One of the world’s leading coral reef scientists has called on the agency responsible for managing the Great Barrier Reef to release maps showing the extent of coral bleaching, after a key report was delayed with no reason given.

Aerial surveys of the sixth mass bleaching on the Great Barrier Reef were completed in March and are yet to be released. Previous events have been published within two weeks of completion.
