Figure 3. Sediment grain-size distribution (lines) and pore-water chlorinity (solid circles; after Paull, Matsumoto, Wallace, et al., 1996) in the column at ODP Site 994. Grain-size fractions in millimeters: 1 = >0.05; 2 = 0.05-0.01; 3 = 0.01-0.005; 4 = 0.005-0.001; 5 = <0.001. Bold lines limit the gas hydrate zone.
