This app makes entering, uploading, viewing, editing and comparing your Coral Health Chart data on the CoralWatch global database easy and convenient.

CoralWatch is a citizen science project based at the University of Queensland, Australia. CoralWatch integrates global monitoring of coral bleaching with education about marine science and coral reef conservation.

In 2002, CoralWatch developed and validated the Coral Health Chart. This chart standardizes changes in coral color and provides a simple way that volunteers can quantify bleaching and monitor coral health without formal training. The Coral Health Chart is used by dive centers, scientists, school groups, and tourists and empowers people to monitor their own local reefs.

Anyone can contribute to our global database! You don’t need training – just download the CoralWatch Info App or Do it Yourself Kit from our website, request a Coral Health Chart, and you are ready to go!

Use this app to:

Record the GPS co-ordinates of your survey
Instantly see your data represented graphically
Store your survey data and upload at a later time
Contribute to the CoralWatch global database and improve the future of our reefs!
