Abstract
In 1969 the USNS Elisha Kane completed an extensive geophysical investigation of the Gulf of Mexico. One of the principal measurement systems used was the medium-frequency (3,500 Hz), high-resolution seismic profiler. The seismic profiles obtained with this system provide information about the effects on recent sediments of deposition, water-energy levels, and diapirism. The various stages of sediment deformation and disruption associated with active diapirism and of faulting resulting from salt dome emplacement are observable. It is concluded that the medium-frequency seismic system is a useful tool to aid the study of concurrent deposition during active diapirism and the subsequent environmental effects at the sea floor.
