Seismic stratigraphy is critical to understanding the distribution, structure, and thickness of sedimentary formations. These data provide understanding of sedimentary history and critical information for safe and productive drilling. The seismic stratigraphy of the Demerara Rise and Ocean Drilling Program (ODP) Leg 207 drill site locations was established on the basis of existing industry multichannel seismic reflection data, high-resolution multichannel seismic reflection data, and ultra high resolution Parasound echo sounder data. In addition, a short single-channel seismic reflection line was run during ODP Leg 207 by the Underway Geophysics laboratory on the JOIDES Resolution. Figure F1 shows the cruise tracks over the Demerara Rise for data used in this study.
