pH details from A. Borges:
pH measurements were carried out with a combined electrode (Metrohm 6.0232.100), calibrated on the Total Hydrogen Ion Concentration Scale, using TRIS (2-amino-2-hydroxymethyl-1,3-propanediol) and AMP (2-aminopyridine) buffers prepared at a salinity of 35 following Dickson (1993, Marine Chemistry 44, 131-142), and using the pK for TRIS given by DelValls and Dickson (1998, Deep-Sea Research Part I 45, 1541-1554), and the pK for AMP given by Dickson (1993, Marine Chemistry 44, 131-142). pH was corrected to in-situ temperature using total alkalinity data, and the dissociation constants for carbonic acid given by Mehrbach et al. (1973, Limnology and Oceanography 18:897-907) as refitted by Dickson and Millero (1987, Deep-Sea Research Part I 34:1733-1743).
