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:3; no CTD oxygen data. Setting CTD oxygen offset to -999, QC
flag removed.

09AR19930404 - oxygen

1.03 perfectly improves fit in a two-step ('adjust severe biases first')
inversion of the full Southern Hemisphere and more local inversions.

Posted by svheuven@gmail.com on 2014-04-23 11:00:29 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19930404 - silicate

Recent inversions based on unadjusted data suggest that 09FA19930624 indeed ties
in perfectly with the Pacific data, suggesting that the full 6.5% offset between
that cruise and this one (09AR19930404) is due to bias in 09AR19930404.
Implementing the 1.065 improves local data consistency remarkably.

Posted by svheuven@gmail.com on 2014-04-23 10:57:44 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19930404 - nitrate

This cruise has two strongly outlying stations far south (no3>34; stations 60
and 61) that affect many of the xovers. These should be flagged in QC1. Close
inspection shows no clear overall offset of cruise. On the other hand, this
cruise is only 5% lower than 09FA19930624, which itself is almost certainly 9%
too high. That suggests 09AR19930404 is 4% too high itself. The GEOMAR table
currently has 0.96 (although the note says 'recommend no afjustment). Inversions
suggest 0.98 to 0.995, although to some extent biased by those outlying
stations. I recommend maintaining the existing adjustment of 0.96.

Posted by svheuven@gmail.com on 2014-04-23 10:53:23 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19930404 - salinity

Changed -0.007 back to -0.010, per Claire's suggestion. That -0.010 is is line
with what various large-scale inversions (e.g., full Southern Ocean) suggest
(-0.008 to -0.010). The existing -0.007 was undocumented.

Posted by svheuven@gmail.com on 2014-04-23 10:39:24 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19930404 - silicate

The crossover and inversion analysis carried out on the Beta version before the
Bremen workshop revealed that this cruise (which had been adjusted by 0.98 in
the Beta product), was biased low by 7-8% with respect to 09FA19930624. This was
the only xover generated as this was carried out on the Pacific product file and
is uploaded here (comment, from Beta inversion). The 09FA cruise ties in with
the rest of the Pacific and appears unbiased. At the Bremen workshop we decided
to change the 0.98 applied adjustment from Pacifica to 1.05. The xover and
inversion of the unadjusted data carried out later, confirmed that this decision
was correct.

09AR19930404 - oxygen

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is 0.953.
The global inversion (WDLSQ) suggests an adjustment of 1.037 (+/-0.026).
REGIONAL ANALYSIS:
5 cross overs were analyzed. The average of all cross overs is 0.951 (+/-0.016).
All cross overs show significant differences ranging from 0.94 to 0.98. Only 1
of them involve a cruise that is thought to have no significant offset in
oxygen. When the offsets suggested for the other cruises are taken into account,
the average of all cross overs is 0.969 (+/-0.007). This suggests that an
adjustment of 1.03 could be required.
CONCLUSION:
The global and regional analyses agree.
Based on this I suggest an adjustment of 1.03 for oxygen.

09AR19930404 - silicate

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is 0.969.
The global inversion (WDLSQ) suggests that an adjustment of 1.07 could be
required (1.066 +/-0.060).
REGIONAL ANALYSIS:
5 cross overs were analyzed, but 2 are discarded due to large uncertainty (with
cruises 09AR20011029 and 09AR19960822). The average of the 4 cross overs is
0.924 (+/-0.042).
All cross overs show significant differences ranging from 1.033 to 1.0.129 and
none of them involve cruises that are thought to have no significant offset in
silicate. When the suggested offsets are taken into account, the average of all
cross overs is 0.930 (+/-0.014). This suggests that an adjustment of 1.07 could
be required.
CONCLUSION:
The global and regional analyses agree.
Based on this I suggest an adjustment of 1.07 for silicate.

09AR19930404 - phosphate

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is 1.020.
The global inversion (WDLSQ) suggests that an adjustment of 0.96 could be
required (0.958 +/-0.053).
REGIONAL ANALYSIS:
5 cross overs were analyzed, but 1 is discarded due to large uncertainty (with
cruise 09AR20011029). The average of the 4 cross overs is 1.017 (+/-0.036).
3 cross overs show no significant differences (<2%), but only 1 of them involves
a cruise that is thought to have no significant offset in phosphate. When the
offsets suggested for the other cruises are taken into account, the average of
all cross overs is 1.020 (+/-0.005). This suggests that an adjustment of 0.98
could be required.
CONCLUSION:
The global and regional analyses suggest high phosphate values, but different
adjustments are proposed: 0.96 or 0.98, respectively. The latter suggestion is
preferred due to the large uncertainty attached to the result of the inversion.
Based on this I suggest an adjustment of 0.98 for phosphate.

09AR19930404 - nitrate

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is 1.011.
The global inversion (WDLSQ) suggests that an adjustment of 0.96 could be
required (0.958 +/-0.056).
REGIONAL ANALYSIS:
5 cross overs were analyzed, but 1 is discarded due to large uncertainty (with
cruise 09AR20011029). The average of the 4 considered cross overs is 0.986
(+/-0.034).
3 cross overs show no significant differences (<2%) and involve cruises that are
thought to have no significant offset in nitrate. When the offset suggested for
the other cruise is taken into account, the average of the 4 cross overs is
1.008 (+/-0.012). This suggests that no adjustment would be required.
CONCLUSION:
The global and regional analyses disagree. The former suggests that an
adjustment could be required, whereas the latter suggests no adjustment. The
latter result is preferred due to the large uncertainty attached to the result
of the inversion.
Based on this I suggest no adjustment for nitrate.

09AR19930404 - tco2

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is -1.5 umol/kg.
No suggestion from the global inversion.
REGIONAL ANALYSIS:
2 cross overs were analyzed. The average of all cross overs is -0.1 (+/-1.3)
umol/kg.
The 2 cross overs show no significant differences (<4 umol/kg) and involve
cruises that are thought to have no significant offset in TCO2. This suggests
that no adjustment would be required.
CONCLUSION:
Based on the regional analysis above I suggest no adjustment for TCO2.

09AR19930404 - salinity

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is +10.4 ppm.
The global inversion (WDLSQ) suggests that an adjustment could be required (-7.4
+/-6.7 ppm).
REGIONAL ANALYSIS:
5 cross overs were analyzed. The average of all cross overs is +10.2 (+/-2.2)
ppm.
All cross overs show significant differences (from +7 to +13 ppm) and involve
cruises that are thought to have no significant offsets in salinity. This
suggests that an adjustment of -10 ppm could be required.
CONCLUSION:
The global and regional analyses suggest high salinity values, but different
adjustments are proposed: -7 ppm or -10 ppm, respectively. The latter suggestion
is preferred due to the large uncertainty attached to the result of the
inversion.
Based on this I suggest an adjustment of -10 ppm for salinity.

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is 1.011.
The global inversion (WDLSQ) suggests that an adjustment of 0.96 could be
required (0.958 +/-0.056).
REGIONAL ANALYSIS:
5 cross overs were analyzed, but 1 is discarded due to large uncertainty (with
cruise 09AR20011029). The average of the 4 considered cross overs is 0.986
(+/-0.034).
3 cross overs show no significant differences (<2%) and involve cruises that are
thought to have no significant offset in nitrate. When the offset suggested for
the other cruise is taken into account, the average of the 4 cross overs is
1.008 (+/-0.012). This suggests that no adjustment would be required.
CONCLUSION:
The global and regional analyses disagree. The former suggests that an
adjustment could be required, whereas the latter suggests no adjustment. The
latter result is preferred due to the large uncertainty attached to the result
of the inversion.
Based on this I suggest no adjustment for nitrate.

Autogenerated comment - silicate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2 Adjustment IND and PAC_SvH_20140611.xlsx): : make 1.065, which is what
the SO20S inversion says.

Posted by svheuven@gmail.com on 2014-06-16 15:50:31 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19930404 - silicate

Recent inversions based on unadjusted data suggest that 09FA19930624 indeed ties
in perfectly with the Pacific data, suggesting that the full 6.5% offset between
that cruise and this one (09AR19930404) is due to bias in 09AR19930404.
Implementing the 1.065 improves local data consistency remarkably.

Posted by svheuven@gmail.com on 2014-04-23 10:57:44 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

09AR19930404 - silicate

The crossover and inversion analysis carried out on the Beta version before the
Bremen workshop revealed that this cruise (which had been adjusted by 0.98 in
the Beta product), was biased low by 7-8% with respect to 09FA19930624. This was
the only xover generated as this was carried out on the Pacific product file and
is uploaded here (comment, from Beta inversion). The 09FA cruise ties in with
the rest of the Pacific and appears unbiased. At the Bremen workshop we decided
to change the 0.98 applied adjustment from Pacifica to 1.05. The xover and
inversion of the unadjusted data carried out later, confirmed that this decision
was correct.

09AR19930404 - silicate

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is 0.969.
The global inversion (WDLSQ) suggests that an adjustment of 1.07 could be
required (1.066 +/-0.060).
REGIONAL ANALYSIS:
5 cross overs were analyzed, but 2 are discarded due to large uncertainty (with
cruises 09AR20011029 and 09AR19960822). The average of the 4 cross overs is
0.924 (+/-0.042).
All cross overs show significant differences ranging from 1.033 to 1.0.129 and
none of them involve cruises that are thought to have no significant offset in
silicate. When the suggested offsets are taken into account, the average of all
cross overs is 0.930 (+/-0.014). This suggests that an adjustment of 1.07 could
be required.
CONCLUSION:
The global and regional analyses agree.
Based on this I suggest an adjustment of 1.07 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:3; no CTD oxygen data. Setting CTD oxygen offset to -999, QC
flag removed.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2 Adjustment IND and PAC_SvH_20140611.xlsx): : make 1.03. This is the
results of various inversions, and improves the match very well.

09AR19930404 - oxygen

1.03 perfectly improves fit in a two-step ('adjust severe biases first')
inversion of the full Southern Hemisphere and more local inversions.

09AR19930404 - oxygen

GLOBAL ANALYSIS (Cruise plot file: RC_SO):
The average of all cross overs is 0.953.
The global inversion (WDLSQ) suggests an adjustment of 1.037 (+/-0.026).
REGIONAL ANALYSIS:
5 cross overs were analyzed. The average of all cross overs is 0.951 (+/-0.016).
All cross overs show significant differences ranging from 0.94 to 0.98. Only 1
of them involve a cruise that is thought to have no significant offset in
oxygen. When the offsets suggested for the other cruises are taken into account,
the average of all cross overs is 0.969 (+/-0.007). This suggests that an
adjustment of 1.03 could be required.
CONCLUSION:
The global and regional analyses agree.
Based on this I suggest an adjustment of 1.03 for oxygen.
