Abstract

This paper considers the effect of a pressure point moving over the surface of a fluid which is composed of two layers of different densities, the lower layer being of infinite depth. The method is the same as that used by Crapper (1964) for the same problem with a uniform fluid. The resulting waves are in two sets, the first being the normal surface wave for the uniform ocean, with a slight change in amplitude, and the second an internal wave. The crests of the internal wave have a pattern similar to that of the surface wave for a shallow uniform fluid.
