Seaweed on the ocean floor


This Portuguese based team are deploying and scaling an innovative solution to restoring seaweed in our oceans. Seaweed is a powerful tool for capturing carbon, absorbing more CO2 than trees. At the same time they create more fish in the sea, making our waters healthier. Rising sea temperatures, pollution, coastal developments and other factors are destroying these underwater carbon sinks. Luckily, this process is reversible and the team at SeaForester are utilising an innovative solution: “green gravel”. Unlike trees, seaweed needs no soil or fertiliser. Seaweed spores are seeded onto small stones, nurtured in nurseries before being scattered into the ocean. The stones latch on to the underlying reef, the seaweed grows and multiplies, spreading across the ocean floor and the seaweed forest returns.
