Reprocessing of Marine Multichannel Seismic Reflection Profile Line 12, Cape Hatteras, North Caroline, to Shell Mohawk Well, Canada.

摘要

U.S. Geological Survey marine multichannel seismic reflection profile Line 12 traversed 1,437 kilometers from Cape Hatteras to the Shell Mohawk well in Canada. Because of questionable velocity information and the poor quality of the original data processing done in 1978, reprocessing was requested. Five features were selected from the reprocessed line, all of which showed that with careful editing of data and careful management of certain key parameters in the software modules, the seismic image of grabens, salt domes, and deep crustal reflectors throughout the profile were enhanced, enabling a more accurate interpretation of the data.
