Reef Watch is a simple one-dive-one-survey method to record the health of a coral reef and is used in conjunction with the Green Fins Conservation organization. Enthusiastic volunteers can help by learning the method and taking part in the program. Sadly, coral reefs are in trouble, with over 15% of reefs lost in the last decade and a further 30% in danger due to poorly planned human activities such as overfishing, global warming, pollution, and unsustainable tourism. The non-profit Reef Check Foundation offer the Reef Check EcoDiver program to provide education to divers to help monitor and protect these valuable ecosystems. The world's most biologically diverse marine system, coral reefs, are home to a quarter of all ocean dwelling fish. Coral reefs also feed, protect and inspire hundreds of millions of people around the world. On your dive or snorkel trip, you will be able to collect valuable information to help us care for the reefs you visit. The data you collect using the Reef Watch underwater slate will help us to see any trends developing on the reef. Your participation will provide us with valuable information to monitor the reef’s health.
