Dispersed shots at optimum depth - an efficient seismic source for lithospheric studies

Main Article Content

A.W.B. Jacob


The case for dispersing charges fired at sea into a number of packages fired simultaneously at optimum depth is outlined and an experiment, carried out to check that linear addition of the signals from separate sources does occur, is described. The advantages of this system for lithospheric studies are demonstrated.
