SEAM Phase II — surface waves in land seismic exploration

A special challenge of land seismic exploration is dealing with elastic surface waves at the Earth-air interface. These waves (commonly called "ground roll") are induced by free-surface boundary conditions that hold when an elastic solid (Earth) is in contact with free space (air, effectively) and are generally the slowest decaying and slowest moving events on shot gathers.
