Figure F1. A. Methane concentrations for Site 1230 derived from gas void analyses. Circles = mean of calculated concentrations based on equations 7 and 8. Error bars cover the range of the values. Squares = concentrations derived from PCS measurements (Dickens et al., 2003) calculated following Milkov et al., (2003). B. Chloride vs. depth for Site 1230 (D'Hondt, Jørgensen, Miller, et al., 2003).
