Figure F2. A. Map showing sites drilled during Leg 204. Locations of vertical slices from the 3-D seismic volume are also shown. Colored shading shows the gas hydrate content of the sediments averaged from the seafloor to the bottom-simulating reflector (BSR). Numbers in parentheses indicate the color scale for B–F. B–F. Slices from the 3-D seismic volume. Gas hydrate content in different regions is shown by color overlays. A, B, and B´ are bright reflections that were found to correspond to relatively coarse grained strata containing volcanic ash. AC is the older, more lithified and fractured, accreted sediments, which are overlain by uplifted and slightly deformed slope basin sediments (adapted from Tréhu et al., 2004b).
