Ausin, Blanca; Zuniga, Diana; Flores, Jose A.; Cavaleiro, Catarina; Frojan, Maria; Villacieros-Robineau, Nicolas; Alonso-Perez, Fernando; Arbones, BelenA systematic investigation of the spatial and temporal variability in coccolithophore abundance and distribution through the water column of the NW Iberian coastal up-welling system was performed. From July 2011 to June 2012, monthly sampling at various water depths was conducted at two parallel stations located at 42 degrees N. Total coccosphere abundance was higher at the outer-shelf station, where warmer, nu...
Diatoms as a paleoproductivity proxy in the NW Iberian coastal upwelling system...
Zuniga, Diana; Santos, Célia; Frojan, Maria; Salgueiro, Emilia; Rufino, Marta; De la Granda, Francisco; Figueiras, Francisco G.; Castro, Carmen G.The objective of the current work is to improve our understanding of how water column diatom's abundance and assemblage composition is seasonally transferred from the photic zone to seafloor sediments. To address this, we used a dataset derived from water column, sediment trap and surface sediment samples recovered in the NW Iberian coastal upwelling system. Diatom fluxes (2.2 (+/- 5.6) 10(6) valves m(-2) d(-1)...
