1 Day
Theory + Fieldwork

Experience the life of a marine biologist for a day! Show you care about coral reef conservation, commit to take actions to reduce your impact, and experience how the world does coral reef monitoring.

You will experience how you can protect coral reefs while diving with Reef Check. You will become a marine scientist for a day and help coral reef monitoring. In the end, you will leave with most of your questions answered on the work marine biologists do. The best is that everyone can join, whether a snorkeler or a diver.


The Discover Reef Check half-day course allows you to see firsthand how marine biologists conduct coral reef research.  It is an introductory course for individuals to learn the basic principles of coral reef monitoring using the globally standardized Reef Check monitoring methods. The main focus is to provide insight into how these scientific techniques and equipment are applied in the field. Following an introduction, you will try your hand at some of the sampling techniques used in coral reef monitoring.

Theory component

There is a two-hours in-person or e-learning session where you learn about the fundamentals of coral reefs. This includes their function and importance. You’ll then go on to learn about the driving forces behind the decline of coral reefs and how are scientists evaluating the condition and health of coral reefs. Finally, you’ll have time to reflect on what can be done to aid in the future of coral reef conservation. This will touch on how coral reef monitoring can assist in coral reef conservation.

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 Responsible Diving System which helps you ensure that you always put more than what you take from coral reefs.

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 to coral reefs.

Your introduction to Meaningful Diving!

The Discover Reef Check EcoDiver course is the entry level of the Reef Check EcoDiver program and an entry-level in our Meaningful Diving Universe, a group of courses and training we believe provide important knowledge and skills for ocean lovers and reef users like you to actively engage in building coral reef resilience.
