Notes: The corrections are based on dissolved sulfate concentrations, assuming zero sulfate concentration below the sulfate/methane interface, which at this site occurs in the uppermost 2 m. * = no interstitial water squeezed because of poor quality of sample, ** = analyzed for only a few elements because of extensive contamination with drill fluid. — = no data.
