The United Nations Decade of Ocean Science for Sustainable Development, 2021-2030 is a unique ten-year, global cooperative program to expand scientific partnerships to support effective science, ocean management, and sustainable development. National and international experts will be invited to engage the AMS members to learn their science priorities and identify opportunities to become involved in the implementation planning process. The Decade will consist of initiatives to map the ocean floor and processes, bolster ocean observation systems in all basins, develop a data and information portal, establish an integrated multi-hazard warning system, advance ocean component in earth-system observation, research and production, and strengthen capacities, ocean literacy and technology cooperation.  The Implementation Plan (to be finalized 2020) will seek to achieve additional specific results, driven by the mission needs of society and science, and produce lasting benefits. Members of the Decade Executive Planning Group will solicit AMS input to inform the plans.
