Abstract
IN the open shelf seas of north-west Europe there are large areas where the sand floor has been wrought into ridges lying approximately normal to the paths of the strongest tidal currents1. In the southern part of the North Sea, for example, these sand waves are on average about 300 yards apart and about 15 ft. high, though very variable in dimensions. The asymmetry of their cross-sectional profile suggests that they are moved forward by removal of material from the gentle slope for deposition on the steeper lee slope. Thus, it is fair to assume that current-bedding is being made in the open sea just as it can be observed to be made in the shallow waters of an estuary or in a flume.
