Seagrass roots accumulate vertically beneath the seafloor, creating a vast repository of buried blue carbon.
Clustered along tropical and subtropical coastlines, mangroves are among the most efficient carbon capture and storage systems on the planet.
Salt marshes sequester carbon at a much higher rate than land ecosystems, but have lost more than 50% of their historical global coverage.
The ocean collects and stores vast amounts of carbon in seabed sediment, vegetation, marine animals and the seawater itself.
