The UN Decade of Ocean Science for Sustainable Development (2021-2030) was taken up through the Intergovernmental Oceanographic Commission (IOC) of UNESCO. This global program encompasses all ocean sustainability enthusiasts world-wide. The Institution of Electrical and Electronic Engineers (IEEE) being the largest professional body in the world, its chapter, Oceanic Engineering Society (OES) has taken up many activities connected with this through its Ocean Decade Initiative (ODI). The Ocean Decade Fact Check Panel convened on September 26, 2024, during the OCEANS Halifax conference organized by the IEEE OES ODI. The overarching topic was to assess the progress of the UN Decade of Ocean Science for Sustainable Development, identifying gaps, assessing the impact of societies like IEEE OES and outlining future steps. While this is too large a task to do justice to in a single panel, the idea was to look at it through a few different lenses relevant to the panel’s expertise – the lens of technology, ocean engineering, the role of ocean observation systems, and the role of professional societies and networking groups. Dr. Hari Vishnu, Senior Research Fellow at the National University of Singapore and member of the ODI, moderated the session and guided the six speakers through the event. The insights shared in the panel were expected to contribute valuable perspectives for the global ocean observing community and help shape future discussions and actions, including those of the professional societies gathered at the OCEANS Halifax conference.

The following speakers were on the panel:
- Anya Waite, CEO and Scientific Director, Ocean Frontier Institute; Global Ocean Observing System (GOOS) co-chair 2020-2024; co-lead of the GOOS Carbon Exemplar and Associate Vice-President Research of Dalhousie University. Anya previously served as Head of Polar Biological Oceanography at Alfred Wegener Institute and Professor in the University of Bremen.
- Rene Garéllo, Professor Emeritus, President of IEEE France, Life Fellow IEEE, Past President of IEEE OES
- Brian Sellar, Reader at the University of Edinburgh specializing in the interfacing of field measurements, tank-testing and numerical simulations. He has led advanced multi-year in-situ measurement and wave-current modeling campaigns in tidal channels in the UK and Europe and has over 10 years of experience in this area.
- Malcolm Heron, Adjunct Professor at James Cook University and CEO of Portmap Remote Ocean Sensing Ltd, and an expert in electromagnetic wave propagation applied to ocean science, Life Fellow, IEEE and Exec-VP of IEEE OES
- Venugopalan Pallayil, Vice President for OCEANS at IEEE OES, Principal Research Fellow & Deputy Head at Acoustic Research Laboratory, National University of Singapore with considerable research experience in underwater acoustics.
- Ronnie Noonan-Birch, a marine socio-ecologist at the Ocean Frontier Institute, who focuses on the nexus of human well-being and ocean health. Her thesis on Canada’s blue economy operationalized the sustainable development goals to create an assessment framework for social equity, environmental sustainability, and economic viability of the ocean industry
The discussion centered on key accomplishments, identified critical gaps, and explored opportunities for enhancing ocean sustainability, particularly in areas such as marine pollution, renewable energy, data management, and coastal ocean safety.
At the outset, Hari outlined what the Decade was about, its seven desired Decadal Outcomes and 10 Decadal challenges, and what has been reported on the progress of the Decade so far in terms of numbers, drawing from the Ocean Decade Progress Report 2022-2023. This set the context for the framework within which to understand the panelists’ takes, and to get a feel of the quantitative assessment before discussing it qualitatively. In summary, the report mentions that as of June 2023, the Decade has endorsed 47 Programmes, 277 Projects, and 85 Contributions across 58 countries. These Actions have created over 25,000 knowledge products, capacity development activities have supported more than 200,000 beneficiaries, and 39 National Decade Committee’s activities have impacted more than 1 million people. The decade is now the Largest global ocean science initiative ever undertaken, and will continue to engage philanthropic entities, Small Island Developing States (SIDS), Least Developed Countries (LDCs) and Early Career Ocean Professionals (ECOPs), including supporting regional task forces and coordination structures.

Achievements and Future Directions
Anya Waite started the discussion, focusing on the GOOS, which caters to Decadal challenges 7 and 8, and highlighting the gaps in current ocean observations. She noted that the Ocean Decade has successfully amplified communication around ocean science, sparking widespread conversations and projects. However, the initiative is now at a critical juncture where continued momentum depends on securing external resources. She compared the situation to a high-demand oxygen system—without sufficient input, such as funding from key contributors like the United States to IOC-UNESCO and the GOOS, the initiative risks stagnation. As the Decade progresses, the challenge is to not only maintain this momentum but also ensure efficient resource allocation and long-term sustainability. She invited a robust and diverse discussion on this topic from the panelists and audience.
Marine Pollution and Changing Ocean Relationships
Building on Anya’s insights, the discussion then moved the Decadal outcome #1: A Clean ocean, and the first decadal challenge of understanding and beating marine pollution. Rene emphasized the importance of reducing marine pollution and debris and highlighted that there are hardly any beaches to be found without plastic these days. Beyond pollution reduction, there is a broader need to change how societies interact with the ocean, ensuring its sustainable use. The diversity of expertise and solutions within the Ocean Decade—such as contributions from Ocean Environmental Solutions—is vital in achieving this transformation.

Offshore Renewable Energy and Data Management
One of the key contributors to ocean pollution is carbon dioxide from fossil fuel-based power plants. Dr. Brian Sellar then shifted the focus of the discussion towards engineering interventions such as ocean energy observation systems. Offshore renewable energy, particularly wave and tidal energy holds great potential for the sustainable energy transition. However, Brian highlighted the complexities of obtaining the right data—at the right place, at the right time, and at the right cost. Multidisciplinary collaboration and open data-sharing models are essential for overcoming these challenges. Furthermore, there is a pressing need for capacity building, ensuring that available resources are maximized while additional capabilities are developed. As an example, Brian pointed out the dire shortage of professionals and students in his research region in Scotland.
Sustainability and Safety in the Coastal Ocean
The panel then moved to the 7th and 8th Decadal challenges. Malcolm Heron discussed advancements in ocean observation sensors and platforms, and the gaps in best practices, standards, and access to reliable science. He pointed out that there is also a surge in unreliable literature being published based on beliefs rather than real science. For instance, despite common belief, tropical cyclones are decreasing in Australia, as the data shows. Thus, there is a need to improve the reliability of published scientific literature. He also noted that tsunami warning systems are underdeveloped, and valuable data is often underutilized. Moving forward, technologies such as artificial intelligence and distributed acoustic sensing could play a crucial role in addressing these gaps, and he outlined these two technologies as enablers in the coming years.
Role of Professional Societies
Transitioning from engineering interventions, the moderator pointed out that the Decade is not just about science and technology, but also about connecting or activating people and groups of people. With this in mind, the next panelist, Venugopalan Pallayil, was introduced to present the impact of professional societies such as IEEE-OES on the Decade. Venugopalan discussed how the OES has been able to play a central part in connecting networks of experts to present viewpoints to society and contributing to science communication, capacity building and information dissemination via several activities. These include, but are not limited to, activities at OCEANS conferences, community-level activities and Ocean educational content generation led by OES chapters across the world, and student ocean technology competitions, thus touching upon the 9th and 10th Decadal challenges – skills, knowledge and technology for all, and to change humanity’s relationship with the ocean.
Ocean Observing and the ECOP Blue Economy
Ronnie underscored the critical role of ocean observation in the success of the Ocean Decade. Proper ocean observing systems, co-designed with stakeholders, are necessary to meet societal needs. Ronnie specifically touched upon how the concept of co-design is crucial to the Decade. While enthusiasm for ocean science has generated excitement, the challenge now is to convert this into a sustainable investment. Ronnie also brought to the panel the voice from the ECOP community, which although has been highly activated, connected and collaborative during the Decade, is stretched thin with too many voluntary commitments during this time. Transitioning from volunteer efforts to funded initiatives is essential for continued progress.
The ensuing questions and discussions highlighted the following additional challenges, gaps and potential solutions/enablers for the Decade:
Challenges, Gaps and Solutions
Innovation and Co-Design: One key challenge is the need for interoperable systems that enable effective data exchange across regions and sectors. There is also a strong need for improved communication of regional expertise and differences, ensuring that co-designed solutions are tailored to local needs.
Funding and Sustainability: Funding continues to be a major obstacle. Engaging the industry, particularly in ocean tech, banking, and insurance sectors, is vital. There is also potential for philanthropic funding and stronger industry-academic collaborations. The GOOS, which holds one of the most comprehensive ocean data sets, is critically underfunded. A proposed solution is a “GOOS tax” to ensure continuous funding and operations.
Collaboration and Stakeholder Engagement: Collaboration is key to the Ocean Decade’s success. Identifying and engaging the right stakeholders, such as Autonomous Underwater Vehicle (AUV) operators, can help optimize resource sharing. Building sustainable partnerships across sectors—academic, governmental, and industrial—will be crucial to address resource shortages and ensure the continuity of long-term projects.
Translating Data for Decision-Makers: A critical gap exists in translating scientific knowledge into actionable insights for decision-makers. Many legal frameworks governing ocean and climate policies are outdated. Updated scientific findings must be communicated to legal and policy experts to prompt necessary regulatory changes.
At the end of the panel, the moderator pointed out that this discussion and stock-taking exercise should continue robustly throughout the Decade to guide action and change, and mentioned that this exercise would be undertaken over the next few OCEANS conferences too. He invited the audience to provide their input on what they thought were the scientific/technological/operational gaps that needed to be tackled in the Ocean Decade, via an online poll. The responses from the audience were instructive and included broad themes such as indigenous engagement, building communities of practice, gathering consent for renewables, engagement with the law, successful collaboration, interested tool sharing, ocean literacy, effective science communication, increased tool sharing, interoperability, shared purpose and bridging the skills gap. These were reflective of the themes identified for the Decade itself under its Outcomes and Challenges.
Conclusion
The Ocean Decade Fact Check Panel highlighted significant progress in ocean science and sustainability but also identified pressing challenges—particularly in securing funding, utilizing data effectively, tackling biased science and influencing policy. Multidisciplinary collaboration, industry engagement, and innovation in data management and renewable energy are key to sustaining the momentum of the Ocean Decade. Technology enablers, such as distributed acoustic sensing and artificial intelligence, have been taking centre-stage in managing the technological needs of the Decade, but face challenges in terms of adoption and operationalization. As it moves into its second half, the initiative must focus on turning excitement and voluntary efforts into funded, actionable programs that will drive long-term positive outcomes for ocean health and resilience.
