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

CARINA (Velo et al. 2009 ESSD) suggests: -8

323019940104 - tco2

Mean offset with 12 cruises: -1.1
Inversion suggests: -2.0
I suggest NO adjustment, in agreement with GLODAPv1 and CARINA (Pierrot et al,
ESSD, 2010)

Posted by mario.hoppema@awi.de on 2012-12-10 15:30:06 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

323019940104 - phosphate

Earlier decision of giving no adjustment is confirmed by new inversion for
phosphate in the Atlantic with 10 core cruises assigned.

Posted by mario.hoppema@awi.de on 2012-11-23 15:22:55 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

323019940104 - oxygen

The inversion suggest a correction of 0.9995 based on 23 crossovers with a mean
offset of 0.998, no adjustment is recommended.

Posted by are.olsen@uib.no on 2012-09-24 10:12:38 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

323019940104 - silicate

The inversion suggest a correction of 0.9827 and the mean offset is 1.017, and
the data do look a bit high, (there are also 23 valid crossovers from the
southwest atlantic, where this cruise took place). I believe this and recommend
that an adjustment of 0.98 is applied to these data. A high bias of 1.6 was
determined in GLODAP and the x0.98 adjustment is consistent with the adjustment
recommended in CARINA.

323019940104 - phosphate

Suggested correction is 1.0252 but mean offset is 0.997. No adjustment is
recommended. Consistent with CARINA.

323019940104 - nitrate

Suggested correction is 0.9865 and MO 1.017. Do not adjust. Consistent with
CARINA.

323019940104 - salinity

The inversion suggest a correction of -0.61 ppm, based on ~23 crossovers with a
mean offset of 2.8 ppm. Do not adjust. This is consistent with CARINA.

323019940104 - silicate

UPDATE
A new inversion analysis for the Southern Ocean data has been done (13 Oct.
2008), now with data to which all suggested adjustments from the first round
were applied. This new analysis suggests a significant adjustment of 0.976
-
Both initial inversion analyses for the North Atlantic and Southern Ocean data
sets did suggests a significant adjustment, but we decided not to follow it (see
other comments). However, after the new inversion analysis, an adjustment is
still suggested.
We therefore suggest a small adjustment of silicate by 0.98

323019940104 - silicate

By comparing the cross overs from the core cruises to this cruise, I find it
dificult to motivate an adjustment of the values.
I would suggest that no adjustment is applied

323019940104 - nitrate

This cruise is in GLODAP. The analysis by Gouretski and Jancke (PiO, 2001)
sugggest an adjustment of 0.06 umol/kg.
The N/P ratio is 15.27, intercept -0.79.
The average of all cross overs is 1.002
The inversion suggest an adjustment of 0.96 and 0.98 for WLSQ and WDLSQ,
respectively.
The cross-overs with the core cruises are inconclusive, but largely supports no
adjustment.

Average offsets:
2.40 (automatic)

Average offsets from xovers with Core Cruises:
1.35 (automatic)
1.35 (manual)
Inversion Results:
-1.57 WLSQ
-2.04 WDLSQ
Comments: All xovers with core cruises show low offsets. 2 xovers with 56 and
1084 show large offsets which go close to zero after adjustments suggested for
these 2 cruises.
Therefore I suggests no adjustment

Suggested adjustment: 0
quality: good

There are 8 xovers. The fitted offset is -8.9. The suggested adjustment is -8

323019940104 - silicate

Average of all cross-overs is 0.990 (Southern Ocean) and 1.000 (North Atlantic).
Inversion analysis suggests an adjustment of 0.976 (Southern Ocean) and 0.967
(North Atlantic).
The results are inconclusive. I notice that the mean cross-overs results are
strongly influenced by two cruises (29HE20010305, 29HE20020304) with low
cross-overs (and large standard deviations). Cross-over with core cruise
49NZ20031106 does not warrant an adjustment.
At the Paris meeting we agreed on NO adjustment of silicate of cruise
323019940104.

Average of all cross-overs is 1.007 (Southern Ocean) and 1.001 (North Atlantic).
Inversion analysis suggests no significant adjustment for either of the two

Cross-overs with core cruises do not support an adjustment.
I suggest NO adjustment of phosphate for cruise 323019940104.

323019940104 - nitrate

Average of all cross-overs is: 1.002
Inversion analysis (Southern Ocean) suggests no significant adjustment (0.993);
on the other hand, inversion analysis for the North Atlantic does suggest a
slight adjustment of 0.977
Cross-overs with core cruises (49NZ20031106, 74JC19950320, SAVE) do not support
an adjustment - those with 29HE20020304 show a very large standard deviation,
and thus is not significant.
Based on all this I suggest NO adjustment of nitrate for cruise 323019940104.

The average of all cross overs is 0.997.

an offset for alkalinity of -8 was stated.
There are 8 xovers. The fitted offset is -8.9. The suggested adjustment is -8
because it agrees with -8.9+-0.8 of the fitting.
Most of inversion residuals fits inside +-5.
Very good fit with 4 GLODAP.

keep at 1.00

Earlier decision of giving no adjustment is confirmed by new inversion for
phosphate in the Atlantic with 10 core cruises assigned.

Suggested correction is 1.0252 but mean offset is 0.997. No adjustment is
recommended. Consistent with CARINA.

323019940104 - phosphate

Average of all cross-overs is 1.007 (Southern Ocean) and 1.001 (North Atlantic).
Inversion analysis suggests no significant adjustment for either of the two
regions.
Cross-overs with core cruises do not support an adjustment.
I suggest NO adjustment of phosphate for cruise 323019940104.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : maintain 0.98

Posted by svheuven@gmail.com on 2015-01-08 16:40:55 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

323019940104 - silicate

The inversion suggest a correction of 0.9827 and the mean offset is 1.017, and
the data do look a bit high, (there are also 23 valid crossovers from the
southwest atlantic, where this cruise took place). I believe this and recommend
that an adjustment of 0.98 is applied to these data. A high bias of 1.6 was
determined in GLODAP and the x0.98 adjustment is consistent with the adjustment
recommended in CARINA.

323019940104 - silicate

UPDATE
A new inversion analysis for the Southern Ocean data has been done (13 Oct.
2008), now with data to which all suggested adjustments from the first round
were applied. This new analysis suggests a significant adjustment of 0.976
-
Both initial inversion analyses for the North Atlantic and Southern Ocean data
sets did suggests a significant adjustment, but we decided not to follow it (see
other comments). However, after the new inversion analysis, an adjustment is
still suggested.
We therefore suggest a small adjustment of silicate by 0.98

323019940104 - silicate

By comparing the cross overs from the core cruises to this cruise, I find it
dificult to motivate an adjustment of the values.
I would suggest that no adjustment is applied

Posted by ttanhua@geomar.de on 2008-06-12 11:29:07 UTC for data product: CARINA

323019940104 - silicate

Average of all cross-overs is 0.990 (Southern Ocean) and 1.000 (North Atlantic).
Inversion analysis suggests an adjustment of 0.976 (Southern Ocean) and 0.967
(North Atlantic).
The results are inconclusive. I notice that the mean cross-overs results are
strongly influenced by two cruises (29HE20010305, 29HE20020304) with low
cross-overs (and large standard deviations). Cross-over with core cruise
49NZ20031106 does not warrant an adjustment.
At the Paris meeting we agreed on NO adjustment of silicate of cruise
323019940104.

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

The average of all cross overs is 0.997.

The cross-overs with other core cruises do not support that an adjustment is

Based on this I suggest no adjustment to the oxygen values.
