Coral Reef Monitoring
We conduct ongoing coral reef monitoring in Trou aux Biches (Mauritius) to assess, track, and understand the health of local reef ecosystems. Using systematic surveys and scientific monitoring methods, we document coral condition, biodiversity, and environmental stressors over time. Our work supports conservation efforts, early detection of reef degradation, and informed decision-making to help protect and restore Mauritius’ valuable coral reefs.
Coral Observation
I
As we continue to expand our conservation and research initiatives, we are proud to be actively involved in coral observation through the CoralWatch citizen science programme. Our team regularly monitors the health of coral reefs, records observations, and submits our findings to the CoralWatch platform, contributing valuable data to a global network of reef conservation efforts.Healthy coral reefs are essential for marine biodiversity, coastal protection, and the livelihoods of many communities. By participating in CoralWatch, we are helping scientists better understand changes in reef health and the challenges our oceans face.We invite our local community, visitors, divers, and snorkellers to become part of this important journey. You don't have to be a scientist to make a difference—every observation contributes to protecting our reefs for future generations.Together, we can inspire ocean stewardship, support marine conservation, and ensure that our beautiful coral reefs continue to thrive. Join us and become a citizen scientist as we work to protect Mauritius' incredible underwater world.
When we conduct CoralWatch coral monitoring, we follow a simple scientific method that allows anyone to contribute valuable data on coral health.
What We Do During a CoralWatch Survey
-
Select healthy coral colonies to monitor.
-
Identify the type or growth form of the coral where possible.
-
Compare the coral's colour with the official CoralWatch Coral Health Chart.
-
Record the lightest and darkest colours observed on the coral colony.
-
Note any signs of stress, including:
-
Coral bleaching
-
Disease
-
Algae overgrowth
-
Sedimentation
-
Physical damage
-
Predation (such as Crown-of-Thorns starfish)
-
-
Record environmental information, including:
-
Dive site
-
Date and time
-
Depth
-
Water temperature (if available)
-
Visibility
-
-
Photograph the coral colony for future comparison and verification.
-
Upload the observations to the CoralWatch database, where the information becomes part of a global reef health monitoring programme.
Why It Matters
The colour of coral is an excellent indicator of its health. Changes in colour can reveal stress caused by rising sea temperatures, pollution, poor water quality, or other environmental pressures before a coral dies. By collecting this information regularly, we help scientists detect changes over time and better understand how reefs are responding to environmental change.
At Angie Sea, our coral monitoring trips give divers and snorkellers the opportunity to become citizen scientists. Every survey contributes valuable information that supports reef conservation in Mauritius and around the world. Together, we are helping to protect our oceans, one coral observation at a time.
