The Allen Coral Atlas is a game-changing coral conservation tool led by Arizona State University and developed in partnership with coral reef scientists, universities, NGOs and private entities.

This online tool gives unprecedented access to data about the health of coral reefs around the world. It provides an up to date status of coral bleaching events and threat levels and gives detailed information on geomorphic zones, benthic classes and Marine Protected Areas. The interactive maps have multiple data layers that can be switched on and off.
