The Madeira Coastal Insight Service (MCIS) is designed to enhance the monitoring of coastal waters and improve environmental management in Madeira Island, an outermost region of the European Union (EU). By integrating high-resolution numerical models, remote sensing data, and in-situ observations, MCIS contributes to the implementation of several EU policies and directives, including the Water Framework Directive, the Marine Strategy Framework Directive, the Urban Waste Water Treatment Directive, the Bathing Water Directive, and the Nitrates Directive. The service focuses on two primary Use Cases: (1) assessing water quality, with a focus on sanitary risks to support tourism and aquaculture activities, and (2) evaluating nutrient budgets to mitigate the impacts on marine ecosystems. Through real-time monitoring, MCIS strengthens decision-making capabilities, improves pollution prediction, and ensures compliance with EU environmental standards. This paper outlines the MCIS project, detailing its objectives, components, and preliminary results from both Use Cases, while highlighting its alignment with EU policies and directives. Expected outcomes include enhanced local environmental management, strengthened policy implementation capacity, and actionable insights for sustainable coastal protection in Madeira Island.
