Helpful and stimulating comments from the following people are gratefully acknowledged: Eric D'Asaro, Eric Kunze, Mitsuhiro Kawase, Charlie Eriksen, Knut Aagaard, Parker MacCready, Jody Klymak, and Mark Prater. The vertical mode MATLAB code was cheerfully supplied by Gabe Vecchi and Sebastian. Hydrographic data was taken during the spring 1994 cruise of the C.S.S. Hudson, with John Lazier as chief scientist. Support for J. Lilly from a NDSEG Graduate Student Fellowship was greatly appreciated.
