Eco Diving Courses

Fancy learning about the underwater world? An eco diving course is a great introduction to what’s actually going on under the waves, and how divers can help conserve it:

Reef Check Eco Diver: Reef Check is both a worldwide coral reef surveying methodology (coral reef monitoring, data recording and submission). Once certified, divers can join coral reef survey teams all over the world and gather data on coral reefs. This data then goes into a worldwide database which gives a overall view of the health of the world’s coral reefs.

Marine Resource Management: The Marine Resource Management Program goes deeper into the ecology and biology of the coral reef ecosystem and uses a fantastic manual from the University of Queensland as its guide – Coral Reefs & Climate Change – which divers get as part of the program. Gain an introduction to the coral nurseries, Biorock technology and other reef restoration projects that need constant attention.

Note: To join this course, divers must already be Reef Check certified (or equivalent).
