High-resolution multichannel seismic data were collected in the study area by W.S. Holbrook and coworkers during a cruise in 2000. These data provide critical information about the deeper and larger-scale sedimentary and flow features in the subseafloor. The vertical axis is approximately 750 meters. The new subseafloor images being acquired during Windows to the Deep will yield greater detail about the uppermost 20 to 50 m of the sedimentary section.
