We investigate the transport properties of monopolar coherent vortices in Rossby wave barotropic turbulence, exploring the role of a finite Rossby deformation radius. Isolated monopoles can trap tracers releasing them at a different latitude and sufficiently strong free-surface effects can inhibit Rossby waves emission by the vortices. In environments with a finite Rossby deformation radius, as in the ocean, coherent structures can survive for very long time even in the presence of strong differential rotation, without releasing what is trapped in their interior.
