74EQ20151206 - nitrate

Crossovers in the west show good matches while eastern crossovers indicate too
low nitrate concentartions - also clearly present in the repeated crossovers.
Nonetheless, phosphate values are also high compared to previous cruises. Not
enough to justify an adjustment within the limits. Further, as watermass
characteristics clearly change going from east to west and individual profiles
look internally consistent I cannot suggest to dismiss data based on this rather
small east-west deviations.
Maintain.

74EQ20151206 - nitrate

This cruise did measure nitrate - will be included in the next GLODAP version.
See original data file for data (not Qced!).

74EQ20151206 - silicate

There looks to be aconcentration dependent offset here. Data are sent back to PI
for primary QC and possible calibration curve adjustment

74EQ20151206 - silicate

Especially 316N cruises and repeated tracks (e.g. DI2010) show offsets above the
upper 2% limit. But, ignoring MT1997 (bad crossover), the weighted mean is still
within the acceptable range. Since 33RO1998 is supposed to be dead accurate the
proposed adjustment is heavily based on it's offset (1.04). Hence adjust
downward (accordingly to the weighted mean) to - at least - reduce the offset.
Note that MT1997 is non Q-ced;"

74EQ20151206 - salinity

Most offsets are within the acceptable range with positive and negative offsets
present. Note that especially at greater depth the offset often minimalizes.
Further, HE2003 shows a very doubtful result. Maintain.

74EQ20151206 - phosphate

Most offsets are within the 2% range, but especially the "repeated crossovers"
indicate that concentrations seem 1-2% too high… Nonetheless, that alone is not
enough evidence for a corresponding adjustment.

Posted by nlange@geomar.de on 2018-06-15 10:45:46 UTC for data product: GLODAPv2.2019

74EQ20151206 - oxygen

All offsets are clearly within the acceptable range indicating nice quality of
the data. Maintain.

Posted by nlange@geomar.de on 2018-06-15 10:44:56 UTC for data product: GLODAPv2.2019

74EQ20151206 - alkalinity

All crossovers indicate too low concentrations - i.e. there is a nice agreement
between all crossover results.
The individual offset is variable but visible at all depths. Adjust upward
accordingly to the weighted mean offset.
