As the UN Decade of Ocean Science for Sustainable Development 2021-2030 (‘Ocean Decade’) enters its midpoint, a new batch of 39 Decade Actions is setting the stage for transformative ocean solutions. With momentum building toward the 2025 UN Ocean Conference in junho, these Actions exemplify the collaborative spirit driving ocean sustainability worldwide.
The newly recognized Decade Actions strengthen the existing portfolio of hundreds of initiatives endorsed by the Ocean Decade since 2021. With lead institutions spanning 21 countries – from Australia to Nicaragua, Nigeria, and Greece – the new initiatives address ocean pollution, coastal resilience, hands-on citizen science, and a sustainable ocean economy. They are primarily led by research institutions, non-governmental organizations, and the private sector.
“Decade Actions embrace a diverse range of profiles – some generate knowledge to fill critical gaps in our understanding of the ocean, while others build capacity and seek to influence decision-making,” said Vidar Helgesen, Executive Secretary of UNESCO’s Intergovernmental Oceanographic Commission (UNESCO-IOC). “With these initiatives targeting regional and thematic priorities for ocean action, including marine microbiome exploration, light pollution, marine energy, and coastal ecosystems, we continue to expand the role of the Ocean Decade as a global coordination and cooperation mechanism for ocean science across the globe.”

Tackling priority areas for ocean science
Three new Decade Programmes were officially acknowledged for their work towards the achievement of Challenge 1 – Understand and beat marine pollution, Challenge 4 – Develop a sustainable, resilient and equitable ocean economy, and Challenge 5 – Unlock ocean-based solutions to climate change.
Invisible yet vital to the Earth’s well-being, the ocean microbiome makes up over two-thirds of the ocean’s biomass. Led by Shanghai Ocean University, China, Deep Ocean Microbiomes and Ecosystems (DOME), which will focus on the polar regions and the little-known hadal trenches of the ocean, will work closely with other already endorsed Programmes working on similar issues such as the Ocean Biomolecular Observing Network (OBON), Challenger 150, Deep Ocean Observing Strategy (DOOS), and Marine Life 2030 to give a voice to this hidden majority of the ocean. By creating a global research network, DOME will explore deep ocean microbial diversity, ecosystem processes, and the ocean’s role in sustaining life amid climate change.
Closer to the surface, coastal cities, offshore oil rigs, and ships flood the ocean with artificial light, disrupting natural rhythms and threatening marine habitats. Headed by the University of Plymouth, UK, the Global Artificial Light at Night Network (GOALANN) provides insight into this often-overlooked form of pollution. The Programme convenes leading ocean experts to develop initiatives and tools, including open-access datasets, interactive maps, and policy briefings, to mitigate this growing issue.
Powering the Blue Economy – Global (PBE-Global) under the U.S. Department of Energy’s Water Power Technologies Office, is unlocking energy solutions for a sustainable ocean economy. Marine energy – harnessing power from waves, currents, tides, and temperature changes – is the world’s largest untapped renewable resource. PBE-Global shares knowledge, fosters collaboration, and builds capacity to advance marine energy technology for greater sustainability of industries and coastal communities.
Four Decade Projects implemented in and for Small Island Developing States (SIDS) and Africa focus on enhancing coastal resilience through video gaming, conserving kelp forests, engaging communities in wastewater management, and managing coastal pollution. Three additional Projects aim to address gender inequalities, inspire youth to become green ambassadors, and strengthen Indigenous leadership in decision-making.
A new and exciting area of deep ocean science under the newly endorsed ‘Dark oxygen production in the deep sea’ project will investigate how oxygen is produced on the abyssal ocean floor, along with its significance and broader implications. Led by the Scottish Association for Marine Science (SAMS) and supported by The Nippon Foundation, a long-standing partner of the IOC, this initiative seeks to deepen our understanding of deep-sea ecosystems and their essential role in sustaining life. For additional information on this groundbreaking discovery, see the recent coverage in Oceanographic Magazine here.
UNESCO-IOC, the only UN body dedicated solely to ocean science and the lead agency for the Ocean Decade, is adding two new Projects to its extensive list of Decade Actions – the largest of any UN organization. Implemented by its Regional Sub-Commission for the Western Pacific (WESTPAC) and Yunnan University, ‘Ocean Solutions in the East Asian Seas’ provides vital data on marine stressors to inform regional sustainable strategies and strengthen science-based conservation efforts. The Project ‘Enhance Coastal Resilience to Sea Level Hazards‘ will scale up UNESCO-IOC’s Tsunami Ready initiative in both existing and new countries, strengthening hazard preparedness in Small Island Developing States (SIDS) and Least Developed Countries (LDCs) through improved assessment, measurement, and forecasting.
Building knowledge and capacity for sustainable ocean management
Eleven new Decade Contributions have received official endorsement to support the implementation of the Ocean Decade. These initiatives will provide necessary funding or in-kind resources for global coastal resilience, marine sustainability, and ecosystem conservation with a focus on underrepresented groups and regions.
Among these, the OceanX and OceanQuest Around Africa Mission, led by OceanX, will support the Ocean Decade in tackling the pressing ocean challenges facing Africa. The exploratory mission will increase understanding of ocean circulation, ecosystem health, and marine biodiversity for sustainable resource management in this region.
Under its ‘Climate & Biodiversity Initiative,’ the C&BI – Ocean & Coastal Ecosystems co-branded call for projects by the BNP Paribas Foundation will fund initiatives exploring the climate-biodiversity nexus, science-driven solutions for ocean challenges, and adaptation strategies to scale up ecosystem-based management.
These new endorsements bring the total number of Ocean Decade Actions to 628, implemented on all continents and covering all ocean basins.
The current Call for Decade Actions No. 08/2024 is open until 31 janeiro 2025, aiming to bridge science and knowledge gaps in coastal resilience, society’s relationship with the ocean, and the ocean-human health nexus.

Sobre o Década do Oceano:
Proclamada em 2017 pela Assembleia Geral das Nações Unidas, a Década das Nações Unidas de Ciência Oceânica para o Desenvolvimento Sustentável (2021-2030) ("a Década do Oceano") procura estimular a ciência dos oceanos e a geração de conhecimentos para inverter o declínio do estado do sistema oceânico e catalisar novas oportunidades de desenvolvimento sustentável deste enorme ecossistema marinho. A visão do Década do Oceano é "a ciência de que precisamos para o oceano que queremos". O Década do Oceano fornece um quadro de convocação para cientistas e partes interessadas de diversos sectores para desenvolver o conhecimento científico e as parcerias necessárias para acelerar e aproveitar os avanços na ciência dos oceanos para alcançar uma melhor compreensão do sistema oceânico e fornecer soluções baseadas na ciência para alcançar a Agenda 2030. A Assembleia Geral da ONU mandatou a Comissão Oceanográfica Intergovernamental (COI) da UNESCO para coordenar os preparativos e a implementação da Década.
Sobre a UNESCO-IOC:
A Comissão Oceanográfica Intergovernamental da UNESCO (UNESCO-IOC) promove a cooperação internacional em ciências marinhas para melhorar a gestão dos oceanos, das costas e dos recursos marinhos. A COI permite que os seus 150 Estados-Membros trabalhem em conjunto através da coordenação de programas de desenvolvimento de capacidades, observações e serviços oceânicos, ciência oceânica e alerta de tsunami. O trabalho do COI contribui para a missão da UNESCO de promover o avanço da ciência e das suas aplicações para desenvolver o conhecimento e as capacidades, fundamentais para o progresso económico e social, base da paz e do desenvolvimento sustentável.
