attribute NC_GLOBAL summary String The dissociation constant of boric acid (KB) plays a critical role in marine carbonate system calculations, yet available parameterizations remain limited in salinity coverage and have not been revisited using modern methodology. This dataset combines Dickson (1990)'s data (i.e., D90) in synthetic seawater with our own work (i.e., MMB26) to produce an improved parameterization of pKB for carbonate system calculations across a full range of estuarine and open-ocean environments. MMB26 is a novel dataset of pKB obtained in natural seawater, derived from spectrophotometrically calibrated electrode measurements spanning salinities from 0 to 45.9 and temperatures between 275.15 and 308.15 K. This experimental data is particularly important given that nearly half the total variation in pKB across the full salinity range occurs within the narrow freshwater-to-brackish transition. The spectrophotometrically calibrated electrode data (MMB26) are in excellent agreement with previous work obtained in synthetic seawater at salinities greater than 5 (D90).
