| The worldwide decline of seagrass meadows may result in the loss of relevant ecosystem services such as the carbon sequestration within marine ecosystems. In this paper, net primary production (NPP) of Zostera noltei meadows was assessed in the Arcachon Bay (SW France) with the aim of understanding the impact of meadows decline on C sequestration capacity at a basin scale. Net growth rates obtained by means of a year-long leaf-marking experiment (2005-2006) were coupled to interannual biomass measurements (1983-2010) to obtain a direct estimate of NPP. Concurrently, an indirect estimate was obtained through a mathematical model which embedded natural factors variation (temperature, light and nutrients).
