+/-0.016),
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 (1.026).
CONCLUSION:
Based on the regional analyses above I suggest an adjustment of 0.97 for
nitrate.

35MF20000117 - tco2
OISO4: 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 +1.6 (+/-3.5)
umol/kg.
8 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
(+/-1.6) umol/kg. This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of
-9.7 (+/-5.5) umol/kg and -4.4 (+/-3.9) 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.

35MF20000117 - salinity
OISO4: 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 -4.0 (+/-9.2)
ppm.
7 cross overs show no 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 -0.9 (+/-1.9) ppm. This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of
-3 (+/-9) ppm and -4 (+/-2) ppm, respectively, which supports no adjustment.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for salinity.
