Over 70% of Chilean territory is in the ocean. Such an extension added to natural dynamics of water bodies are a great challenger when it comes to quantify and monitor their condition. Additionally, the sustainability of this natural resource is key to both, economic activities and protection of aquatic biodiversity. The pressure over oceanic and inland water bodies has increased due to a rise in drought periods, urbanization and deforestation, among other variables. Remote sensing data and tools, as well as machine learning methods and complex multivariable models, are being currently analyzed for suitable aquatic natural resources monitoring.
