18HU20160430 - salinity
There is clearly a strong temporal trend towards saltier waters visible (roughly
0.02PSU per decade). As the trend is still ongoing (see other, more recent HU
cruises) the salinity data seems to be accurate. Maintain.

18HU20160430 - tco2
Crossover offsets with normalized tco2 show that data fits nicely to temporal
trend. Maintain.

18HU20160430 - alkalinity
All crossover offsets - but two - with normalized TA are within the acceptable
range. Note that the regional data is very scattery though, i.e high
uncertainties are common. Maintain.

18HU20160430 - ph
Very uncertain crossover results but within acceptable range (offset <0.1). The
interconsistency check (type 2) agrees very well with the crossover result (mean
offset of 0.008). As both analyses are below the threshold - maintain.

18HU20160430 - phosphate
The concentrations might be slightly too high. However, given the large
uncertainties and that the weighted mean offset is actually slightly below the
upper limit do not adjust. Maintain.

18HU20160430 - nitrate
The data is extremely scattery, but it is quite obvious that the data of the
2016 cruise is in all cases on the lower end of the range. The good agreement
between the crossovers is also striking. Thus, even though standard deviations
are large, there is strong evidence that the nitrate concentrations are biased
low. Adjust upwards following the weighted mean. This improves the Redfield
ratio too.

Due to the extreme scatter of the historic and present data no trustworthy 2nd
QC is possible.

Even though there seems to be an underlying temporal trend involved, it can
clearly be seen that the data is accurate. All crossovers with cruises younger
2006 have offsets very close to 1. Maintain.

Quite scattery surface data - maybe slightly low but still in the acceptable
range (especially given the strong variability of this region). Maintain.
