Foam patches left by waves breaking as they approach a smooth and gently sloping beach from a near-normal direction sometimes have the distinctly triangular shape that has been studied by Turner and Turner (2011). Explanations of the size of the angle at the apex of the triangles observed by Turner and Turner are suggested in terms of physical processes that determine the speed at which the point of breaking travels along a wave crest. These explanations differ from the entrainment model proposed by Turner and Turner (2011). The range of sizes of the apex angles can most likely be explained in terms of the directional spreading of waves approaching the surf zone.

More about this publication?
  • The Journal of Marine Research, one of the oldest journals in American marine science, publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. Biological studies involving coupling between ecological and physical processes are preferred over those that report systematics. The editors strive always to serve authors and readers in the academic oceanographic community by publishing papers vital to the marine research in the long and rich tradition of the Sears Foundation for Marine Research. We welcome you to the Journal of Marine Research.
