CoralWatch is a global citizen science program that integrates global coral bleaching monitoring with education and outreach to create reef awareness. CoralWatch is well-established program founded in 2002 and based at The University of Queensland, Brisbane, Australia. In 2002, CoralWatch developed and validated the Coral Health Chart (Siebeck et al. Monitoring coral bleaching using a colour reference card. Coral Reefs 2006(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 dive centres, scientists, school/university groups, conservation groups and tourists. Anyone can contribute to our global database! Simply match the colour on the chart with the colour of the coral and identify it's shape. You don’t need extensive training – just download a Do-it-Yourself Kit, request a Coral Health Chart, and you are ready to go!
