Notes on availability of multi-channel seismic processing programs

During the past two years, a seismic processing system has been developed within Western Region offices of the U.S. Geological Survey (Pacific-Arctic Branch of Marine Geology). This brief report describes some of the programs within this system that may be of value to others. We process seismic reflection data taken onboard ship to yield a pseudo cross section of the earth as revealed by echoes returned off rock layers within the earth.
