In order to study the storage of Cant in the Iberian Basin, variables of the carbonic system (i.e., pH, total inorganic carbon, and total alkalinity), among others, were measured during the CAIBOX cruise conducted between July and August 2009 within the framework of the CAIBEX project (Shelf-Ocean Exchanges in the Canary-Iberian Large Marine Ecosystem).

In order to study the storage of Cant in the Iberian Basin, variables of the carbonic system (i.e., pH, total inorganic carbon, and total alkalinity), among others, were measured during the CAIBOX cruise conducted between July and August 2009 within the framework of the CAIBEX project (Shelf-Ocean Exchanges in the Canary-Iberian Large Marine Ecosystem). The storage of Cant was estimated using two different back-calculation techniques (i.e., the φCºT and TrOCA methods) and for six layers of the water column corresponding to the approximate locations of the characteristic water masses of the region and the mixed layers. For the whole water column and for the year 2009 the Cant storage values determined by the φCºT and TrOCA methods were 88.1 ± 3.8 and 93.7 ± 3.7 molC m–2, respectively. Moreover, the Cant storage rate from 1993 to 2009 was also estimated considering data from three additional cruises (OACES 1993, CHAOS 1998, and OACES 2003). The Cant storage rates were 1.41 ± 0.25 and 1.67 ± 0.13 molC m–2 yr–1 with the φCºT and TrOCA methods, respectively. An increase in anthropogenic CO2 uptake by the ocean can be seen when compared with previous published results. Between the periods 1977–1997 and 1993–2009, the Cant concentration increased around 28–49% in the first 2000 m.
El sistema del carbono en las masas de agua de la Cuenca Ibérica (océano Atlántico norte) se ha visto afectado en las últimas dos décadas por el aumento de CO2 antropogénico (Cant). Durante la campaña CAIBOX (del proyecto Shelf-Ocean Exchanges in the Canary- Iberian Large Marine Ecosystem) y con el fin de estudiar el almacenamiento de Cant en la Cuenca Ibérica, se midieron entre julio y agosto de 2009, entre otras variables, las del sistema del carbónico [pH, carbono inorgánico total (CT) y alcalinidad total (AT)]. El almacenamiento de Cant fue estimado usando dos técnicas de retrocálculo diferentes (métodos φCºT y TrOCA) y en seis capas de la columna de agua, correspondientes unas a la ubicación aproximada de las masas de agua típicas de la región y otras a las capas de mezcla de las masas de agua. El almacenamiento de Cant en la columna de agua completa para 2009 fue de 88.1 ± 3.8 molC m–2 según el método φCºT y de 93.7 ± 3.7 molC m–2 según el método TrOCA. Por otra parte, se estimó también la tasa de almacenamiento de Cant desde 1993 a 2009, teniendo en cuenta los datos de tres campañas adicionales (OACES 1993, CHAOS 1998 y OACES 2003). Las tasas de almacenamiento de Cant obtenidas fueron 1.41 ± 0.25 y 1.67 ± 0.13 molC m–2 año–1 según los métodos φCºT y TrOCA, respectivamente, lo que al compararse con estudios previos representa un incremento en la captación de CO2 antropogénico, ya que entre los periodos 1977–1997 y 1993–2009, la concentración de Cant se aumentó en torno a un 28–49 % en los primeros 2000 m de profundidad. |
