This program will make open your eyes to a whole new underwater world
Most complete coverage of the marine ecosystem available in a short course today
Making your dives count, not just counting your dives
Join Reef Check surveys around the globe
Become a buoyancy expert
Reef Check Diver Course enables you to participate in Reef Check Surveys around the world. (Must be PADI Advanced or equivalent to apply). This volunteer program is especially suitable for:
Age 18+
Become certified to conduct your own Reef Check surveys and take an active role in conserving your favorite coral reefs. 

This course is designed to teach you everything you need to know to conduct full scale Reef Check surveys. 

In this program you will learn all about the globally standardized Reef Check methodology as well as how to identify key indicator fish, invertebrates and substrates selected by Reef Check for global monitoring and conservation of coral reefs! 

This course will allow you to join the Reef Check monitoring team and assist in underwater surveys around the world.  We are fortunate here on Koh Tao that we have several permanent transects that we regularly survey.

Reef Check is the most complete coverage of the marine ecosystem available in a short course today. You will discover a whole new world you had previously overlooked simply because no one has made you aware of it.

Reef Check partners with companies like OceanWatch, which sails the South Pacific assisting indigenous cultures to develop better ways to fish and ,manage their local environments.

The oceans are in danger, especially coral reefs ans survey teams like Reef Check provide invaluable data to help manage and monitor resources. Without this information, how do we know they are changing?  Scientists and politicians want hard data to make informed decisions.

Prerequisite:   Advanced Certified Scuba Diver (PADI or equivalent) If you are not yet a scuba diver, we can conduct this training before starting this course.   Strongly recommend:  Peak Performance Buoyancy Specialty 

Requirements: Participant is comfortable using mask, fins and snorkel or is a certified advanced scuba diver. Age of 12 or above.

After completion of the course students can participate in some of our other conservation dives with our ECO team conducting coral research / monitoring corals.  Trainers will be testing and building on students knowledge about the aquatic realm on every dives. 
We regularly conduct CoralWatch dives which is a non-invasive tool to quantify coral bleaching and monitor coral health.  Data is collected, transferred into a global database by using a simple App.  All data is publically available to enable you to compare the condition of different reefs at any one point in time.  A great monitoring and education tool to increase awareness of reef health and encourage behavior change towards a sustainable , low carbon future. Other conservation dives include predation removal, coral nursery maintenance, fish / invertebrate surveys and water testing. 

Typical day

The course will begin with coral ecology, background in Reef Check, it's methodology as well as identification training for fish, invertebrates and substrates for generalized geographic locations.

Mornings presentations - Fish, Invertebrates and Substrate identification taught by our Reef Check Trainer

Afternoons you'll be diving putting the theory into practice alongside our Reef Check Trainer and on our final dives we'll be conducting a real Reef Check Survey  and submitting the data online to our Reef Check Scientist / Reef Check HQ
