Statistical analysis of turbulent dispersion in the sea surface layer based on satellite-tracked drifter data
This paper deals with the analysis of drifter campaigns realized in two different domains, the Gulf of Mexico and the Mar Grande Basin (Italy). Relative dispersion, diffusivity, and velocity variance were estimated, identifying different growth regimes. An exponential growth of the dispersion process was detected during the initial phase of deployment, and empirical laws for horizontal diffusivity were inferred.
