Fecha de publicación: | 2008 | Editor/a: | 0094-8276 | Publicación seriada: | Geophysical Research Letters | Resumen: | This work illustrates the great potential of multichannel seismic reflection data to extract information from the finestructure of meddies with exceptional lateral resolution (10–15 m). We present seismic images of three meddies acquired in the Gulf of Cadiz (SW Iberian Peninsula), which consist of concentric reflectors forming oval shapes that sharply contrast with the background oceanic structure. The seismic images reveal the presence of different regions within the meddies that are consistent with those observed in historical temperature (T) and salinity (S) data. The core region, characterized by smooth T and S variations, is weakly reflective. The double‐diffusive upper and lower boundaries and the lateral‐interleaving outer edges, characterized by stronger T and S contrasts, display strong reflectivity bands. These new observations clearly show differences between layers developed at the upper and lower boundaries that can contribute to the knowledge of mixing processes and layering formation in oceans. | URI: | http://hdl.handle.net/10553/49052 | ISSN: | 0094-8276 | DOI: | 10.1029/2008GL033971 | Fuente: | Geophysical Research Letters [ISSN 0094-8276], v. 35 (L11609) |
