Abstract
A simple, qualitative model is proposed to explain some of the prominent feature s in the near-surface current observations in Robeson Channel reported previousl y. The current profile associated with Kelvin waves in a homogeneousbody of wate r in a channel is extended to a layered channel with sharp discontinuity in dens ity. Initially only one interface at about 50 m is assumed to explain the near-s urface current pattern. In addition to disrupting the vertical continuity of the transverse current, the interface is also assumed to respond to the transverse oscillations of the sea surface created by the tide moving in and out of the cha nnel, thereby affecting the speed distribution of the lateral current.
