096U20180110 - alkalinity

Adjusted following RG meeting (March 2020)

Posted by nlange@geomar.de on 2020-05-18 10:45:26 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110

Following the Reference Group meeting small adjustments for TA and Si have been
agreed on.

Posted by nlange@geomar.de on 2020-04-01 17:47:22 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - alkalinity

Similar crossover results as for DIC. For alkalinity the offset is worse
however, but again still within the limits... Maintain with doubts!

Posted by nlange@geomar.de on 2020-03-30 13:23:57 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - tco2

Quite difficult decision as all crossover cruises show a clear positive offset.
However, 10 out of 11 offsets are still within the limits and offsets also ofetn
decrease with depth... Given this is a variable region and the most recent
crossover (6 years old) actually shows the best match - maintain.

Posted by nlange@geomar.de on 2020-03-30 13:22:32 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - cfc12

Good fit between CFC_11 and CFC_12 both roughly 5 % undersaturated (close to
Antarctica - natural). Maintain.

Posted by nlange@geomar.de on 2020-02-17 12:23:50 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - cfc11

Good fit between CFC_11 and CFC_12 both roughly 5 % undersaturated (close to
Antarctica - natural). Maintain.

Posted by nlange@geomar.de on 2020-02-17 12:23:33 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - silicate

All weighted means indicate that crs cruises have lower concentrations in
general. However, individual samples especially at depth do not seem to be
lower. I.e. maintain.

Posted by nlange@geomar.de on 2020-02-17 12:23:18 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - phosphate

Maintain.

Posted by nlange@geomar.de on 2020-02-17 12:22:59 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - oxygen

Good accuracy. Maintain. Note that the one sample with O2>280 will be flagged
bad following a repeated 1st QC.

Posted by nlange@geomar.de on 2020-02-17 12:22:45 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - nitrate

All crs offsets but the one from 09AR19930404 (received a quite dubious downward
adjustment) show a good match. Accurate data. Maintain.

Posted by nlange@geomar.de on 2020-02-17 12:22:20 UTC for data product: GLODAPv2.2020, v2.2021

096U20180110 - salinity

Hard to give a robust conclusion given the large uncertainties at even a minimum
depth of 2000m… However since 2003 no offset is outside the range and the
absolute weighted mean is also within the limits. Maintain with doubts. Note
that data itself look good.
