            <gco:CharacterString>Le projet ECO – évolution de l'augmentation du CO2 – a été planifié et développé pour agrandir la banque de données de mesures de fugacité fCO2 dans le golfe de Gascogne.

Les mesures ont été prises à bord de navires d'opportunité, le long de la route commerciale entre Vigo en Espagne et Saint-Nazaire en France, entre décembre 2002 et décembre 2004. 

En outre les principaux paramètres physiques et biologiques ont été suivis pour évaluer leur pertinence dans la variabilité de CO2 à l'échelle saisonnière et interannuelle. Les mesures ont été effectuées le long de 150 trajets. Le but de ce travail est de contraindre l'évaluation des flux de CO2 ainsi que de décrire le rôle des différents facteurs de la distribution fCO2 au cours des campagnes ECO.</gco:CharacterString>
