The data used came from the FAO and gaps in data were modeled using a linear regression between pesticides and fertilizers or agricultural GDP. Dasymetric maps were then used to distribute fertilizer data over the landscape using 2009 data from the Moderate Resolution Imaging Spectroradiometer (MODIS) at ~500 m resolution and aggregated to watersheds. Diffusive plume models from each watershed pourpoint (e.g. river mouths) were then used to model the distribution and intensity of organic pollution in coastal and marine environments.\n\nIt is possible to consult the scientific report of the **eDrivers** project: [**Characterizing Exposure to and Sharing Knowledge of Drivers of Environmental Change in the St. Lawrence System in Canada**](https://www.frontiersin.org/articles/10.3389/fmars.2020.00383/full) and the [**additional data**](https://www.frontiersin.org/articles/10.3389/fmars.2020.00383/full#supplementary-material).

Les données utilisées provenaient de la FAO et les lacunes dans les données ont été modélisées à l'aide d'une régression linéaire entre les pesticides et les engrais ou le PIB agricole. Des cartes dasymétriques ont ensuite été utilisées pour distribuer les données sur les engrais dans le paysage à l'aide des données de 2009 du spectroradiomètre imageur à résolution modérée (MODIS), à une résolution d'environ 500 m et agrégées aux bassins versants. Des modèles de panaches diffusifs pour chaque point d'écoulement des bassins versants (par exemple, embouchures de rivières) ont ensuite été utilisés pour modéliser la distribution et l'intensité de la pollution organique dans les environnements côtiers et marins.\n\nIl est possible de consulter le rapport scientifique du projet ***eDrivers*** : [***Characterizing Exposure to and Sharing Knowledge of Drivers of Environmental Change in the St. Lawrence System in Canada***](https://www.frontiersin.org/articles/10.3389/fmars.2020.00383/full) et les [**données complémentaires**](https://www.frontiersin.org/articles/10.3389/fmars.2020.00383/full#supplementary-material).
