Science + Innovation to Save Coral Reefs
Our team is tackling the coral reef crisis with every tool in its Toolkit.
Taking Action
Half the world’s coral reefs have disappeared in the last 70 years—and the rest could be gone by 2100 if we don’t take action
Developing Solutions
We're working to rebuild reefs and improve coral resilience—before it’s too late.
Diagnostics & Intervention
Since 2021, we’ve applied our Toolkit to reefs in the US Virgin Islands—and now we're taking it around the world!
Robotics
- Map coral cover + condition
- Collect biodiversity + invasive species data
- Early warning system for bleaching
Bioacoustics
- Attract coral larvae
- Sound-based health diagnostics
- Understand fisheries+ ecosystem health
Advanced Diagnostics
- Monitor coral health
- Determine water quality
- Examine chemical + microbial signs of stress
Hydrodynamics
- Map currents + temperature
- Predict coral larval transport + settlement
- Model + forecast environmental changes
- Identify + prioritize restoration sites
Health Interventions
- Coral probiotics
- Vitamin supplements
- Metabolomics to diagnose+ treat disease
Reef Solutions Around the World
We’re bringing our research from the US Virgin Islands to vulnerable reefs around the world.

“If coral reefs are going to survive, they need people to understand the problems, science to develop solutions, and technology to scale up the solutions to reach all reefs. We’re implementing a plan to help corals in crisis– and with your support, give reefs a chance.”
