Africa: The World’s Coral Reefs Are Bigger Than We Thought – but It Took Satellites, Snorkels and Machine Learning to See Them
[ad_1] The world's coral reefs are close to 25% larger than we thought. By using satellite images, machine learning and on-ground knowledge from a global network of people living and working on coral reefs, we found an extra 64,000 square kilometres of coral reefs - an area the size of Ireland.
