  abstract = {{C}oastal marine ecosystems ensure fundamental hydro-ecological functions and support high levels of biodiversity, besides being an important resource for local populations. {T}hese biocenosis have been increasingly threatened by human pressures (e.g. pollution, overfishing) along with climate change, which may have a dramatic impact on them. {T}he {N}ational {P}ark of {B}anc d'{A}rguin ({PNBA}) in {M}auritania, one of the biggest parks in {W}estern {A}frica, is a {RAMSAR} zone (classified by {UNESCO} since 1989) that plays a major role in (i) the maintenance of marine biocenosis, (ii) the protection of the ecosystems and (iii) the sequestration of carbon dioxide. {E}cosystem databases and associated maps of the {PNBA} are out of date and limited to the southern and central parts of the park: updating is thus needed. {I}n this paper, a supervised {S}upport {V}ector {M}achine ({SVM}) was deployed using high-resolution images from {S}entinel-2 combined with field data to map marine biocenosis of the {PNBA}. {T}he results highlight that {S}entinel-2 shows good classification accuracy for mapping marine biocenosis (>80% overall accuracy and a kappa index of 0.75), including seagrass beds. {A}lso, the use of high-resolution sensors like {SPOT}-6 (1.5 m pixels) can overcome the limitations of {S}entinel-2 (10 m pixels) when it comes to detecting small ecosystems distributed in patches. {T}he use of freely-downloadable {S}entinel-2 data, processed using geoinformatic freeware, make the methodology reproducible, affordable and easily transferable to local actors of biodiversity conservation for long term usage.},
