“…This interpretation is possible when considering the general hydrological and plankton dynamics of the Bay. The seasonal phytoplankton development is the same seaward of the Loire and the Gironde river plumes, with a late winter bloom of diatoms followed by a short spring bloom and then a dominance of small phytoplankton (Labry et al, 2001;Gohin et al, 2003Gohin et al, , 2005Loyer et al, 2006). These seasonal cycles are not synchronized between the south and the north parts of the Bay, as the south develops a thermal stratification before the north (Koutsikopoulos et al, 1998;Castaing et al, 1999;Puillat et al, 2004).…”

“…They considerably reduce the amount of nutrients available within the surface layer. Phosphate limitation is enhanced by an excess of nitrate in the runoff of the Loire and Gironde rivers (Labry et al, 2002;Loyer et al, 2006) and tends to result in a dominance of small-sized cells in spring due to their high competitiveness in such an environment (Legendre and Rassoulzadegan, 1995). Consequently, spring represents a change from the diatom-dominated winter community (Herbland et al, 1998) to the dominance of small phytoplankton cells.…”

“…between two consecutive springs), can be directly related to spatial and year-to-year variations in water temperature and salinity (Villate et al 1997, Zarauz et al 2007). Moreover, in the Bay of Biscay, the plumes of the Gironde and the Loire Rivers considerably influence the hydrological structure and the primary production on the continental shelf, all along the year (Planque et al 2004;Puillat et al 2004Puillat et al , 2006Loyer et al 2006;. Slope currents occurring on the shelf break (Koutsikopoulos and Le Cann 1996) can also favour primary production in these waters due to nutrients inputs (e.g.…”

“…En numerosos artículos bien con imágenes satelitales (Barale et al, 2005;Wall et al, 2008) o bien con el estudio mediante muestreos de una zona costera Henriquez et al, 2006;Loyer et al, 2006) se observa como la distribución y el gradiente de la mancha eutrófica es muy variable en función de la zona de estudio. Por tanto la distribución de la red de muestreo debe estar condicionada por la extensión de la zona de eutrofia.…”

“…Un estudio realizado por Barale et al (2005) con imágenes satelitales de la distribución de la clorofila a, muestran como para el Mar Adriático oeste la extensión alcanzada por la influencia continental en la mancha de clorofila a y su gradiente son drásticamente diferentes a la costa este. En otras condiciones, como son los mares sujetos a afloramientos, se ve roto este gradiente en el comportamiento de la clorofila a debido a los cambios en la estructura termal de la columna de agua, como podemos observar en los estudios llevados a cabo por Loyer et al (2006) Estos estudios mencionados nos indican que cada ecosistema es único, y que se necesita un buen conocimiento del modelo conceptual del funcionamiento del sistema en cada área para poder aplicar una red de muestreo que nos asegure una calificación fiable del estado ecológico. Es decir, en el diseño del muestreo hay que considerar todos los factores que dan lugar a los procesos de eutrofia y el funcionamiento temporal y espacial del sistema, para que se pueda valorar adecuadamente el estado trófico de un ecosistema litoral (Gilbert et al, 2006).…”
