We consider inertial (i.e., finite-size and buoyancy) effects on the motion of particles advected by ocean velocities derived using satellite altimetry measurements. We find that cyclonic/anticyclonic coherent material eddies attract (repel) light/heavy finite-size particles in the northern (southern) hemisphere. Observational evidence (from the analysis of surface and subsurface drifting buoy trajectories, and distributions of macroscopic algae) so far collected provide support for our theoretical results. |
