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 1.02. These data are
borderline acceptable. Strong station-to-station jumps at western end of
section, but much less so than for PO4. Eastern 2/3rd of section is of
sufficient quality.

Autogenerated comment - alkalinity

Auto-uploaded comment from GLODAPv2 assessment by Steven van Heuven (src:
GLODAPv2_ATL_for_Carsten.xls / 2015-01-08): : Make -777. Only three deep
profiles, each fairly noisy, and apparently offset from each other. Too few
xovers to assess, and likely bad.

06MT19910210 - phosphate

although the mean offset is only 0.99, the cruise appears to be low.
The new inversion for phosphate in the Atlantic with 10 core cruises assigned
suggests an adjustment of 1.04 which is more in line with the mean offset. I
suggest to follow this.

06MT19910210 - tco2

Mean offset -1.6 which is not significant.
Inversion only suggsts +0.6
Thus NO adjustment.

06MT19910210 - alkalinity

No value for mean offset because of no valid x-overs. However, some non-valid
x-overs suggest that this cruise is too high. GLODAP v1 suggested an adjustment
of -7 which we will also adopt.

Posted by mario.hoppema@awi.de on 2012-11-16 14:58:03 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

06MT19910210 - phosphate

The inversion suggested a correction of 1.0648, based on 9 crossovers with a
mean offset of 0.991. The reason for the small offset is the fact that the
inversion suggested corrections for most of the cruises which we compare with.
Adjusting for this brings the mean offset to ~0.97, i.e. the data are low. I
recommend that these data are adjusted by 1.06.

06MT19910210 - oxygen

The inversion suggest that the data should be corrected by x0.9931, based on 10
crossovers with mean offset 1.000. The data appear fine, if not slightly high.
This is completely opposite to GLODAP finding these as low as the previos
cruise! They aren’t. Compare for instance crossover with 35A319950111. Do not
adjust.

06MT19910210 - silicate

The inversion suggest a correction of 1.0178 and the mean offset is 0.986. Looks
slightly low. Took place in South equatorial Atlantic. Suggest that this cruise
is adjusted by 1.02. This is ~in accordance with GLODAP, finding it 3.2 μmol/kg
too low.

06MT19910210 - nitrate

Suggested correction is 1.0136, with mean offset 0.991. Seems fine, do not
adjust these data.

06MT19910210 - salinity

Inversion suggested correction of 1.67 ppm based on 9 crossovers with a mean
offset of -2.011 ppm. Do not adjust.
