35MF20020104 - oxygen

OISO8: only one deep profiles (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 1.013 (+/-0.028).
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 1.002
(+/-0.003). This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO3 shows a ratio of 1.010 (+/-0.005), in
relatively good agreement with the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for oxygen.

35MF20020104 - silicate

OISO8: 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 0.952
(+/-0.039).
Only 2 cross overs found at 30°S show no significant differences (<2%) but they
involve cruises that are thought to have low silicate. When the suggested
offsets are taken into account the average of the 5 cross overs found at 30°S is
0.964 (+/-0.006). This suggests that an adjustment of 1.04 could 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 1.070 (+/-0.008). 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 is 0.938
(+/-0.002). This suggests that a large 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 0.979 (+/-0.009),
in good agreement with the analysis above (INDIGO1 is thought to have slightly
low silicate).
The cross over with the cruise INDIGO3 (56°S) shows a ratio of 0.877 (+/-0.009),
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 (0.943).
CONCLUSION:
The different results obtained at 30°S and 56°S are probably due to natural
changes that would have operated 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.

35MF20020104 - nitrate

OISO8: only one deep profile for nitrate (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 0.933 (+/-0.047).
All cross overs show significant differences ranging from 0.85 to 0.98. Only one
of them involves a cruise that is thought to have no offset in nitrate and
appears reliable (0.955 +/-0.005 with 35MF20010103). When the natural changes in
nitrate suggested for the other cruises are taken into account, the average of
all cross overs is 0.961 (+/-0.004). This suggests that an adjustment of 1.04
could be required, but it is not warranted since Antarctic deep waters are
entitled to natural variability, which could play a role in the observed
differences (all cross overs are found at 56°S).
OTHER CROSS OVERS:
The cross over with the cruise INDIGO3 shows a ratio of 0.997 (+/-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, it translates
into an offset of 0.963. This supports the analysis above.
CONCLUSION:
Given the large uncertainty attached to the regional analyses above due to
natural variability in the Antarctic region, I have no recommendation for
nitrate.

35MF20020104 - alkalinity

OISO8: 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 -2.6 (+/-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 (-2.5
+/-3.4 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 (-1.0 +/-1.6 umol/kg).
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show differences
of -17.9 (+/-1.4) umol/kg and -16.6 (+/-3.7) 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 15 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.

35MF20020104 - tco2

OISO8: 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 -6.6 (+/-2.2)
umol/kg.
Only 2 cross overs show no significant differences (<4 umol/kg), one of them
involving a cruise that is thought to have no offest in TCO2 values. The 9
others show offsets ranging from -4.5 to -9.4 umol/kg, which suggests that the
cruise would have low TCO2 values. When the suggested offsets are taken into
account the average of all cross overs is -6.5 (+/-1.9) umol/kg. This suggests
that an adjustment of +6.5 umol/kg could be required.
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of
-15.7 (+/-2.7) umol/kg and -13.3 (+/-1.8) umol/kg, repectively. 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 offsets of about -6 umol/kg and -7 umol/kg,
respectively. This supports the result of the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest an adjustment of +6.5 umol/kg for
TCO2.

35MF20020104 - salinity

OISO8: 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 -2.5 (+/-9.4)
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 +0.7 (+/-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
-1 (+/-7) ppm and -2(+/-2) ppm, respectively, which supports no adjustment.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for salinity.

35MF20020104 - silicate

OISO8: 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 0.952
(+/-0.039).
Only 2 cross overs found at 30°S show no significant differences (<2%) but they
involve cruises that are thought to have low silicate. When the suggested
offsets are taken into account the average of the 5 cross overs found at 30°S is
0.964 (+/-0.006). This suggests that an adjustment of 1.04 could 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 1.070 (+/-0.008). 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 is 0.938
(+/-0.002). This suggests that a large 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 0.979 (+/-0.009),
in good agreement with the analysis above (INDIGO1 is thought to have slightly
low silicate).
The cross over with the cruise INDIGO3 (56°S) shows a ratio of 0.877 (+/-0.009),
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 (0.943).
CONCLUSION:
The different results obtained at 30°S and 56°S are probably due to natural
changes that would have operated 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.

Autogenerated CTD salinity and CTD oxygen update

Automated update! This overwrites adjustment values (and flags) of CTDoxy and
CTDsal with the values from BOTsal and BOToxy for every cruise, unless CTDsal
(or CTDoxy) is not present or bad.
Salinity action ID:5; CTD salinity data good, setting CTD salinity offset and QC
flag to bottle values.
Oxygen action ID:5; CTD oxygen data good, setting CTD oxygen offset and QC flag
to bottle values.

35MF20020104 - oxygen

OISO8: only one deep profiles (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 1.013 (+/-0.028).
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 1.002
(+/-0.003). This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross over with the cruise INDIGO3 shows a ratio of 1.010 (+/-0.005), in
relatively good agreement with the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for oxygen.
