In this paper, a method to analyze historical surface drifter data is presented that is aimed at investigating particle evolution as a function of initial conditions. Maps of drifter concentration at different times are built and interpreted as maps

Because of the increase in the realism of ocean models and in the coverage of Lagrangian data sets in most of the worlds oceans, assimilation of Lagrangian data emerges as a natural avenue to improve ocean state forecast with many potential practic

The increasing realism of ocean circulation models is leading to an increasing use of Eulerian models as a basis to compute transport properties and to predict the fate of Lagrangian quantities. There exists, however, a significant gap between the sp

The Sicily Channel connects the western and eastern Mediterranean sub-basins, playing a fundamental role in the dynamics of the Mediterranean circulation. The flow in the Channel is driven by direct forcing such as wind and by thermohaline processes
