Marine biomass sinking
Marine biomass sinking takes organic matter from the ocean surface (such as harvested seaweed, agricultural waste, or other carbon-rich materials) and transports it to deep ocean sites where it's weighted and deliberately sunk to depths below 1000 meters, far beyond the reach of surface currents and oxygen-rich waters.
At these deep ocean depths, the cold temperatures, high pressure, and low-oxygen environment prevent the organic matter from decomposing and releasing its stored carbon back to the atmosphere. Instead, the material settles on the seafloor where it acts like an underwater carbon vault, keeping the captured CO₂ locked away for centuries or millennia instead of allowing it to return to the surface and contribute to climate change.
Marine biomass sinking transforms the deep ocean into a massive carbon storage facility that can sequester organic waste materials while leveraging the ocean's natural preservation conditions, creating a scalable solution that uses the planet's largest ecosystem as a long-term carbon repository.
