Global map of average annual carbon storage potential by coastal ecosystems world wide in millions of tonnes of carbon per year. Estimates range from up to 0.15 million tonnes per year (lightest green) around Greenland, the west coast of South America, and around Antarctica, to up to 11 million tonnes per year (dark blue) around Australia, Indonesia, and the United States. These data are part of an analysis of which countries are donating natural carbon-storage services to the planet and which countries are recipients of other countries' natural services.
