WELCOME! The goal of the 100 Island Challenge is to gain a holistic understanding of the current state and future trajectory of the world’s coral reefs by conducting a global assessment of coral reefs and the factors promoting or inhibiting their growth. This project is designed to provide a regional scale perspective of coral reefs, investigating spatially explicit patterns in community organization through time.
