The EU-funded AtlantECO project aims to develop and apply a novel, unifying framework that provides knowledge-based resources for a better understanding and management of the Atlantic Ocean and its ecosystem services. AtlantECO will engage with citizens and actors from the industry and policy sectors in order to stimulate responsible behaviour and Blue Growth. The project focuses on three pillars of research: microbiomes, plastic and the plastisphere, and seascape connectivity. In pursuit of this goal, AtlantECO is bringing together experts and pioneers from Europe, South America and South Africa with the relevant resources, knowledge and experience.
