Theory component

There are five e-learning sessions where you learn about the fundamentals of coral reefs and coral reef monitoring. This includes their function and importance. You’ll then go on to learn about the driving forces behind the decline of coral reefs and what measures we take to halt this decline. Then, the course continues with an introduction to Reef Check and the Reef Check protocol for coral reef monitoring. This includes the tools, terminology, key concepts, and methods used in the field for monitoring the health of coral reefs with Reef Check. Next, you will learn to identify the indicator species used in your region to estimate coral reef health and the methods to survey them. This will allow you to get an in-depth view of fish, substrate, invertebrate, coral disease, and impact identification for monitoring.

Next, your knowledge to identify and survey fishes, substrate categories (corals, sponges, algae, etc.), invertebrates, and coral diseases will be applied and tested in three separate open water sessions. Then, all knowledge and skills learned will be put into practice in your last dive where you will conduct a full Reef Check survey. Finally, you will experience capturing and interpreting the data on coral reef health collected by you and your team.

Responsible Diving System for responible reef useAs part of our mission, Corales de Paz believes that there are three distinct components for creating a snorkeling and diving industry that has a net positive environmental impact. The three components are knowledge, skills, and behavior, and together form the Corales de Paz Sistema de Buceo Responsable de Corales de Paz que te ayuda a asegurarte de que siempre pones más de lo que tomas de los arrecifes de coral.

A reef user like you, (e.g. beachgoer, snorkeler or diver) must have a proper foundation of knowledge to understand how coral reefs function, and their strong connection with humans, to be aware of the impact you are causing to coral reefs. Practical training offers you the opportunity to develop the skills necessary to measure and reduce the impact caused on coral reefs.

Your introduction to Meaningful Diving!

The Reef Check EcoDiver course is the second level of the Reef Check EcoDiver program and an entry-level in our Universo de Buceo con Propósito, a group of courses and training we believe provides important knowledge and skills for the ocean lovers and reef users like you to actively engage in building coral reef resilience.
