<jats:title>Significance</jats:title>
<jats:p>The detection of vortices in geophysical flows is important because of their role in global circulation and transport. The recent theory of elliptic Lagrangian coherent structures has shown that long-lived, coherent material eddies exhibiting no filamentation can be extracted from altimetry-derived surface velocities associated with slow, mesoscale motions in the ocean. Since similarly perfect eddies may not be expected to exist in the presence of faster, submesoscale motions, it has remained unclear whether persistent and materially coherent eddies can in fact be identified objectively even in highly resolved ocean data. Here we show that under a suitable extension of the notion of material coherence, coherent eddies at the mesoscale and submesoscale level can indeed be simultaneously detected from multiscale velocity data.</jats:p> |
