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.

318M19771216 - phosphate

Bergen meeting 2012: We decided to not apply an adjustment for phosphate for
this cruise; it is only 1%, i.e. lower than the threshold, and the data are
pretty old (i.e. could be natural variability or trends)

Posted by ttanhua@geomar.de on 2012-11-13 16:04:48 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

318M19771216 - oxygen

Offset with 3 cruises: 1.007
Inversion suggests: 0.997

Orig. GLODAP applied a slight +0.03 (additive),
which is much smaller than the 1% threshold.

We suggest NO adjustment, also in agreement with CARINA.

318M19771216 - silicate

Offset with 3 cruises: 0.990
Inversion suggests: 0.996
No additional info to justify a correction.
We thus suggests NO adjustment, in agreement with CARINA.

318M19771216 - phosphate

Offset with 3 cruises: 0.987
Inversion suggests significant correction: 1.020

This cruise seems to be on the low side which is confirmed by not-counting
xovers. In CARINA inversion also suggested a small correction, but there was
some discordant info as well.

We think an adjustment is justified, though not to the full extent of the
threshold (2%). We thus suggest an adjustment of 1.01

318M19771216 - nitrate

Offset with 3 cruises: 1.014
Inversion suggests: 0.996
Also not-counting xovers point to good data.
We suggest NO adjustment, in agreement with CARINA.

Posted by mario.hoppema@awi.de on 2012-07-25 10:54:30 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

318M19771216 - alkalinity

Offset with 2 cruises: +5.4
Inversion suggests: -2.1

The high offset is caused by the xover with cruise 35MF19850401,
which got an adjustment of -7.

Thus, we suggest NO adjustment, in agreement with orig. GLODAP and CARINA.

Posted by mario.hoppema@awi.de on 2012-07-25 10:48:33 UTC for data product: GLODAPv2, v2.2019, v2.2020, v2.2021, v2.2022, v2.2023

318M19771216 - tco2

Offset with only two cruises: +21
Inversion suggests: -19.2

Orig. GLODAP applied -22.5, while CARINA suggested -23
(Lo Monaco et al 2010 ESSD).

Also from other not-counting xovers it is clear this cruise is much too high.
We decided to follow CARINA (and orig. GLODAP) because
these are based on more data, and thus suggest an adjustment of: -23

318M19771216 - salinity

Offset with 3 cruises: +3.2 ppm
Inversion suggests: -2.4 ppm

Orig. GLODAP applied +1.4 ppm

As this is all below the threshold of 5 ppm and the info
does does justify to correct, we suggest NO adjustment.
