Abstract : A formal solution is given to the problem of propagation of an acoustic pulse in a medium with a free surface, below which the speed of sound is a slowly decreasing, linear function of depth. The pulse originates from a point source at a fixed depth below the surface. The solution applies in part of the region where the front of the pulse is inclined to the free surface, and can therefore be used to calculate the effect of transverse gradient in velocity of sound on the pulse shape.
