Survey Methods

The Coral Health Chart can be used while diving, snorkeling or reefwalking. You can choose a monitoring method that suits your skills, experience and location. Most people use the random survey method.
There is no strict protocol that you must follow when using the Coral Health Chart. We encourage you to develop your own methodology and incorporate the Chart to suit your needs, be it research, education, or mere curiosity. Use the chart to measure coral bleaching while on a relaxing dive, to regularly monitor corals along permanent transects for a science project, or simply to assess the current status of your local reef. Please do remember to enter your data with our data entry app or directly on our website.
