Plastic pollution is one of the most urgent threats facing our oceans — and understanding how to monitor and mitigate it is the first step toward creating real change.
In this 1-day course, you’ll explore how plastics enter marine environments, learn how to identify and quantify microplastics, and take part in hands-on clean-up and assessment activities both on land and in the water.
Accessible to everyone — snorkelers, divers, or even non-divers — this course empowers you to contribute meaningful data to global marine pollution databases and help protect Koh Tao’s fragile reef ecosystems.
Every year, millions of tons of plastic enter the ocean — breaking down into microplastics and harming wildlife, corals, and entire ecosystems.
This course gives you the scientific tools to understand the problem and take meaningful action.
What you’ll learn:
- Identify different types of marine plastics and their sources
- Understand how plastic pollution affects coral reefs, marine species, and human health
- Conduct microplastic surveys using scientific sampling methods
- Collect, classify, and quantify plastics during snorkel or dive surveys
- Record data to contribute to long-term marine pollution monitoring projects
This course is ideal if you want to:
- Take part in hands-on environmental action
- Learn scientific methods for assessing microplastics and debris
- Contribute data to global marine pollution research
- Complement your conservation training with an impactful, accessible specialty
