Title: | Upwelling in the Eastern Subtropical North Atlantic Ocean | Other Titles: | Afloramiento en el margen oriental del Atlántico Norte subtropical | Authors: | Pastor, María V. | Director: | Pelegrí Llopart, José Luis Palter, Jaime |
UNESCO Clasification: | 2510 Oceanografía | Keywords: | Áreas de afloramiento | Issue Date: | 2011 | Abstract: | Coastal upwelling in the eastern margin and offshore curl-driven upwelling in the southeastern margin, make the subtropical Northeast Atlantic a region of major primary productivity. When examining a broad zonal area, from the coast to 40_W, we find that the upward transport of nutrients due to offshore curl-driven upwelling becomes the main control on productivity. Nevertheless, despite its relatively small zonal extension of about 100 km, coastal upwelling extends its impact towards the open ocean through offshore Ekman transport and convergence of the meridional flow at Cape Blanc (21_N). El afloramiento costero en el margen este y el aforamiento por rotacional del viento, o bombeo de Ekman, en el margen sureste hacen de esta zona del Atlántico Norte subtropical una región de principal importancia por su alta productividad. Examinando una extensiva área, desde la costa hasta 40_O, encontramos que el transporte de nutrientes por bombeo de Ekman ejerce un control principal en la productividad. Por otro lado, aunque la escala zonal del afloramiento costero es de tan solo unos 100 km, su influencia se extiende hacia océano abierto gracias al transporte de Ekman y a la convergencia del flujo meridional en Cabo Blanco (21_N). |
