Playing OkCoral will teach you the basics you need to become a Citizen Scientist for the Coral Restoration Foundation! What is a Citizen Scientist? Citizen Scientists can be snorkelers or divers. As a Citizen Scientist, you can help us answer important questions about how well our corals are surviving and thriving on the reefs. We need this data so that we can keep adapting our methods. How much do I need to know? Not that much! By playing this app you will learn: 1) How to tell the difference between the two main species we work with 2) How to identify living and dead coral 3) What “fused” and “not fused” corals look like. Fused corals are clearly thriving! Let’s get started!
