Kia Ora Welcome!

The local organising committee warmly invites you to join us for...

Mā te kōrero, kia mārama. Mā te mārama, kia mahi tahi. Mā te mahi tahi, kia mōhio.
The 6th International Symposium on the Ocean in a High-CO₂ World

Moving from Understanding to Action using Multiple Knowledge Systems

Held in Wellington, New Zealand, at Tākina Convention & Exhibition Centre. Join researchers and other thought leaders from across the globe to explore the impacts of rising CO₂ and help shape future ocean science solutions. Experience Wellington through ecosanctuary tours, SCUBA dives in Taputeranga Marine Reserve, and a wide range of technical workshops.

Ngā Uri o Taranaki Whānui have generously gifted the Symposium's name in recognition of the partnerships that have collectively developed this symposium.

Ocean Ecosystems

In conjunction with the BMC journal Ocean Ecosystems, there will be a Collection of articles that focus on the impacts of high CO₂ and climate change drivers on marine ecosystems and organisms that celebrates the research presented at the symposium and beyond.

Submission deadline: 15 March 2027

About the Symposium

Ocean acidification remains a central theme of the symposium series. This edition will also expand to consider other ocean climate impacts, such as ocean warming and deoxygenation, particularly in a multiple-driver context. Research on marine carbon dioxide removal interventions, which are suggested to mitigate climate change and ocean acidification, will also be a key part of the conference.

Themes

Beyond tipping points - translating science to action
Global-driven changes in biodiversity and ecosystem resilience
Multiple stressors' effects on marine organisms
Ocean-based solutions
Technological advances in marine climate change research
The modulating role of time - from short-term variability to evolution
Working across knowledge systems in a high-CO₂ world

Workshops, Meetings & Training

There are over 22 free workshops covering a wide range of topics, including marine carbon dioxide removal (mCDR), learning across knowledge systems, policy engagement, integrating ocean carbon observations and models, experimental design, and biodiversity in a changing ocean. Space in many workshops is limited, so make sure to sign up when you register.
