  abstract = {{T}he proliferation of {S}argassum in the {T}ropical {A}tlantic has occurred almost every year since 2011, but a strong variability of biomass is observed among years. {E}ssential knowledge about the drivers of {S}argassum growth and decay is still lacking to explain this interannual variability. {B}enefiting from accurate basin scale {S}argassum detections provided by remote sensing, and from physical and biogeochemical ocean simulations, we developed a {L}agrangian drift-growth model to simulate {S}argassum distribution over the period 2016-2020. {T}he resulting trajectories and biomass time series of {S}argassum aggregates were analyzed to highlight the main limiting factors of growth and decay. {T}he nitrogen and phosphorous concentrations are found to be weakly restrictive compared to physical limiting factors, especially the temperature. {I}n particular, the warm waters found off northern {B}razil appear to be instrumental in triggering the end of seasonal growth of {S}argassum. {T}he timing of the seasonal warming of this region strongly impacts the quantities of {S}argassum simulated each year. {T}his suggests that this region should be monitored to anticipate the development of {S}argassum and resulting strandings.},
