Concern with the impact of human activies on the coastal region of the world!s oceans has elicited interest in the so-called!!coastal boundary layerll-that band of water adjacent to the coast where ocean currents adjust to the presence of a boundary. Within this zone, roughly 10 km wide, several physical processes appear to be important. One of these, the tides, is of particular interest because their deterministic nature allOV1S unusually thorough analysis from short time series, and because they tend to obscure the other processes.. The Coastal Boundary Layer Transect (COBOLT) experiment was conducted within 12 km of the south shore of Long Island, New York to elucidate the characteristics of the coastal boundary layer in the Middle Atlantic Bight. Analysis of data from this experiment shows that 35 % of the kinetic energy of currents averaged over the 30 m depth are due to the semidiurnal and diurnal tides
