A dataset of Zostera marina and Zostera noltei structure and functioning in four sites along the French coast over a period of 18 months. SEANOE. https://doi.org/10.17882/97962 In addition to properly cite this dataset, it would be appreciated that the following work(s) be cited too, when using this dataset in a publication : Lacoste Elise, Desroy Nicolas, Blanchet-Aurigny Aline, Bernard Guillaume, Bajjouk Touria, de Casamajor Marie-Noelle, Cimiterra Nicolas, Curd Amelia, Derrien Lauriane, Dubois Stanislas, Foucault Elodie, Messiaen Gregory, Rigouin Loic, Soissons Laura, Tancray Aurelien, Ouisse Vincent (2026). The dynamic nature of carbon and oxygen benthic fluxes in seagrass habitats. Peer Community Journal, 6, e3 (21p.). . https://doi.org/10.24072/pcjournal.662 The data concerns the structure and morphometry of the seagrasses Zostera marina and Zostera noltei, the diversity of the associated epifauna and the benthic fluxes of oxygen, carbon and nutrients. The dataset includes 103 sampling events divided among four sites and spread across three distinct marine biogeographic regions (i.e. the English Channel, Bay of Biscay and Western Mediterranean), and up to five seasons, depending on the site. The sampling scale allows inter-site and intra-habitat comparisons . Environmental conditions are also described at the site scale. As the most comprehensive and broadscale French dataset on seagrass structure and functioning  to date, it is useful for both data analysis and management actions. This study is part of the Life MarHa project funded by the European Union.
