Abstract: A method is described for seismic modeling implemented on a computer system including multiple computer nodes, which includes receiving, at a computer processor, a 4D speed of sound in water library and a marine seismic survey geometry; creating, via the computer processor, a full survey 3D Earth model for each seismic shot time based on the 4D speed of sound in water library to generate a set of dynamic 3D Earth models; simulating 4D seismic shots for the set of dynamic 3D Earth models by simulating multiple shots on each node to generate a set of 4D seismic shot gathers; and outputting the 4D seismic shot gathers.
