We propose a characterization of fluid particle dynamics in the unsteady Double-Gyre system using topological time series analysis through homologies. Streaklines evidence that fluid particle sets remain persistentlyclustered during advection in this flow. The particles belonging to the clusters exhibit distinctive dynamical properties. In the background, particle trajectories present an underlying topological structure that iscompatible with a stretching and folding such as are present in the suspension of a Smale Horseshoe map.
