18DD20170205 - phosphate

Likely this cruise has too low PO4 concentrations based on the crs analysis.
Most cruises (esp more recent ones) show an offset between 2% - 4%. However e.g.
there is a nice fit with 18DD200808… Further, the comparison to CANYONB does
also indicate a 2% offset, i.e. on the limit. Maintain with doubts.

18DD20170205 - oxygen

There are quite a bunch of (trustworthy) crs which do show a large (about 3%)
offset. However, many weighted means are also a bit misleading and negatively
influence the the total outcome. Further the CANYBONB comparison gives no reason
to believe that O2 is not accurate. All in all not enough for an adjustment.
Maintain with doubts.
