Advancing knowledge and cooperation for a healthy ocean and prosperous society
“From Knowledge to Action: Connecting Science, Policy, and Society for a Resilient Western Pacific”
Manila, the Philippines, 20–23 April 2027
First Announcement
The proposal submission periods indicated in this First Announcement have now closed.
The Government of the Philippines and the UNESCO/IOC[1] Sub-Commission for the Western Pacific (WESTPAC), together with a wide range of international and national partners, are pleased to announce that the 12th WESTPAC International Marine Science Conference & the 3rd UN Ocean Decade Regional Conference will be held in Manila, the Philippines, on 20–23 April 2027.
We cordially invite interested Member States, government agencies, institutions, and stakeholders to develop and submit proposals for Scientific Sessions, Decade Action Incubators, and Decade Action Workshops. Please refer to the detailed guidelines below.
Background
Covering 70% of our planet, the ocean is central to human well-being, as it sustains life, connects communities, and supports global development.
The ocean, seas, and coasts of the Western Pacific hold exceptional ecological, social, and economic value. As one of the Earth’s major heat engines, the region influences global climate and ocean circulation. It also harbors the world’s highest abundance and diversity of marine life, sustaining livelihoods, food security, and economic growth across the region and far beyond.
For the hundreds of millions who rely on the ocean for food, jobs, safety, and prosperity, a healthy and resilient Western Pacific is not optional – it is essential. Safeguarding our ocean health and securing a sustainable future requires lasting, collaborative, science-based, and innovative actions.
Since its inception, the UNESCO/IOC Sub-Commission for the Western Pacific (WESTPAC) has convened a triennial International Scientific Symposium[2] to advance ocean science, foster multi- and cross-disciplinary collaboration, and generate ocean knowledge for informed policy and management. Since 1986, a total of eleven International Scientific Symposia (now known as the International Marine Science Conference) have been organized, hosted on a rotational basis by Member States in the region.
To support the UN Decade of Ocean Science for Sustainable Development (2021–2030), the Sub-Commission convened the UN Ocean Decade Regional Kick-off Conference for the Western Pacific and its adjacent areas (online, 25–26 November 2021) and the 2nd UN Ocean Decade Regional Conference, held in conjunction with the 11th WESTPAC International Marine Science Conference (22–25 April 2024, Bangkok, Thailand), generously hosted by the Government of Thailand through the Ministry of Natural Resources and Environment and its Department of Marine and Coastal Resources.
Conference Objectives
The Conference seeks to bring together a wide range of ocean stakeholders, including governments, research communities and academia, the private and business sector, philanthropic foundations, UN agencies, NGOs, and civil society to:
- Present the latest developments in ocean science, knowledge, and innovations;
- Showcase and track achievements of UN Ocean Decade Actions in the region;
- Catalyze partnerships and concrete actions for transformative science-based solutions to sustainability challenges in the Western Pacific.
Abstract submission is open.
Submit your abstract to one of the 34 accepted Scientific Sessions by 15 November 2026.

Call for Proposals: Scientific Sessions
Proposal deadline: 31 May 2026 (proposal call closed)
Abstract submission is open until 15 November 2026.
The call invited interested government agencies, institutions, and stakeholder groups to propose Scientific Sessions to be held during the Conference. Proposed Scientific Sessions should address the following priority issues of Member States in the region:
- Ocean processes and climate change;
- Marine biodiversity conservation, seafood security, and blue economy;
- Ocean and human health;
- Marine disaster risk reduction and mitigation;
- Knowledge for emerging ocean issues, and cross-cutting themes such as ocean literacy and capacity development.
Scientific Sessions provide a platform to present, share, and exchange the latest scientific knowledge, identify knowledge gaps, and, where feasible, explore transformative ocean science solutions for a sustainable ocean and sustainable livelihoods in the region. Normally, each session consists of oral and poster presentations.
Responsibilities of Scientific Session Conveners
Conveners of accepted Scientific Sessions are responsible for the following:
- Session organization and delivery: Plan, coordinate, and oversee the execution of the session in close consultation with the Conference Secretariat;
- Session promotion: Encourage broad participation and identify potential co-sponsors with similar interests to support the session;
- Abstract review: Review submitted abstracts for relevance and quality and edit accepted abstracts as needed;
- Selection of presentations: Assign oral and poster presentations, identify backup oral presentations from accepted posters, and develop the session programme;
- Communication: Liaise with authors for clarification or confirmation of participation;
- Session reporting: Prepare a brief report summarizing key outcomes and recommendations after the session.

Call for Proposals: Decade Action Incubators
Proposal deadline: 15 August 2026 (proposal call closed)
Details of Decade Action Incubators will be published on the official conference website.
The call invited interested government agencies, institutions, and stakeholder groups to submit proposals for Decade Action Incubators to be convened during the Conference.
The Decade Action Incubator serves as an interactive forum to catalyze partnerships, strengthen dialogue between ocean knowledge generators and knowledge users, initiate co-design processes and facilitate the development of potential Decade programmes[1] or Decade projects[2]. Proposals are encouraged to consider cross-cutting topics including capacity development and support for Early Career Ocean Professionals (ECOPs). Each Incubator will run for a maximum of three hours.
The proposed Decade Action Incubator shall address one or more of the ten UN Ocean Decade Challenges[3]:
- Understand and beat marine pollution;
- Protect and restore ecosystems and biodiversity;
- Sustainably nourish the global population;
- Develop a sustainable, resilient and equitable ocean economy;
- Unlock ocean-based solutions to climate change;
- Increase community resilience to ocean and coastal risks;
- Sustainably expand the Global Ocean Observing System;
- Create a digital representation of the ocean;
- Skills, knowledge, technology and participation for all;
- Restore society’s relationship with the ocean.
Selection Criteria for Decade Action Incubators
Each proposal will be evaluated on both the quality of the Incubator session and the potential of the proposed Decade Action.
The basic criteria for selection include the following:
- Alignment with the vision and mission of the UN Ocean Decade, and contribution to the identified outcomes and challenges of the UN Ocean Decade;
- Generation of transformative ocean science in comparison to what has been done before;
- Promotion of a multidisciplinary, solution-oriented approach;
- Engagement of a broad range of stakeholders, and promotion of their interactions and actions;
