Johnson (1971) has made a useful contribution to ocean-circulation theory by establishing more definitely the role of the thermal structure in the larger context of the theory of wind-driven ocean circulations. However, serious objections should be raised to his treatment of the eastern-boundary region and to his results on coastal upwelling.
