  abstract = {{A}long with their important diversity, coastal ecosystems receive various amounts of nutrients, principally arising from the continent and from the related human activities (mainly industrial and agricultural activities). {D}uring the 20th cen-tury, nutrients loads have increased following the increase of both the global population and need of services. {A}long-side, climate change including temperature increase or atmospheric circulation change has occurred. {T}hese processes, {E}cosystem state changes are hard to monitor and predict. {T}o study the long-term changes of nutrients concentrations in coastal ecosystems, eleven {F}rench coastal ecosystems were studied over 20 years as they encompass large climatic and land pressures, representative of temperate ecosystems, over a rather small geographical area. {B}oth univariate (time series decomposition) and multivariate (relationships between ecosystems and drivers) statistical analyses were used to determine ecosystem trajectories as well as typologies of ecosystem trajectories. {I}t appeared that most of the {F}rench coastal ecosystems exhibited trajectories towards a decrease in nutrients concentrations. {D}ifferences in trajec-tories mainly depended on continental and human influences, as well as on climatic regimes. {O}ne single ecosystem ex-hibited very different trajectories, the {A}rcachon {B}ay with an increase in nutrients concentrations. {E}cosystem trajectories based on ordination techniques were proven to be useful tools to monitor ecosystem changes. {T}his study highlighted the importance of local environments and the need to couple uni-and multi-ecosystem studies. {A}lthough the studied ecosystems were influenced by both local and large-scale climate, by anthropogenic activities loads, and that their trajectories were mostly similar based on their continental influence, non-negligible variations resulted from their internal functioning.},
