Vertical Mixing and Horizontal Transport in Stratified Flow at a Near Coastal Site
Abstract
Frequent stratification (and restratification) episodes, strong along-shore tidal flows and variable local bathymetry characterize near coastal environments. These features are thought to control vertical mixing and horizontal transport in such near shore regions. To better understand this environment, a dye-dispersion study was performed in an area off San Clemente Island, CA-in March 1999, along with detailed measurements of the flow and vertical mixing. The major result of this work is that observed horizontal dispersion rates of towed fluorometer data are about 2 orders of magnitude larger than generally accepted values. Even when scale dependant dispersion (Stacey et. al, 2000) is applied to the problem, the coefficient of the dispersion term are 0.08 cm(exp 2/3)/s, substantially larger than observed values.
