Building and improving existing coastal monitoring capabilities and developing innovative coastal products is vital to coastal protection in the face of climate change. Through new coastal observations (satellite and land-based remote sensing data in addition to in situ observational data), advanced hydrology models, coastal models, and unified coastal management systems, coastal protection and forecasting are improved. With the advances in technological progress, it is possible to also implement new approaches with numerical models and Artificial Intelligence (AI) methods, enabling pan-European scale methods. This session focuses on advanced, seamless ocean monitoring and forecasting, from global/regional systems to coastal systems, through demonstrations of new products and improved co-produced services. These services aim to provide the marine knowledge needed for coastal applications addressing environmental and social challenges and those enhanced by climate change, such as: pollution hazard/risk mapping, coastal erosion, resource management, harmful algal blooms, and combating ecosystem degradation, supporting Marine Protected Areas, and addressing natural hazards and extreme events.
