No single experiment can answer all questions about ocean iron fertilization for mCDR. 🌊

We’re excited to announce the ExOIS Field Research Coalition, bringing together independent research programs to share knowledge & advance responsible OIF research.

New international coalition establishes shared principles for responsible research into ocean iron-based carbon removal
New York (Sept. 25, 2026) — As scientists and policymakers increasingly consider environmentally based approaches to climate mitigation, a new international coalition of research organizations is calling for rigorous, coordinated study of ocean iron fertilization (OIF) and its potential role in marine carbon dioxide removal (mCDR). The ExOIS Field Research Coalition, convened by Exploring Ocean Iron Solutions (ExOIS), brings together independent organizations developing OIF field programs in different regions of the global ocean. The coalition aims to advance scientific understanding through greater coordination, information sharing, transparency, and common standards for responsible research. Founding members have signed a voluntary charter committing to scientific excellence, environmental stewardship, transparency and scientific independence, collaborative learning, and research conducted in the public interest. In addition, members have committed not to seek direct financial gain from their research during the experimental phase, including through the sale of carbon credits and offsets, helping to ensure that research findings remain impartial and independent. The coalition also recognizes that OIF and other ocean-based climate-mitigation techniques remain areas of active scientific investigation. Their potential effectiveness, environmental impacts, risks, and broader implications require continued research and careful evaluation before conclusions can be drawn about their suitability or scalability as climate-mitigation strategies...

A great opportunity to come and work with the ExOIS program office and @whoi.edu
🌊The ExOIS program office has an opening for a short-term position to help with the writing of an application for a permit for ocean iron fertilization #OIF field research in the high seas

✅Nesta semana, uma equipe de 17 cientistas dos 🇺🇸, 🇨🇳, 🇯🇵, 🇨🇦 e 🇰🇷 apresentou uma proposta inusitada p enfrentar as mudanças climáticas: fertilizar os oceanos com ferro. A ideia foi divulgada pela organização sem fins lucrativos Exploring Ocean Iron Solutions (ExOIS)👇

Last week at the AGU25 Annual Meeting, my postdoctoral advisor, Ken Buesseler, received the AGU Ambassador Award. It was a pleasure to join him in celebrating this well‑deserved honor. @cafethorium.bsky.social @exois-oceaniron.bsky.social

Ocean iron fertilization is one of the trickiest mCDR pathways to verify. Export flux below the mixed layer, remineralization depth, and ecosystem effects all complicate durability claims. Glad to see ExOIS putting principles up front.

This is a nice piece covering how adding iron to the ocean can help stabilize the climate - the time for action is here #oceaniron @exois-oceaniron.bsky.social

Are you at #UNOC3? Come to an ExOIS-hosted off-site side event next Tues to discuss environmental and ecological #MRV #eMRV to build trust and confidence in #mCDR research. We’ll have pizza and a tasty bev, so don’t be late!

On to the poster session #1 at #LiegeOcean25! Come by and say hi - I’ll be at the @exois-oceaniron.bsky.social poster in the back corner, come chat with me to learn more about what we think still needs to be done to evaluate OIF for mCDR

Excited to be here in Liège representing @exois-oceaniron.bsky.social with Mark Wells at #LiegeOcean25 on marine carbon dioxide removal, and our work developing the next generation of #oceanironfertilization field studies
And we're ready for a new edition of the #LiegeOcean25 Liège Colloquium! Looking forward to meeting everyone on Monday!

I know why it’s easy to want to reject this idea full stop, but I suggest reading the latest Paths Forward report from ExOIS. oceaniron.org/our-plan/
