This contribution serves as a perspective piece that helps to illuminate and situate the chapters across this three-volume publication in relation to one of the Ocean Decade’s primary objectives—to connect people and the Ocean. Along with providing a high-level summary of the Ocean Decade Challenge 10 White Paper that was developed through the Ocean Decade Vision 2030 process, this perspective piece explores how the White Paper recommendations can be put into action using a theory of change framework. Challenge 10 focuses on restoring society’s relationship with the Ocean by addressing the human behaviors that drive Ocean threats and positioning Ocean Literacy as a key societal outcome. Emphasizing the need for interdisciplinary collaboration and inclusive engagement across sectors, a working theory of change is proposed, structured around four key drivers—Knowledge Systems, Communications, Education, and Cultural Connections—each contributing to a shift in how people value and interact with the Ocean. By outlining a practical foundation for advancing Ocean-positive behaviours, this perspective piece aims to provide a useful lens to apply and help connect the tangible initiatives captured in this important and timely publication. Collectively, these initiatives are helping to create the conditions and opportunities to help inspire and build an Ocean-literate society.
