Learn to Monitor Health of Coral Reefs
You can become a marine protector and help to monitor the health of corals reefs using the Coral Health Chart and earn yourself a PADI Distinctive Specialty course certification.
This PADI Distinctive Specialty course is a collaboration between PADI AWARE and Coral Watch, both non-profit organisations, and the 1-day course helps students learn how to become citizen scientists by contributing data on reef health to a global database.

CoralWatch Specialty courses Open Water training dives
CoralWatch training dives are scientific dives, and dives can be longer than recreational dives, and students will be task-loaded with a coral health chart, a data slate, dive torch, and be expected to manage their buoyancy impeccably.
CoralWatch Survey Dive 1 in Open Water
On dive 1 your specialty diving instructor will assess your buoyancy to ensure your diver skills are good enough to be collecting data around coral reefs.
After evaluation of your buoyancy skills, and we are confident they are good enough, the first random survey can begin and using the coral health chart, you will be asked to identify suitable corals, their growth forms, and their color to help determine if any bleaching is evident.
We will ask you to conduct a random survey in a selected area and using the slate provided, to document the level of bleaching on corals that you find.
Throughout the training dives, you will be asked to remain a safe distance from the coral reefs to demonstrate proper buoyancy while conducting the survey and taking notes.
CoralWatch Survey Dive 2 in Open Water
On dive 2 you will conduct a second survey to collect data on coral growth forms, the level of coral bleaching seen, whilst demonstrating a high level of best practice diving skills.
Both dives include collecting data on healthy corals in addition to bleached corals, and your dive instructor will discuss the level of bleaching observed, reef health, and how to use the coral health chart to measure this.
After completing both dives, your instructor will also debrief on everything learned and discuss any problems encountered on the dives and how it can be improved next time.
Upon completion of two CoralWatch Open Water dives (or an extended snorkeling session) and submission of your data, you will be certified as a PADI AWARE CoralWatch specialty diver.

PADI AWARE CoralWatch – Learn about Coral Bleaching
CoralWatch work alongside volunteers worldwide and through education ensure that present and future generations understand the importance of coral reefs and how climate change is affecting this.
The Coral Health chart is an easy-to-use tool to help monitor the health of coral reefs by using color as a guide to determine the health of different coral species.
The chart uses different colors and numbers to represent the different stages of coral bleaching and coral reef recovery.
All certified divers should take their responsibility towards coral reefs one step further and become a certified PADI AWARE CoralWatch specialty diver.
