On June 3, 2021, the Intergovernmental Oceanographic Commission (IOC) of the United Nations Educational, Scientific and Cultural Organization (UNESCO) announced the first official actions of the United Nations Decade of Ocean Science for Sustainable Development (2021-2030) (hereinafter referred to as "the Decade").

In 2017, the 72nd session of the General Assembly of the United Nations adopted a resolution declaring 2021-2030 as the "Decade of Ocean Science for Sustainable Development", and authorized the Intergovernmental Oceanographic Commission (IOC) of United Nations Educational, Scientific and Cultural Organization (UNESCO) to take the lead in formulating the implementation plan. In 2020, the 75th session of the General Assembly of the United Nations deliberated and adopted the Implementation Plan of the Decade. The Decade was officially launched in January 2021. The vision of the Decade is to build "The Science We Need For The Ocean We Want", aiming to "catalyze transformative ocean science solutions for sustainable development, connecting people and our ocean". It is an important resolution of the United Nations to promote sustainable marine development and the most important global marine science initiative in the next decade. It will have a far-reaching impact on the development of marine science and global ocean governance.

The Decade issued a "Call to Action" to all partners and received a wide response. The first batch of actions has been announced now, including more than 60 programs, activities and donations.
