EddyCarbon is a commercial Localized Ocean Fertilization company. We deliver trace iron into the cores of marine eddies, mesoscale ocean vortices that already concentrate nutrients, life, and downward carbon flux. Then measure the response from the air above.
Satellite altimetry locates cold-core rotating features tens to hundreds of kilometres across with upwelled water at their centre. These are the ocean’s natural concentrators of nutrients and biology.
A precisely metered dose of bioavailable iron is released along the eddy’s core. The bloom that follows is the bloom the eddy was already trying to grow, finally unconstrained.
State-of-the-art autonomous buoys sit inside and outside the treated water, continuously sampling surface-ocean and atmospheric CO₂. The drawdown signal appears where the bloom did — and the buoys never blink.
Open-ocean fertilization is a fair criticism of an unfair design. Eddies fix that.
A marine eddy is a self-isolating parcel of seawater. Its rotation keeps the interior coherent for weeks to months, with sharp boundaries you can see from space. Iron added inside stays inside. The bloom that grows is measurable, contained, and finite.
That containment is what makes the work commercial. It is the difference between a science experiment and a verifiable ton of carbon.
Every ton we report is grounded in air-sea CO₂ data from instruments in the water. We do not model what we cannot measure.
Treatment is constrained to the rotating core of a single eddy. The ocean tells us where the perimeter is; we honor it.
The right dose is the smallest dose that triggers the bloom the eddy was already have had.
Buoy data is timestamped, signed, and made available to the people buying the removal. No black boxes between the sensor and the ledger.
We are building toward a pilot in the Subtropical Pacific. If you work in carbon procurement, ocean science, marine operations, instrumentation, or capital — we want to hear from you.
