Abstract
An investigation of the horizontal turbulent diffusion in relation to environmental conditions, such as density stratification, vertical current shear, and current variability, is presented. Tracer experiments have been conducted in fjords, in coastal areas, and in offshore waters with a view to obtaining data for such a study. In addition, observations of wind velocity, salinity, temperature, and current have been carried out. A model is proposed assuming that the apparent horizontal diffusion is determined by the combined action of vertical diffusion and vertical current shear. The theoretical predictions are found to compare well with the experimental results. DOI: 10.1111/j.2153-3490.1972.tb01529.xKeywords
