Figure 18.
Time series of pH measured by a SAMI-pH(PR) instrument deployed during the 1 month
GLERL field trial.
Top Panel
: Continuous pH
Total
recordings from instrument (blue line) and pH
Total
of
adjacent grab samples determined by phenol red dye (red circles).
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 by both the SAMI-pH sensor and the dye reference
method.
