Durability is measured in years; permanence is forever. Why the distinction matters for ocean carbon credits, and how to compare tonnes honestly.

Ocean alkalinity enhancement removes CO2 by shifting seawater chemistry. Here is the drawdown chain, dose-by-dose: how much carbon, how fast, and where.
Dr. Lena Fischer ·
Ocean alkalinity enhancement removes carbon without planting anything. How is that measured? The chemistry, models and sensors behind OAE's proof problem.

No single body governs ocean carbon removal. From the London Protocol to national permits, here is the patchwork of rules taking shape — and the gaps.

Ocean biomass sinking proposes growing seaweed at the surface and sending it to the deep sea. An honest explainer of the physics, methods and the questions still open.

Seaweed sinking is the most contested idea in ocean carbon removal. Where the science has settled, where it hasn't, and five tests before crediting a tonne.
Dr. Lena Fischer ·
Beyond mangroves and kelp there is a fast-growing field of ocean carbon dioxide removal. Here is a clear map of the methods, their evidence, and their risks.

Ocean CDR credits span sinking biomass to alkalinity enhancement. A due-diligence framework on durability, MRV maturity, delivery risk and how to structure a purchase.

Sinking farmed kelp into the deep ocean could lock away carbon for centuries — or create new problems. A clear-eyed look at both sides of the seaweed debate.
Priya Raman ·
How ocean CDR field trials actually get permitted: research exemptions, environmental review, discharge rules, marine consent and community engagement.
Dr. Lena Fischer ·
Ocean alkalinity enhancement is a leading candidate for durable ocean carbon removal. How it works, what it might store, and the questions still open.
Dr. Lena Fischer ·
Adding alkalinity near kelp forests could store carbon and buffer acidification locally. What the chemistry promises, what ecology warns, and the safeguards that count.
