Abstract
A data record of 16 hour of highly resolved concentration profiles and velocities was collected near Hamilton Harbor, Lake Ontario. The data record covered periods of calm currents, wave buildup, and flow reversal. Pattern recognition techniques were applied to determine the spatial structure and frequency of occurrence of the ten-minute boundary layer average profiles. Using a shape similarity analysis, the 96 average concentration profiles in the 16 hour record collapsed to only two pattern classes. The first class associates with steady currents and moderate waves, and the second class associates with high intensity of current induced turbulence and well developed wave activity. The pattern shapes extracted by the shape and magnitude analysis in the 16 hour record are slowly evolving from a linear-log distribution in the current flow period to log-linear distribution during steady current and wave buildup, and then to log-log distribution when current induced turbulence and well developed wave activity are in command.
