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.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make 0.99, but this is borderline.
Cruise is exactly 1.0±0.5% lower than exact repeat occupation RO2011, which the
inversion considers perfectly accurate.

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : make -777. Calibration break in TA
data. Data west of 34oW are bad. Data deeper than 1000m are biased ~15 umolkg
too high, while shallow data are around 30 umolkg too low. Data east of 34ºW
compare well with (among others) 33RO2011 except the station at 25oW, which is
severely miscalibrated. FIGUREALK_change_06MT19921227_33RO20110926.pdf

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:

06MT19921227 - alkalinity

More information available with the complete GLODAPv2 set. Inversion suggest
-10, so we adjust back to "no adjustment"

06MT19921227 - phosphate

New inversion for phosphate in the Atlantic with 10 core cruises assigned
confirms that NO adjustment should be applied.

06MT19921227 - alkalinity

Mean offset with 2 cruises -8.8
One large negative x-over with 323019940104 gets less negative by adjustment of
latter cruise.
Inversion suggests +10.8
This cruise seems to be low.
I suggest to follow the inversion and give adjustment of +10

06MT19921227 - tco2

Mean offset of 4 cruises: 4.9
Inversion suggests insignificant adj of -1.5
I suggest NO adjustment, in agreement with GLODAPv1

06MT19921227 - silicate

The inversion suggested a correction of 1.02, with a mean offset of 0.97, based
on 10 crossovers. The data appear low, adjust by 1.02.

Posted by are.olsen@uib.no on 2012-09-24 10:02:58 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

06MT19921227 - phosphate

Inversion suggested correction of 1.0231 and the mean offset was 1.027. The MO
is biased by the fact that many of the cruises involved in the crossovers are
biased. After correcting for this I get a mean offset of 0.997. There is not
enough evidence to adjust these data.

06MT19921227 - oxygen

The inversion suggest a correction of 0.9915 based on 10 crossovers with a mean
offset of 1.01. These do not agree particularly well in magnitude, but most
suggest the data are high. I am quite uncertain, do not adjust.

06MT19921227 - nitrate

Suggested correction is 0.971 and the mean offset is 1.04 and the data appears
high. We recommend that these data are adjusted using a factor of 0.97. This is
consistent with GLODAP recommending a reduction of 0.92 umol/kg.

06MT19921227 - salinity

Inversion suggested correction of 2.2 ppm, based on 10 crossovers with a mean
offset of -1.7. Do not adjust.
