30 Years of Reef Check!⁠
⁠
By the early 1990s, scientists suspected coral ecosystems were in serious trouble, but data didn’t exist.⁠
⁠
Enter Reef Check. ⁠
⁠
The mission was to create a methodology rigorous enough to satisfy scientists, yet simple enough that a recreational diver with no research background could execute it reliably on reefs anywhere in the world.⁠
⁠
2026 marks the 30th year of data collection for Reef Check’s coral reef monitoring program, representing one of the longest-running community-based coral reef monitoring efforts in the world. ⁠
⁠
We don’t plan on stopping anytime soon!⁠
⁠

Let’s jump in the water!⁠

When you’re in the water as much as we are, you get to see a little bit of everything, which means we often get to witness magic.⁠
⁠
But even the poor-visibility days are a blast because we know we’re doing our part to help the ocean and coastal communities.⁠
⁠
You too can support this mission by donating or volunteering!⁠
