Fluctuations in geopotential anomaly at eight 12-hr time-series stations off Washington appeared to result from semi-daily internal tides propagating seaward from the shelf break. Comparison of the observations with computations suggests the existence of a first mode wave. The oscillations did not appreciably decay offshore, perhaps as a result of bathymetric focusing.
