On-Bottom Seismographs for Shallow Seismic Imaging of the Continental Shelf Seabed
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 was to construct 9 on-bottom seismographs suitable for high-resolution, seismic imaging of the shallow (< ~100 m) seabed of the continental shelf and upper slope. While many U.S. institutions, including WHOI, operate ocean bottom seismographs (OBS), none of the existing OBS designs is suitable for imaging compressional-wave and shear-wave structure on the requisite scale of meters to tens of meters. This area of research is of growing interest to geologists, engineers, and environmental scientists.
