74JC19990315 - silicate

This cruise clearly appears to be too high. The weighted mean does indeed also
show this. The x-overs that would show that this cruise be too low, are not
convincing x-overs (variability and too different station locations for
comparison). I would even suggest a larger adjustment, namely 0.97 because of
this and the fact that especially the most recent x-over cruises are clearly
lower than the rest.

74JC19990315 - silicate

These silicate data are consistently high with recent cruises. Adjust down byh
3%

Posted by siv.lauvset@uib.no on 2018-10-01 10:31:27 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74JC19990315 - silicate

There are three "bad" outliers which distort the overall impression of at least
2% too high concentrations.
Other crossover agree nicely. Adjust downward.

74JC19990315 - salinity

Most offstes are within the acceptable range centered around 0. Maintain.

Posted by nlange@geomar.de on 2018-06-15 11:45:55 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74JC19990315 - phosphate

All crossovers - except for 316N1987 - have offsets smaller 1. Most offsets are
even below the 2% limit.
Note that some measurements hint towards bad precision (strong outliers) of the
datat, i.e. recheck 1st QC. Nonetheless, following the weighted mean adjust
upward.

Posted by nlange@geomar.de on 2018-06-15 11:45:33 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74JC19990315 - nitrate

Most offsets are within the accepatble range. Some of the more recent cruises
indicate slightly too high concentrations though (74JC2010).
But that is not enough evidence for a small adjustment especially given the fact
that cruises close to 1999 do not show strong Offsets. Maintain.

Posted by nlange@geomar.de on 2018-06-15 11:43:53 UTC for data product: GLODAPv2.2019, v2.2020, v2.2021, v2.2022, v2.2023

74JC19990315 - oxygen

All crossovers indicate too low concentrations, i.e. there is a nice agreement.
Further, the offset is quite consistent in depth. Adjust accordingly to 06AQ1998
- hence adjustment is rather on the conservative side...

74JC19990315 - silicate

This cruise clearly appears to be too high. The weighted mean does indeed also
show this. The x-overs that would show that this cruise be too low, are not
convincing x-overs (variability and too different station locations for
comparison). I would even suggest a larger adjustment, namely 0.97 because of
this and the fact that especially the most recent x-over cruises are clearly
lower than the rest.

These silicate data are consistently high with recent cruises. Adjust down byh
3%

74JC19990315 - silicate

There are three "bad" outliers which distort the overall impression of at least
2% too high concentrations.
Other crossover agree nicely. Adjust downward.
