Abstract : The respon%e of vertical arrays at single frequencies (C%V) and for homogeneous media is well known. This paper addresses the issues of frequency dependence and sound velocity gradients for the vertical array response in a deep ocean. I have modified the synthetic seismogram code of Neil Frazer, Subhashis Mallick and Dennis Lindwall to address this problem. The code uses a rearrangement of the Kennett reflectivity algorithm (Kennett, 1974,1983) which computes the geoacoustic response for depth dependent media and pulse sources by the wave number integration method.
