49UP20210728 - silicate
There is a strong agreement between the individual crossover offsets for a 1%
offset (see also low standard deviation of absolute weighted mean). The offset
is constant in depth and also reflected in the CANYON-B analysis. Adjust
downward accordingly.

All tracer concentration show a strong undersaturation (up to 25%). The ratios
(all depths) would benefit from an upward adjustment of CFC_11.

49UP20210728 - cfc113
Undersaturation based on warm waters not surprising.

High concentrations excluded and all other look fine.

49UP20210728 - cfc113
If CFC_11 gets adjusted so must CFC113 based on the saturation ratios…

18DL20200722 - cfc11
All tracer concentration show a strong undersaturation (up to 25%). The ratios
(all depths) would benefit from an upward adjustment of CFC_11.

Maintain - 10% undersaturation seems natural.

49UP20210728 - silicate
There is a strong agreement between the individual crossover offsets for a 1%
offset (see also low standard deviation of absolute weighted mean). The offset
is constant in depth and also reflected in the CANYON-B analysis. Adjust
downward accordingly.
