Tomographic Imaging of the Shear Wave Velocity Structure of the Shallow Seabed of the New Jersey Continental Shelf
1998
Collins, John A. | Ewing, John I.
The long term goals of this project are to map the three-dimensional, shear-wave velocity structure of the upper 50-100 m of the seabed, to correlate these measurements with geological structure, and to use the spatial variability in shear-wave structure to understand the depositional and erosional processes responsible for the measured structure. The objective of this work is to carry out a three-dimensional refraction/interface-wave tomography experiment on the continental shelf offshore New Jersey in an area that has been extensively surveyed with high-resolution, seismic reflection imaging techniques. The motivation is our belief that, in many geological settings, the internal structure and geometry of sedimentary facies are sufficiently complex that they can be determined only by carrying out a three-dimensional experiment. Mapping the geometry of these sedimentary facies is an essential component to any study that aims to provide physical constraints on the processes governing sediment deposition and erosion and their evolution over time.
