Figure F2. Seismic reflection profile across Site 1219. The sedimentary section is marked by a weakly reflective unit, ~38 ms two-way traveltime (TWT) below the seafloor, assumed to be clays. Below, between 38 and 219 ms TWT, are units bounded by the Y, P5, P4, and P3 seismic horizons (see Lyle et al., this volume) that we assigned to lower Miocene-upper Eocene sedimentary units.
