29AH20110128 - salinity
All offsets are within the acceptable range, except MT1997 (bad crossover). All
in all the data shows good accuracy. No need for an adjustment.

29AH20110128 - ph
The pH measurements was done using the mcp of sigma and the Clayton&Byrne'93
recipe. We does not add the delValls & Dickson (1998) correction of 0.0047.
Our previous crossover also confirm a slight low pH.
Thus, I agree to add at least the 0.0047 DelVall correction or directly the
0.0075 proposed by Nico

29AH20110128 - ph
All but one - of doubtful quality - crossover (316N1981) have negative offsets.
Even though 316N1997 shows a much stronger offset than other cruises I would not
disregard it. Hence, the crossover results seem reliable. Following the weighted
mean of -0.0075 an additional inter consistency check has been performed (type
3). The calculated tco2 offset was reduced from 5.57 (no pH adjustment) to 2.40
(pH + 0.0075). All in all I would suggest an adjustment upward of 0.0075.

All offsets within acceptable range, indicating slightly too low (<1%)

29AH20110128 - nitrate
All but one offset indicate too low nitrate concentrations.
Also, in total only three crossovers show acceptable offsets. With the suggested
adjustment concentartions are very close to 33AT2012 which seem fine. Adjust 5%
upward.

29AH20110128 - silicate
In december '2019, I had contact with Francisco Dominguez that he did the
nutrient analysis during the cruise, in order to check the calibration curves of
silicate becasue they are ussually non-linear and some people do not take this
into account.
He said me that he did not have the file data to work in it. Thus, it is
impossible to go backward and try to recalibrate de silicate numbers.

29AH20110128 - silicate
There seems to be an issue with offset based vs concentration, i.e. high offset
at low concentration. Flag the data (that are high precision) to the PI for
recalibration

There are several trustworthy offsets above the max limit, e.g. 33RO2003. But
there are also several below the min. limit, such as 316N1997/2003.
Excluding 06MT1997 (due to bad locations of the crossover stations), the
weighted mean offset still is 1.0197. Nonetheless, this is within the range,
thus no adjustment.
