... provides a means to rapidly evaluate extensive areas of the seafloor . Introduction This paper presents a method for determining the compressional velocity and bulk density for marine sediments using multi-channel, high resolution seismic data. The seafloor interface presents a unique case because...

... pressure logs are computed against depth, making use of the above seismic velocity and density logs. Formation pressure logs are calculated assuming that compressional velocity, mean density, and depth are proportional to formation pressure. These logs are constrained at every depth point by estimated...

.... Significant research has been conducted on the relationship of seismic velocity to rock and soil strength in the U.S. and particularly by the seismologists in the Soviet Union. This work has been primarily focused on the foundation of earth fill dams. seismic velocity compressional velocity...

... seismic velocities ranging from 5.5 to 6.5 km/sec. The basin fill consists of three major units distinguishable on the basis of compressional velocities; unconformities appear to separate each of these units. The basal unit, with a velocity of 4.9 km/sec, occurs only in the deeper central portion...
