Time series of pH measured detected by a passive flow SeaFET pH instrument deployed
during the 1 month MLML field trial.
Top Panel
: Continuous pH
Total
recordings from instrument (blue

Total
of adjacent grab samples determined by mCP dye (red circles). Instrument values are
pHext corrected for ambient T and S using processing software provided with the SeaFET application.
Bottom Panel
: Difference in measured pH relative to reference samples (Instrument – Dye Ref) observed
during deployment. Zero offset is represented by dashed line as pH
Total
scale is reported the SeaFET pH
sensor and the dye reference method.
