GLODAPv3 release: autogenerated alkalinity update for 49UP20160608

49UP20160608 - alkalinity
Quite eveident from the crs analysis that data is biased low. Only 3 out of 19
crs offsets are within the acceptable range but all are still negative and two
of them are even below -2 umol/kg. The agreement between all crs offsets is
striking as well as the offset is constant with depth. However the more recent
crs (younger 2011) show slightly lower offsets. Analysis itself is robust, e.g.
entire cruise track is covered with crs. Adjust according to the more recent
crs.

49UP20160608 - ph
A temperol trend in the crs offsets is visible towards a better fit with time.
Hence the weighted mean is too low, i.e. closer to zero. Good fits with the more
recent (younger 2011) crs. Interconsistency check indicates slightly too low
values but the offset of -0.0083 +/- 0.0110 is still within the range and quite
uncertain. Maintain.

49UP20160608 - phosphate
As the other UP2016 cruises this cruise shows phosphate concentrations rather on
the low side. Further, all crs offsets are still within the acceptable range. No
reason to expect that this cruise is biased. Maintain.

Maybe slightly too high concentrations but not enough evidence to justify an
adjustment. Even though roughly 60% show an offset above 1% and only 1 out of 22
crs has an offset below 1, the standard deviations are just too large for such a
small adjustment. Maintain.

49UP20160608 - nitrate

49UP20160608 - ph
A temperol trend in the crs offsets is visible towards a better fit with time.
Hence the weighted mean is too low, i.e. closer to zero. Good fits with the more
recent (younger 2011) crs. Interconsistency check indicates slightly too low
values but the offset of -0.0083 +/- 0.0110 is still within the range and quite
uncertain. Maintain.

49UP20160608 - silicate
Maybe slightly too high concentrations but not enough evidence to justify an
adjustment. Even though roughly 60% show an offset above 1% and only 1 out of 22
crs has an offset below 1, the standard deviations are just too large for such a
small adjustment. Maintain.

49UP20160608 - phosphate
As the other UP2016 cruises this cruise shows phosphate concentrations rather on
the low side. Further, all crs offsets are still within the acceptable range. No
reason to expect that this cruise is biased. Maintain.

49UP20160608 - alkalinity
Quite eveident from the crs analysis that data is biased low. Only 3 out of 19
crs offsets are within the acceptable range but all are still negative and two
of them are even below -2 umol/kg. The agreement between all crs offsets is
striking as well as the offset is constant with depth. However the more recent
crs (younger 2011) show slightly lower offsets. Analysis itself is robust, e.g.
entire cruise track is covered with crs. Adjust according to the more recent
crs.
