The Coral Reef Health Index screensaver ranks the world's major reef systems by real published health assessment scores. It is free, runs in your browser, and ESC exits.
How the Coral Reef Health Index screensaver works
The saver displays a real, curated ranking of major world reef systems by their published health assessment score.
Each reef shows its real reported health score out of 100, based on live coral cover and reef condition studies.
The board refreshes periodically as new real research assessments are published.
No live feed is required — figures are a real, curated periodic snapshot.
A worked example
A well-protected real reef system scores notably higher than one under heavy real bleaching stress, exactly matching published assessments.
