Description
Summary:LONG-TERM GOALS. To understand and parameterize small-scale ocean processes. To understand ocean tides and their effects. To understand surface wave processes. OBJECTIVES. To elucidate and quantify the back effect on internal waves, and other motions, of refracted and breaking surface waves. To understand ocean tides and to quantify the power available from exploitation of strong tidal currents. To understand aspects of extreme and unexpected surface waves. APPROACH. Recent studies have been largely analytical, with support from numerical evaluation. WORK COMPLETED. Progress has been made in adding dissipation to studies of the interaction between surface waves and currents. The reason for the extreme tide of Ungava Bay has been discovered. General results on the maximum power obtainable from tidal currents have been derived. A review of extreme events has been completed. The frequency of occurrence of unexpectedly large surface waves has been evaluated.
