18DD20160208 - 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 CANYONB comparisons also
indicates 2% low data. Note that all cruises younger 2010 seem to have low PO4
concentrations compared to historical data... Maintain with doubts.

18DD20160208 - tco2

Weighted mean offset is a bit misleading as samples at depth fit well with
historical data. Especially at two depth levels (sigma 4= 45.75 - 45.8) offsets
become relatively large ( about 5- 10 umol/kg) however. Comparisons to CANYONB
samples also indicate too low concentrations (especially at those depths...).
Maintain with doubts.
