Figure 11. Peak interstitial water alkalinity vs. organic carbon mass accumulation rate. There is a general linear correlation between the two parameters. Three sites are the furthest from the trend: Site 1022, the only drill site with a >2 m.y. hiatus at the top; Site 1019, with gas hydrates; and Site 1017.
