In 2002, CoralWatch developed and validated the Coral Health Chart (Siebeck et al. (2006) Monitoring coral bleaching using a colour reference card. Coral Reefs 25:453-460). The chart standardises changes in coral colour, providing a simple way to quantify bleaching and monitor coral health. The Coral Health Chart is used by e.g. dive centres, scientists, governments, school groups, and tourists. Anyone can contribute to our global database! You don’t need extensive training – just download a Do-It-Yourself Kit, request a Coral Health Chart, and you are ready to go!
