The selected Calculated Carbon Parameter has been dismissed in October 2017! Legacy values will be exported as is and displayed in red with subscript "c", e.g. -0.123456_c! No data available? Insert -999 No suggestion for adjustment possible? Insert -888 To calibrate CTDsal use: CTDsal_calibrated = (CTDsal - CTDsal_intercept) / CTDsal_slope To calibrate CTDoxy use: CTDoxy_calibrated = (CTDoxy - CTDoxy_intercept) / CTDoxy_slope

Autogenerated update by AV for pH

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. Xovers/Inversion of calculated TCO2 from TALK and pH suggest no adjustment.
Probably a bit low, but below limit.

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.

Autogenerated comment - oxygen

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : maintain 1.00. Not fully
inspected, but inversion says abs(adj)<0.5% and existing suggestion is also
<0.5%

Autogenerated comment - silicate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 1.02. That's the inversion
suggestion, and also the approximate bias against AQ2010, which is accurate.

Autogenerated comment - phosphate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 0.99. Fair profiles, no
evidence of drift (as opposed to NO3 for this cruise). Cruise is 1-2% high, will
correct down by 1%, in accordance with results of various inversions. Clear
offset of -1% against AJAX-1 (which is 2% too high) confirm this.

Autogenerated comment - nitrate

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make -777. Profiles show extreme
drift along the cruisetrack (or rather a break?). Comparing 35MF2008 and
90AV2004, it is clear that south of 42ºS (that is also west of 10ºW), 90AV is
7.5% lower than 35MF2008. On the NE side of that point, cruises coincide. Other
xovers confirm that NO3 data at southern end of section is clearly 5-10% too
low, while in the NE corner, data are somewhat better. Scrap.

Autogenerated comment - alkalinity

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : maintain 0. (Not verified to be
correct: inversion suggestion <<4, existing adjustment==0)

Autogenerated comment - tCO2

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make -999. No DIC samples were
measured on this cruise (the values CARINA refers to were calculated from AT and
pH). DIC samples were collected and shipped to SIO, but storage or analysis
there failed, and DIC_SIO shows a large spread and offset compared to
DIC_calc_on_board. This looks like a poisoning problem, with certain stations
affected more than others (judging from Goodhope&Dickson.doc).

90AV20041104 - oxygen

Average of all cross-overs is: 0.983
Inversion analysis suggests no significant adjustment: 1.005
There are only few cross-overs here.
Core cruises do not support an adjustment. Also some cruises which have too few
data to be included in the analysis do show qualitatively good cross-over
results with 90AV20041104.
Based on all this I suggest NO adjustment of oxygen of cruise 90AV20041104.

90AV20041104 - silicate

Average of all cross-overs is: 1.041
Inversion analysis suggests an adjustment of 3%: 0.970
However, the average cross-over has been very strongly influenced by one
outlier, 316N19831113 with an offset of 1.22
The other cruises, including core cruises, do not have a significant offset.
Based on this I suggest NO adjustment of silicate of cruise 90AV20041104.

90AV20041104 - phosphate

Average of all cruises is: 0.997
Inversion analysis suggests no significant adjustment: 0.989
There is relatively large variation around this cross-over point, e.g.
316N19831113 (which is high) and 35A319950222 (which is low).
The core cruises suggest no significant deviations.
Based on this I suggest NO adjustment of phosphate of 90AV20041104

90AV20041104 - nitrate

Average of all cross overs is: 0.986
Inversion analysis suggests no adjustment.
This cruise does seem to be a bit low with respect to core cruises.
Also, based on residuals of the N:P plot, which are quite low, a small
adjustment is suggested.
Based on this I suggest an adjustment of nitrate of 1.02.

Autogenerated update by AV for pH

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. Xovers/Inversion of calculated TCO2 from TALK and pH suggest no adjustment.
Probably a bit low, but below limit.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 0.99. Fair profiles, no
evidence of drift (as opposed to NO3 for this cruise). Cruise is 1-2% high, will
correct down by 1%, in accordance with results of various inversions. Clear
offset of -1% against AJAX-1 (which is 2% too high) confirm this.

90AV20041104 - phosphate

Average of all cruises is: 0.997
Inversion analysis suggests no significant adjustment: 0.989
There is relatively large variation around this cross-over point, e.g.
316N19831113 (which is high) and 35A319950222 (which is low).
The core cruises suggest no significant deviations.
Based on this I suggest NO adjustment of phosphate of 90AV20041104

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:

90AV20041104 - oxygen

Average of all cross-overs is: 0.983
Inversion analysis suggests no significant adjustment: 1.005
There are only few cross-overs here.
Core cruises do not support an adjustment. Also some cruises which have too few
data to be included in the analysis do show qualitatively good cross-over
results with 90AV20041104.
Based on all this I suggest NO adjustment of oxygen of cruise 90AV20041104.
