This report aims to present the implementation methods of each Mission Ocean and Waters LightHouse CSA (BlueMissionBANOS, BlueMissionAA, BlueMissionMed, EcoDaLLi) within their respective areas, as well as the implementation of the overarching CSA (Prep4Blue). We will also discuss the role of these CSAs in connecting Mission Ocean and Waters funded projects, enhancing synergies, and highlight some of their key activities. Throughout this report, we will explore the position and interactions of each CSA within the Mission Ocean and Waters project ecosystem, as well as their collaboration with the Mission Implementation Platform (MIP Ocean) and the Mission Secretariat. Another section will focus on the results achieved by each CSA, particularly those that will be transferred as legacy to the broader Mission ecosystem. We will also address the barriers and challenges faced by the CSAs, along with their recommendations. Finally, we will discuss how the LH CSAs envision their role in the second phase of the Mission (2026-2030), offering key recommendations and suggested actions for improvement.
