On November 27, 2023, the United Nations Decade of Ocean Science for Sustainable Development （Ocean Decade） Ocean and Climate Nexus Community of Practice （COP）， hosted by DCC-OCC, held the launching meeting online. Participants, endorsed representatives of the United Nations Ocean Decade actions, included over thirty domestic and international experts and scholars, such as Prof. Aileen Tan Shau Hwai （Vice Chairperson of IOC/WESTPAC）， Prof. Zacharie SOHOU （Institute of Fisheries and Oceanographic Research of Benin）， Prof. Tsuyoshi Sasaki （Asia Marine Educators Association）， Prof. Kenny Leung （Global Estuaries Monitoring, GEM）， Eoghan Griffin （Scientific Committee on Antarctic Research and Decade Collaborative Centre for the Southern Ocean Region, DCC-SOR）， and Steven Bograd （Sustainability, Predictability, and Resilience of Marine Ecosystems, SUPREME）。 The meeting aimed to leverage the role of the COP within the Ocean Decade, fostering collaboration, implementation, and co-design of actions in the field of ocean and climate.

Professor Yu Weidong, the Scientific Executive of DCC-OCC, emphasized the importance of collaboration and encouraged participants to share their ideas to collectively drive innovation in ocean science during the opening remark. Subsequently, Emma Needham from UNESCO/IOC provided a brief overview of the latest developments in the Ocean Decade and outlined the role and operational methods of the Ocean Decade's Community of Practice. Dr. Guan Song, the Senior Program Officer of the center, presented the core functions, progress, and planning of the center. In the discussion session, participants introduced their respective actions within the Ocean Decade, expressed their needs and expectations for the Ocean and Climate Nexus COP, and shared their perspectives on maximizing the COP's effectiveness. DCC-OCC representatives addressed questions from participants and conveyed a positive attitude towards collaboration.

The United Nations Oceans Decade COP is a voluntary group of Oceans Decade actions aimed at facilitating networking, cooperation and exchange ideas to fulfill the objectives of the Oceans Decade. The Oceans and Climate Nexus COP is one of these communities of practice that focuses on ocean-climate and is hosted and led by DCC-OCC. It is a place where Oceans Decade-related initiatives and multi-stakeholders can easily communicate and interact, stimulate innovation and collaboration, and promote the outcomes of the Ocean Decade. In the future, the Oceans and Climate Nexus COP will convene quarterly network meetings to make full use of the platform.
