Located on the Mediterranean coast of Morocco, the Al Hoceima Marine Protected Area is a refuge of a variety of ecosystems, providing a unique lens through which to investigate the intricate connection between water quality and coastal resilience in the face of mounting climate change challenges. This study examined the complex interactions that exist between the severe effects of climate change on coastal ecosystems and water quality, using the Al Hoceima MPA as a test case to comprehend and resolve these issues. Using data collected as part of the Odyssea project, this research focuses on crucial parameters such as temperature, conductivity, chlorophyll concentration and micro-plastic pollution levels. The specialized Glider sensors used on Odyssea missions in the Alboran Sea provide real-time, high-resolution data, which form the cornerstone of our study. These sensors, equipped with advanced technology, monitor changes in ocean conditions, water clarity, sedimentation levels and marine ecosystem health, which is crucial to understanding the complex link between water quality and ecological resilience. The methodology integrates these data into complex models that not only visualize the current state of MPA water quality but also forecast its response to climate change variables. Temperature increases and affects ocean conditions are closely examined to provide the basis for informed decision-making and recommendations for effective management and conservation of the Al Hoceima MPA. Our findings indicate significant variations in chlorophyll concentrations and microplastic levels, particularly in Cycle 2, which suggest localized pollution impacts. Temperature trends also varied, highlighting areas of potential anthropogenic influence. This work clarifies the precise relationship between resilience and water quality in a marine protected area, which significantly advances the conversation about adapting to climate change. By figuring out the intricate mechanisms at work in the Al Hoceima MPA, this study provides useful insights into how effective water quality management can strengthen the capacity of the MPA to respond to the challenges posed by climate change. As the international community strives to safeguard critical ecosystems, Al Hoceima marine protected area emerges not only as a geographical focal point but also as a paradigmatic example, illustrating the delicate interdependence of water quality and ecological resilience in the face of climate change.
