Oceanography the flank sands of either side, probably a response to winnowing by wave surge. The inner shelf ridges themselves appear to be in a state of slow transit, wherever there is a bathymetric time series adequate to test this hypothesis (Figs. 35 and 36). The pattern of movement is a fairly consistent one, in which both shoreface-connected and isolated inner shelf ridges move along similar trajectories. Where the angle of convergence of the ridge crest with the shoreline is fairly large, the ridges are moving downcoast and offshore, extending their crestlines so as to maintain contact with the shoreface as they do so. Where the ridges are nearly coast-parallel, they are extending these crestlines downcoast, and may move either inshore or offshore, but more commonly offshore. The considerations just discussed strongly suggest that inner shelf ridges continue to interact with the shelf flow field after detachment, in such a way as to main- tain their morphologic and textural characteristics. In fact, ridged inner shelf topography occurs on sectors of the North American inner shelf where it cannot have 74-20 74° 10'. FIGURE 34.
