Abstract
Abstract Seismic wave detectors are located along a plurality of spaced apart parallel detecting lines. A plurality of seismic wave transmitting stations are located along a plurality of transmitting lines which are substantially perpendicular to the detecting lines at one end thereof. Seismic waves are generated from sequential ones of the transmitting lines and are received by the detectors to provide three-dimensional common depth point coverage of the earth''s subsurface.
