Sea-floor Sediment and the Age of the Earth. Sea-floor sediments accumulate slowly, requiring millions of years for their current thickness. However, a catastrophic, global flood would also account for their current thickness. In this technical monograph, Dr. Vardiman develops an analytical model for sea-floor sediment accumulation based upon a global flood, young earth perspective. His model uses measured sedimentation rates, observed sediment depths on the sea floor, and a literal biblical time-frame. He concludes that present sea-floor sedimentation could have occurred within 5,000 years, and that there were several short “Ice Ages” following the Genesis Flood.
