Long-term Monitoring of pH, total alkalinity, the stable oxygen isotopic composition of water and the stable carbon isotopic composition of dissolved inorganic carbon in the Canadian Arctic
pH was measured onboard by spectrophotometric determinations using phenol red and m-cresol purple at 25°C. TA (Titration alkalinity) was measured onboard, by automatic potentiometric titration with a weak HCl solution. d18O(H2O) was stored in screw cap plastic test tubes. Analyzed on a Micromass Iso...
