Ocean carbon storage boosted by alkalinity enhancement, finds open-water trial Pilot project in Gulf of Maine assessing ocean geoengineering approach, finds it boosts carbon dioxide uptake

"The ocean is the largest carbon sink on Earth, holding about 38,000GT of carbon."

Obviously a little gutted that #OceanAlkalinityEnhancement got missed (😉). Bar the (frankly outrageous) scale it needs doing at, it has the advantages of being relatively benign (except maybe the end of the pipe), and one can arguably be lazier about #MRV (added TA *eventually* stores DIC).

Copepods are a key species in the marine food web. If their populations change, the whole food web changes. For this reason, our experts are intensively studying the possible consequences of #OceanAlkalinityEnhancement on copepods and the algae they feed on. Here are some results lnkd.in/efPmnKWd

Un peu plus de bicarbonate dans l’océan, et le réchauffement climatique fera pschitt? - Le Temps Une entreprise canadienne a entrepris de déverser une poudre de roche dans l’océan Atlantique pour accélérer l’absorption du carbone atmosphérique et le stocker durablement sous forme de bicarbonate. ...

L'océan ce "malade" : le "mettre sous perfusion" de substances alcalines est-il un bon remède au réchauffement climatique ?

We may have staged this photo a bit, but it was such a great day with colleagues from Hamburg University, discussing Carl’s PhD thesis on #oceanalkalinityenhancement @geomarkiel.bsky.social

It’s always better to do science with people you love working with

...and something from the other #OAE I am in love with.

Various ways to proceed with ocean alkalinity enhancement

‼️ Check out the  « Guide to Best Practices on Ocean Alkalinity Enhancement Research » that we release today.

A monumental undertaking: 53 authors teamed up to write 13 papers/chapters in less than 6 months.

Very interesting developments on the regulations of 'marine geoengineering' in Australia. I read this as an opening up to those activities, including #OceanAlkalinityEnhancement.

What do experts think?
