The ocean's significance encompasses crucial ecosystem services including climate regulation, oxygen production and food supply. The ocean is also a major player in the global economy. However, human activities continue to harm the ocean, jeopardising these vital functions. In July 2022, the United Nations Ocean Conference adopted a political declaration entitled "Our ocean, our future, our responsibility," emphasising the need for sustainable ocean management and protection. However, an important initial question arises: who are the “Our”? or, rephrased “Whose ocean” is it? This study presents first answers to this question, based on interviews with ocean professionals from diverse backgrounds. Their responses showcased the complexity of the issue, with differing opinions on ocean “ownership” and “control”. Despite the diversity of perspectives, a shared emphasis emerged: shifting from profit-driven decision-making to prioritising marine ecosystem health. Proposed approaches to build a sustainable relationship between people and the ocean include promoting ocean literacy and marine research and ensuring global accountability. These voices offered valuable insights towards ocean sustainability, guiding future academic, educational and policy-making efforts.
