In the face of ongoing social and environmental crises, there is an urgent need to adapt our daily behaviors, educational approaches, and resource management strategies in response to a rapidly changing planet. The global efforts of the UN Decade of Ocean Science for Sustainable Development (Ocean Decade) have been defined as a pivotal collective action paving the way toward a transformative change. A diverse range of professionals and stakeholders are actively contributing to this mission, with several initiatives already evolving into long-term success stories. However, many regions and sectors still require significant progress to meet the Sustainable Development Goals (SDGs). This chapter highlights key contributions to the Ocean Literacy movement developed since the early stages of the Ocean Decade. It presents a selection of effective field-based experiences, and offers practical insights to support future Ocean Literacy initiatives. These examples aim to help individuals and organizations align their efforts with identified gaps and objectives, strengthening coherence and impact in the ongoing global endeavor to restore humanity’s relationship with the Ocean.
