In 2025, we will reach the halfway point of the UN Ocean Decade, and the year’s agenda of ocean events matches the global community’s rising ambition and action. There are now only five years left for the global ocean community to meet the Decade’s ambitious 2030 challenges. Against this backdrop, dozens of 2025 events provide spaces for experts, practitioners, and policymakers to convene and develop solutions to the most critical ocean sustainability challenges.
That’s why this year, Our Shared Seas is returning with our Blue Wave of Action series to highlight important ocean events of 2025, handpicked by the OSS team. The calendar is so full of high-profile events that we have split our Wave of Action into two publications! This edition covers the first six months of 2025.
