Using finite difference methods, the effect on long waves of a coastal shelf in a rotating hemispherical basin, symmetric about the equator, is studied. Of the four modes investigated, with a shelf added to a constant-depth basin, two modes respond weakly: one is a planetary mode antisymmetric in the sea surface about the equator; the other is a gravity mode symmetric in the sea surface....
