Ocean Waves: Half-a-Century of Discovery

While the nature of most ocean waves has long been known and their basic physics understood since the nineteenth century, intense study of ocean waves during the second half of the twentieth century has taken the subject from the realm of mathematical exercises to that of practical engineering. Modern understanding of the generation, propagation and interactions of ocean waves with each other and with oceanic features has advanced to a quantitative level offering predictive capacity. This paper presents a brief qualitative review of advances in knowledge of sound waves, wind waves, tsunamis, tides, internal waves and long-period vorticity waves. The review is aimed at non-specialists who may benefit from an overview of the current state of the subject and access to a bibliography of general-interest references.
