33RO19980123: Copied comments from duplicate entryPosted on 2014-06-19 15:16:50 - last updated on 2014-06-19 15:16:50 as version number 0
The following comments are copied 2014-JUN-19 from 31RB19980124 by Steven van Heuven. 31RB19980124 was a duplicate entry for 33RO19980123. After copying these comments here, cruise 31RB19980124 will be deleted from the GEOMAR table. All existing adjustments for 33RO19980123 are maintained (the only difference being that oxygen is 0.98 for 31RB19980124 and 0.99 for 33RO19980123). I've transferred a single figure here, too.

31RB19980124 - phosphate - (current GLODAPv2/GLODAPv1.2 comment)
New inversion for phosphate in the Atlantic with 10 core cruises assigned
confirms that NO adjustment should be applied.

The inversion suggest a correction of 0.9815, aka 0.98. This is based on 8
crossovers with a mean offset of 1.021. Without doubt these data are high.
Adjust by 0.98.

Bulk update requested by Anton Velo on 2015-06-04 including comments with
reasoning (src: ph_adjustments_g2_sent_carsten_20150604.xlsx / 2015-06-04): Make
0 by carbon interconsitency checks. Adjustment could be of about 0.005 pH units
for deepest data, but not more than 0.003 overally. Not applied as it's below
limit.

Autogenerated CTD salinity and CTD oxygen update - (current GLODAPv2/CARBOOCEAN comment)
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.

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.013, suggestin that the silicate is OK.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are not consistent with an upward
adjustment.
Based on these evidence, I suggest no adjustment for 33RO19980123 silicate.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.007, suggestin that the phosphate is OK.
The inversions suggest a small upward adjustment of 1.02.
However, the cross over results vs. other core-cruises are not consistent with
an upward adjustment.
Based on these evidence, I suggest no adjustment for 33RO19980123 phosphate.

Posted by ttanhua@geomar.de on 2008-06-12 11:38:29 UTC - Edit - Delete
This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The N/P ratio is 14.50, intercept 0.83.
The average of all cross overs is 0.984, suggestin that the nitrate values might
be a bit low.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are mostly consistent with an
upward adjustment,
but the results are inconclusive.
Most importantly, the two repeats of the A05 section 29HE19920714 and
74DI20040404 are both consistent
with an upward adjustment of 33RO19980123 nitrate values.
Based on these evidence, I suggest an upward adjustment of 1.02 for 33RO19980123
nitrate,
in line with the average offset of all cross overs.

The average of all cross overs is 1.017, suggesting that the oxygen values is a
bit higher.
The inversion suggests an adjustment of 0.987 WDLSQ and 0.984 WLSQ that is right
on the threshold of 1%.
The cross overs with other core-cruises are consistent with a downward
adjustment.
Based on these evidence, I suggest a downward adjustment of 0.99 for oxygen
values.

The average of all cross overs (manual) is 0.49.
The average of all cross overs (automatic) is 0.52.
Crossovers with core cruises only suggests offsets of 0.49(manual) and
-0.05(automatic)
The inversion suggests an upwards adjustment (4.36 and 3.35 for WLSQ and WDLSQ,
respectively).
There is a disconnect between the crossovers and the inversion.
Crossover recomendations all lie within the minimum cut-off limit.
The cross-overs with the core-cruises support no action.
This cruise is itself defined as a core cruise - the crossover results support
this.
Based on this I don't suggest any adjustment for the 33RO19980123 tco2 values.

Bulk update requested by Anton Velo on 2015-06-04 including comments with
reasoning (src: ph_adjustments_g2_sent_carsten_20150604.xlsx / 2015-06-04): Make
0 by carbon interconsitency checks. Adjustment could be of about 0.005 pH units
for deepest data, but not more than 0.003 overally. Not applied as it's below
limit.

Autogenerated CTD salinity and CTD oxygen update - (current GLODAPv2/CARBOOCEAN comment)
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.

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.013, suggestin that the silicate is OK.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are not consistent with an upward
adjustment.
Based on these evidence, I suggest no adjustment for 33RO19980123 silicate.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The N/P ratio is 14.50, intercept 0.83.
The average of all cross overs is 0.984, suggestin that the nitrate values might
be a bit low.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are mostly consistent with an
upward adjustment,
but the results are inconclusive.
Most importantly, the two repeats of the A05 section 29HE19920714 and
74DI20040404 are both consistent
with an upward adjustment of 33RO19980123 nitrate values.
Based on these evidence, I suggest an upward adjustment of 1.02 for 33RO19980123
nitrate,
in line with the average offset of all cross overs.

The average of all cross overs is 1.017, suggesting that the oxygen values is a
bit higher.
The inversion suggests an adjustment of 0.987 WDLSQ and 0.984 WLSQ that is right
on the threshold of 1%.
The cross overs with other core-cruises are consistent with a downward
adjustment.
Based on these evidence, I suggest a downward adjustment of 0.99 for oxygen
values.

The average of all cross overs (manual) is 0.49.
The average of all cross overs (automatic) is 0.52.
Crossovers with core cruises only suggests offsets of 0.49(manual) and
-0.05(automatic)
The inversion suggests an upwards adjustment (4.36 and 3.35 for WLSQ and WDLSQ,
respectively).
There is a disconnect between the crossovers and the inversion.
Crossover recomendations all lie within the minimum cut-off limit.
The cross-overs with the core-cruises support no action.
This cruise is itself defined as a core cruise - the crossover results support
this.
Based on this I don't suggest any adjustment for the 33RO19980123 tco2 values.

Automated update! This overwrites adjustment values (and flags) of CTDoxy and
CTDsal with the values from BOTsal and BOToxy for every cruise, unless CTDsal

Based on these evidence, I suggest no adjustment for 33RO19980123 phosphate.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The N/P ratio is 14.50, intercept 0.83.
The average of all cross overs is 0.984, suggestin that the nitrate values might
be a bit low.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are mostly consistent with an
upward adjustment,
but the results are inconclusive.
Most importantly, the two repeats of the A05 section 29HE19920714 and
74DI20040404 are both consistent
with an upward adjustment of 33RO19980123 nitrate values.
Based on these evidence, I suggest an upward adjustment of 1.02 for 33RO19980123
nitrate,
in line with the average offset of all cross overs.

There are 10 xovers. The fitted offset is -2.2. The suggested adjustment is 0
All inversion residuals are very close to 0 and fits inside +-3, except for 2
no-core cruises.
Very good fit with 6 GLODAP and 1 core cruises.

The average of all cross overs is 1.017, suggesting that the oxygen values is a
bit higher.
The inversion suggests an adjustment of 0.987 WDLSQ and 0.984 WLSQ that is right
on the threshold of 1%.
The cross overs with other core-cruises are consistent with a downward
adjustment.
Based on these evidence, I suggest a downward adjustment of 0.99 for oxygen
values.

33RO19980123 - tco2 - (current GLODAPv2/CARBOOCEAN comment)
The average of all cross overs (manual) is 0.49.
The average of all cross overs (automatic) is 0.52.
Crossovers with core cruises only suggests offsets of 0.49(manual) and
-0.05(automatic)
The inversion suggests an upwards adjustment (4.36 and 3.35 for WLSQ and WDLSQ,
respectively).
There is a disconnect between the crossovers and the inversion.
Crossover recomendations all lie within the minimum cut-off limit.
The cross-overs with the core-cruises support no action.
This cruise is itself defined as a core cruise - the crossover results support
this.
Based on this I don't suggest any adjustment for the 33RO19980123 tco2 values.

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

Bulk update requested by Anton Velo on 2015-06-04 including comments with
reasoning (src: ph_adjustments_g2_sent_carsten_20150604.xlsx / 2015-06-04): Make
0 by carbon interconsitency checks. Adjustment could be of about 0.005 pH units
for deepest data, but not more than 0.003 overally. Not applied as it's below
limit.

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.

Bulk update requested by Anton Velo on 2015-06-04 including comments with
reasoning (src: ph_adjustments_g2_sent_carsten_20150604.xlsx / 2015-06-04): Make
0 by carbon interconsitency checks. Adjustment could be of about 0.005 pH units
for deepest data, but not more than 0.003 overally. Not applied as it's below
limit.

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

Mean offset with 6 cruises: -0.5 which is clearly not significant. Therefore, NO

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.013, suggestin that the silicate is OK.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are not consistent with an upward
adjustment.
Based on these evidence, I suggest no adjustment for 33RO19980123 silicate.

33RO19980123 - phosphate - (current GLODAPv2/CARBOOCEAN comment)
This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.007, suggestin that the phosphate is OK.
The inversions suggest a small upward adjustment of 1.02.
However, the cross over results vs. other core-cruises are not consistent with
an upward adjustment.
Based on these evidence, I suggest no adjustment for 33RO19980123 phosphate.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The N/P ratio is 14.50, intercept 0.83.
The average of all cross overs is 0.984, suggestin that the nitrate values might
be a bit low.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are mostly consistent with an
upward adjustment,
but the results are inconclusive.
Most importantly, the two repeats of the A05 section 29HE19920714 and
74DI20040404 are both consistent
with an upward adjustment of 33RO19980123 nitrate values.
Based on these evidence, I suggest an upward adjustment of 1.02 for 33RO19980123
nitrate,
in line with the average offset of all cross overs.

The average of all cross overs is 1.017, suggesting that the oxygen values is a
bit higher.
The inversion suggests an adjustment of 0.987 WDLSQ and 0.984 WLSQ that is right
on the threshold of 1%.
The cross overs with other core-cruises are consistent with a downward
adjustment.
Based on these evidence, I suggest a downward adjustment of 0.99 for oxygen
values.

The average of all cross overs (manual) is 0.49.
The average of all cross overs (automatic) is 0.52.
Crossovers with core cruises only suggests offsets of 0.49(manual) and
-0.05(automatic)
The inversion suggests an upwards adjustment (4.36 and 3.35 for WLSQ and WDLSQ,
respectively).
There is a disconnect between the crossovers and the inversion.
Crossover recomendations all lie within the minimum cut-off limit.
The cross-overs with the core-cruises support no action.
This cruise is itself defined as a core cruise - the crossover results support
this.
Based on this I don't suggest any adjustment for the 33RO19980123 tco2 values.

33RO19980123 - silicate - (current GLODAPv2/CARBOOCEAN comment)
This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.013, suggestin that the silicate is OK.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are not consistent with an upward
adjustment.
Based on these evidence, I suggest no adjustment for 33RO19980123 silicate.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.007, suggestin that the phosphate is OK.
The inversions suggest a small upward adjustment of 1.02.
However, the cross over results vs. other core-cruises are not consistent with
an upward adjustment.
Based on these evidence, I suggest no adjustment for 33RO19980123 phosphate.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The N/P ratio is 14.50, intercept 0.83.
The average of all cross overs is 0.984, suggestin that the nitrate values might
be a bit low.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are mostly consistent with an
upward adjustment,
but the results are inconclusive.
Most importantly, the two repeats of the A05 section 29HE19920714 and
74DI20040404 are both consistent
with an upward adjustment of 33RO19980123 nitrate values.
Based on these evidence, I suggest an upward adjustment of 1.02 for 33RO19980123
nitrate,
in line with the average offset of all cross overs.

There are 10 xovers. The fitted offset is -2.2. The suggested adjustment is 0
All inversion residuals are very close to 0 and fits inside +-3, except for 2
no-core cruises.
Very good fit with 6 GLODAP and 1 core cruises.

The average of all cross overs is 1.017, suggesting that the oxygen values is a
bit higher.
The inversion suggests an adjustment of 0.987 WDLSQ and 0.984 WLSQ that is right
on the threshold of 1%.
The cross overs with other core-cruises are consistent with a downward
adjustment.
Based on these evidence, I suggest a downward adjustment of 0.99 for oxygen
values.

The average of all cross overs (manual) is 0.49.
The average of all cross overs (automatic) is 0.52.
Crossovers with core cruises only suggests offsets of 0.49(manual) and
-0.05(automatic)
The inversion suggests an upwards adjustment (4.36 and 3.35 for WLSQ and WDLSQ,
respectively).
There is a disconnect between the crossovers and the inversion.
Crossover recomendations all lie within the minimum cut-off limit.
The cross-overs with the core-cruises support no action.
This cruise is itself defined as a core cruise - the crossover results support
this.
Based on this I don't suggest any adjustment for the 33RO19980123 tco2 values.

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

Crossovers with core cruises only suggests offsets of 0.49(manual) and

There is a disconnect between the crossovers and the inversion.
Crossover recomendations all lie within the minimum cut-off limit.

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.013, suggestin that the silicate is OK.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are not consistent with an upward

The average of all cross overs (automatic) is 0.52.
Crossovers with core cruises only suggests offsets of 0.49(manual) and
-0.05(automatic)
The inversion suggests an upwards adjustment (4.36 and 3.35 for WLSQ and WDLSQ,

There is a disconnect between the crossovers and the inversion.
Crossover recomendations all lie within the minimum cut-off limit.

This cruise was included in GLODAP, but nutrients were not included in the
secondary QC for GLODAP.
Nitrate: The average of all crossovers is 0.98 and the inversion suggests no
adjustment.
The crossovers with the core-cruises are mostly consistent with an upward
adjustment,
but the results are inconclusive. Based on these evidences no adjustment was
applied to the nitrate values.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.013, suggestin that the silicate is OK.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are not consistent with an upward
adjustment.
Based on these evidence, I suggest no adjustment for 33RO19980123 silicate.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The average of all cross overs is 1.007, suggestin that the phosphate is OK.
The inversions suggest a small upward adjustment of 1.02.
However, the cross over results vs. other core-cruises are not consistent with

Based on these evidence, I suggest no adjustment for 33RO19980123 phosphate.

This is a GLODAP cruise, but was not included in the 2nd level QC (for GLODAP).
The N/P ratio is 14.50, intercept 0.83.
The average of all cross overs is 0.984, suggestin that the nitrate values might
be a bit low.
The inversions suggest no adjustment.
The cross over results vs. other core-cruises are mostly consistent with an
upward adjustment,
but the results are inconclusive.
Most importantly, the two repeats of the A05 section 29HE19920714 and
74DI20040404 are both consistent
with an upward adjustment of 33RO19980123 nitrate values.
Based on these evidence, I suggest an upward adjustment of 1.02 for 33RO19980123
nitrate,
in line with the average offset of all cross overs.

The average of all cross overs is 1.017, suggesting that the oxygen values is a
bit higher.
The inversion suggests an adjustment of 0.987 WDLSQ and 0.984 WLSQ that is right
on the threshold of 1%.
The cross overs with other core-cruises are consistent with a downward

Based on these evidence, I suggest a downward adjustment of 0.99 for oxygen

The average of all cross overs (manual) is 0.49.
The average of all cross overs (automatic) is 0.52.
Crossovers with core cruises only suggests offsets of 0.49(manual) and
-0.05(automatic)
The inversion suggests an upwards adjustment (4.36 and 3.35 for WLSQ and WDLSQ,
respectively).
There is a disconnect between the crossovers and the inversion.
Crossover recomendations all lie within the minimum cut-off limit.
The cross-overs with the core-cruises support no action.
This cruise is itself defined as a core cruise - the crossover results support
this.
Based on this I don't suggest any adjustment for the 33RO19980123 tco2 values.

Autogenerated CTD salinity and CTD oxygen update - (current GLODAPv2/CARBOOCEAN comment)
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.
