| Summary: | 16 páginas, 4 figuras, 3 tablas [EN] As part of the VACLAN (Climatic Variability in the North Atlantic) project a section covering the Bay of Biscay was sampled on board R/V Thalassa in September 2005. This work estimates the distribution of the different water masses using an extended optimum multiparametric method and it studies water mass distribution of anthropogenic carbon as calculated with two different approaches. Regarding water masses present in this region, the Eastern North Atlantic Central Water layer is mainly constituted by its subpolar component and the Mediterranean Water appears very diluted, increasing its dilution towards Northeast. In relation to the anthropogenic carbon inventory there are small differences between two different methods used, 95 vs 87 mol C m-2, both with the same distribution pattern where the concentration decreases with the depth. Eastern North Atlantic Central Water presents the highest anthropogenic carbon inventory, supporting more than 50% of the total column (52%). This work confirms the relevant role of the Bay of Biscay as a sink zone in the oceanic circulation. [ES] En septiembre de 2005, a bordo del B/O Thalassa y como parte del proyecto VACLAN (Variabilidad CLimática en el Atlántico Norte) se muestreó una sección atravesando el Golfo de Vizcaya. Este trabajo estima la distribución de las diferentes masas de agua usando un método óptimo multiparamétrico extendido y estudia la distribución de carbono antropogénico en las mismas calculado usando dos métodos distintos. Con respecto a las masas de agua presentes en la región, la capa de Agua Central del Este del Atlántico Norte está principalmente constituida por su componente subpolar y el agua Mediterránea aparece muy diluida, aumentando su dilución hacia el Noreste. En relación al inventario de carbono antropogénico hay pequeñas diferencias entre los dos métodos utilizados, 95 vs 87 mol C m-2, aunque en ambos se observa el mismo patrón de distribución vertical, la concentración decrece con la profundidad.
