Título: | Influence of the North Atlantic Oscillation on Mediterranean deep-sea shrimp landings |
Autor: | Maynou, Francesc CSIC ORCID | Palabras clave: | Aristeus antennatus North Atlantic Oscillation Deep-sea Benthic-pelagic coupling NAO |
Fecha de publicación: | 24-jun-2008 | Editor: | Inter Research | Citación: | Climate Research 36(3): 253-257 (2008) | Resumen: | Recent studies have shown that the population dynamics of deep-sea organisms are affected by coupling between surface oceanic processes and energy, or trophic resources, reaching the sea floor. I analysed the correlation between the landings of a deep-sea shrimp (Aristeus antennatus) in Catalonia (NW Mediterranean) and the climatic indices of the annual North Atlantic Oscillation (NAO) and winter NAO between 1971 and 2007. I show that the size of landings is significantly correlated with the NAO and with the winter NAO, with 2 and 3 yr lags in both cases. Considering that around 60% of the landings comprise 2 to 3 yr old females, my results suggest that climatic conditions over the western Mediterranean (especially in winter) influence the year-class strength of this deep-sea shrimp, fished from 600 to 800 m depth. | Descripción: | 5 pages, 3 figures. | Versión del editor: | https://doi.org/10.3354/cr00746 | URI: | http://hdl.handle.net/10261/17282 | DOI: | 10.3354/cr00746 | ISSN: | 0936-577X | E-ISSN: | 1616-1572 |
