Carriers of<i>Sargassum</i>and mechanism for coastal inundation in the Caribbean Sea

We identify effective carriers of Sargassum in the Caribbean Sea and describe a mechanism for coastal choking. Revealed from satellite altimetry, are mesoscale eddies (vortices 50-km radius or larger) with coherent material (i.e., fluid) boundaries. These observer-independent—unlike eddy boundaries identified instantaneously closed streamlines altimetric sea-surface height field—and furthermore harbor finite-time attractors networks elastically connected finite-size buoyant “inertial” particles dragged by ocean currents winds, mathematical abstraction rafts. The inundation, using minimal model surface-intensified eddies, is thermal instability presence bottom topography.
