Data was acquired using an EdgeTech GEO-STAR SUBBOTTOM PROFILER system with an SB-424 tow fish sending a 4-24 kHz frequency pulse.

Seismic lines were processed using the GEO-STAR Full Spectrum Sonar computer program.

Reflections have been correlated to cores based on visual comparisons and preliminary grain size data.

Note that fine-grained sediment overlying coarse-grained sediment typically infers a transition from mud to sand.

Similarly, coarse-grained sediment overlying fine-grained sediment is indicative of a transition from sand to mud within the core.

Navigation was obtained using DGPS.
