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:6; 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.

inspected, but inversion says abs(adj)<0.5% and existing suggestion is also
<0.5%

>10% off) is also 3-4%.

06MT19910902 - phosphate

New inversion for phosphate in the Atlantic with 10 core cruises assigned does
not change the previously suggested adjustment.

Posted by mario.hoppema@awi.de on 2013-01-09 16:34:53 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

06MT19910902 - tco2

Mean offset is -5.3 This cruise is consistently low. Some of the x-overs are
with cruises in CARINA which don't need an adjustment. Differences with other
cruises are not dependent on the year of the cruises.
Inversion suggests a correction of +5.4
We propose an adjustment of +5 (not following GLODAP v1 where no adj was given).

06MT19910902 - alkalinity

Very large spread and offsets of 60-70. Data flagged bad.

06MT19910902 - phosphate

Bergen workshop revised adjustment to 0.94, comparisons witjh the 1996 & 1997
Knorr cruises and the 1994 06MT cruise should weight most.

06MT19910902 - oxygen

The inversion suggest a correction of 1.003. Mean offset is 1.004. No
adjustment is recommended.

06MT19910902 - silicate

Inversion suggest correction of 0.984 and mean offset is 1.02. Subpolar gyre
cruise at 2% limit. Does not appear consistently off, do not adjust.

Posted by are.olsen@uib.no on 2012-09-12 20:55:00 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

06MT19910902 - phosphate

The inversion suggested a correction of 0.9061. Mean of all offsets was 1.039,
and it looks high, also towards the east NA, which should be more stable in
time. We recommend that the cruise is adjusted by x0.91. Direction is consistent
but magnitude is twice the GLODAP adjustment of -0.054.

06MT19910902 - nitrate

The inversion suggest an correction of 0.98. Mean of all crossovers is 1.009,
which is below the 2% limit: The data are high compared to some, but low
compared to other cruises. The cruise crossed the Iceland and Irminger basins,
which have witnessed substantial variations over the 90s. Given these
circumstances the evidence is inconclusive and no adjustment is recommended.

06MT19910902 - salinity

Inversion suggested a correction of 3.63 ppm based on 9 crossovers with a mean
offset of -2.8 ppm. Do not adjust.
