Fecha de publicación: | 2012 | Editor: | Universidad de Valparaíso | Citación: | Revista de Biología Marina y Oceanografía 47(3): 587-592 (2012) | Resumen: | Six bimonthly surveys during 2007 were carried out in Magdalena Bay (Mexico) during spring tide conditions. Spatiotemporal variations of temperature, salinity, nitrite, nitrate, ammonium, phosphate and chlorophyll-a were analyzed in the Bay. During spring-early summer (April-June) seawaters were colder and richer in new nutrients and chlorophyll-a than autumn and winter (February and October-December). The coastal upwelling during spring-early summer contributes with new nutrients to the Bay, whereas bottom-recycled nutrients should be the main input during the autumn-winter period. Thus, nutrients availability, dissolved inorganic nitrogen and phosphate, promote a seasonal pattern of phytoplankton biomass in Magdalena Bay. | Descripción: | 6 páginas, 3 figuras | Versión del editor: | http://www.revbiolmar.cl/resumenes/v473/473-587.pdf | URI: | http://hdl.handle.net/10261/65823 | ISSN: | 0717-3326 | E-ISSN: | 0718-1957 |
