Integrated Ocean Carbon Research: A Vision Primed for Implementation

 

The Intergovernmental Oceanographic Commission (IOC) of the United Nations Educational, Scientific and Cultural Organization (UNESCO) has released the Integrated Ocean Carbon Research (IOC-R) Report at the Ocean Sciences Meeting 2026. The report was developed by 72 authors from 23 countries, including contributions from current and former SOLAS Scientific Steering Committee members Philip Boyd, Minhan Dai, Erik van Doorn, Lisa Miller, Daiki Nomura and Parvadha Suntharalingam; SOLAS projects and networks representatives Dorothee Baker, Leticia Cotrim da Cunha, Sam Dupond and Siv K. Lauvset; and SOLAS Executive Director Li Li.

This report provides the most comprehensive assessment to date of how the ocean absorbs and stores carbon and identifies critical knowledge gaps that could shape climate action for decades to come.

It also identifies five focus areas for ocean carbon research:

• Evolution of the ocean carbon sink under a changing climate
• The changing role of biology in the ocean carbon cycle
• Carbon exchanges across the land-ocean-ice continuum
• The impact of ocean industrial processes on the ocean biological carbon cycle
• Future changes in the carbon cycle from deliberate ocean-based climate interventions

The report highlights four essential steps to reduce uncertainties and better align global climate action with the ocean's evolving role:

• Integrate global observing efforts across satellites, autonomous platforms, and sustained in‑situ measurements
• Refine models to better capture physical, chemical, and biological processes
• Strengthen scientific capacity worldwide, particularly in data‑limited regions
• Foster cross‑disciplinary research to connect scientific insight with societal needs
