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.

35MF20000719 - oxygen

OISO5: only one deep profiles (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 1.013 (+/-0.029).
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 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 1.005 (+/-0.004), which
supports the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for oxygen.

35MF20000719 - silicate

OISO5: 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 1.061
(+/-0.039).
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 1.041 (+/-0.006). This suggests that an adjustment of 0.96 could be
required.
The cross overs found at 56°S show very similar results: The 1 reliable cross
over which involves a cruise that is thought to have no offset in silicate
suggests an offset of 1.042 (+/-0.006). 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 1.042 (+/-0.004).
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows an ratio of 1.045
(+/-0.014), which is in good agreement with the analysis above (note however
that INDIGO1 is thought to have slightly low silicate).
The cross over with the cruise INDIGO3 (56°S) shows a ratio of 0.974 (+/-0.010),
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 (1.048).
CONCLUSION:
All cross overs found at 30°S and 56°S agree to suggest an offset of 1.04.
Based on this I suggest an adjustment of 0.96 for silicate.

35MF20000719 - nitrate

OISO5: 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 0.947
(+/-0.043).
The 4 cross overs found at 30°S show significant differences (>2%) and all but 1
involve cruises that are thought to have no offset in nitrate. When the offset
suggested for the other cruise is taken into account the average of the 4 cross
overs found at 30°S is 0.940 (+/-0.006). This suggests that an adjustment of
1.06 could be required.
But the 6 cross overs found at 56°S suggest a lower adjustment : 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 0.983 (+/-0.003).
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 0.951 (+/-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 1.020 (+/-0.020),
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 (0.986).
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. Based on this I suggest an adjustment of 1.06 for
nitrate.

35MF20000719 - alkalinity

OISO5: 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 (+/-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 (-0.2
+/3.3 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 (-0.4 +/-1.7 umol/kg).
OTHER CROSS OVERS:
The cross overs with cruises INDIGO1 (30°S) and INDIGO3 (56°S) show differences
of -19.8 (+/-1.3) umol/kg and -14.4 (+/-3.6) 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 13.5 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.

35MF20000719 - tco2

OISO5: 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 +0.3 (+/-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 -0.8
(+/-1.4) umol/kg. This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross overs with INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of -11.1
(+/-2.5) umol/kg and -6.3 (+/-2.3) 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.

35MF20000719 - salinity

OISO5: 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 -3.6 (+/-9.3)
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 -0.5 (+/-2.3) ppm. This suggests that no adjustment would be required.
OTHER CROSS OVERS:
The cross overs with INDIGO1 (30°S) and INDIGO3 (56°S) show offsets of -2
(+/-10) ppm and -4 (+/-4) ppm, respectively, which supports no adjustment.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for salinity.

35MF20000719 - nitrate

OISO5: 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 0.947
(+/-0.043).
The 4 cross overs found at 30°S show significant differences (>2%) and all but 1
involve cruises that are thought to have no offset in nitrate. When the offset
suggested for the other cruise is taken into account the average of the 4 cross
overs found at 30°S is 0.940 (+/-0.006). This suggests that an adjustment of
1.06 could be required.
But the 6 cross overs found at 56°S suggest a lower adjustment : 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 0.983 (+/-0.003).
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows a ratio of 0.951 (+/-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 1.020 (+/-0.020),
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 (0.986).
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. Based on this I suggest an adjustment of 1.06 for
nitrate.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2 Adjustment IND and PAC_SvH_20140611.xlsx): : maintain. I cannot solve
these 35MF cruises for Silicate, and by this stage will happily just accept
anything Clair suggested for them.

35MF20000719 - silicate

OISO5: 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 1.061
(+/-0.039).
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 1.041 (+/-0.006). This suggests that an adjustment of 0.96 could be
required.
The cross overs found at 56°S show very similar results: The 1 reliable cross
over which involves a cruise that is thought to have no offset in silicate
suggests an offset of 1.042 (+/-0.006). 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 1.042 (+/-0.004).
OTHER CROSS OVERS:
The cross over with the cruise INDIGO1 (30°S) shows an ratio of 1.045
(+/-0.014), which is in good agreement with the analysis above (note however
that INDIGO1 is thought to have slightly low silicate).
The cross over with the cruise INDIGO3 (56°S) shows a ratio of 0.974 (+/-0.010),
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 (1.048).
CONCLUSION:
All cross overs found at 30°S and 56°S agree to suggest an offset of 1.04.
Based on this I suggest an adjustment of 0.96 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.

Autogenerated comment - oxygen

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2 Adjustment IND and PAC_SvH_20140611.xlsx): : make 1.01. This is average
of offsets, and suggestion of inverions, and makes sense upon inspection.

35MF20000719 - oxygen

OISO5: only one deep profiles (at 56°S).
INTERNAL OISO CONSISTENCY:
6 cross overs were analyzed. The average of all cross overs is 1.013 (+/-0.029).
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 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 1.005 (+/-0.004), which
supports the analysis above.
CONCLUSION:
Based on the regional analyses above I suggest no adjustment for oxygen.
