Estimates show that 50% of the world’s corals have already been lost with as much as 90% loss projected by 2050. Consensus is building that even the strongest corals will struggle to withstand more frequent and more severe stressors in the future. But there is hope! Several recent research advances have demonstrated the potential for new tools in the study and engineering of corals. We created the Advanced Coral Toolkit program to promote the development and fielding of new biotechnologies that have the potential to greatly benefit coral resilience and restoration efforts. Below are the current and completed projects and their principal investigators.
