Submarine outcrop and acoustic expression of lithified sediment layers in northwest Providence Channel, Bahamas Academic Article uri icon

abstract

  • Visual observations of the wall of Great Bahama Canyon indicate that ledges produced by differential submarine erosion occur at depths like reflectors on high-resolution seismic profiles, suggesting lithologic changes produce acoustic impedance contrasts and therefore reflectors. Quaternary-aged sediments in a core from Little Bahama Bank exhibit changes in lithology (and presumably acoustic impedance) associated with glacial-to-interglacial transitions, which also correspond in depth to seismic reflectors. This supports the concept that reflectors on high-resolution seismic profiles of Bahamian periplatform ooze correspond directly to changes in lithology and may be associated with climate/sea level fluctuations.
