Seagrass meadows are among the most efficient blue‑carbon ecosystems on the planet. Their dense root‑and‑rhizome networks trap organic material in the sediment, creating long‑term carbon stores that can persist for centuries.
To estimate how much carbon a meadow can sequester, scientists combine three key pieces of information: the spatial extent of the meadow (area), the rate at which carbon is buried each year (annual sequestration rate), and the time period over which the process is considered.
By multiplying these variables, we obtain the total amount of carbon removed from the atmosphere and locked into the seabed. This simple calculation helps managers compare the climate‑mitigation potential of different coastal habitats.
