Abstract : A radiographic study was conducted on impregnated sand samples taken from beach cusps on Marina Beach, Monterey Bay, California, over a 7-month period from September 1970 to April 1971. The radiographs revealed much more structure than is discernable with the unaided eye in trenching or peeling. The microstructure found consisted of cross-lamination, rhythmic stratification, and distinct mineral layering. Migration of these cusps was studied by means of visual observations and time-lapse photography. Cyclic changes in the cusp profile were found to correspond with wave action and tidal influences. No simple relation between ocean action and cusp structure or development was evident. (Author) No simple relation between ocean action ajd cusp structure or development was evident. (Author)
