aYes = pH values are normalized by using certified reference materials (CRMs) calibrated on shore. No = pH values were not referenced to CRMs.
bRecommendation of Kitack Lee and Frank Millero whether pH is reliable for crossover analysis and internal consistency. OK = recommended, No = not recommended.
cMeasured on the National Bureau of Standards (NBS) scale at 15°C but reported at 25°C seawater scale by principal investigator (A. Rios).
dUnknown.
eReported on the NBS scale.
fNot deemed reliable (Millero, personal communication).
