Project Introduction


ReefTemp is a mapping product that provides information on coral bleaching risk for the Great Barrier Reef region. It is a collaborative project between CSIRO Marine and Atmospheric Research, the Great Barrier Reef Marine Park Authority and the Bureau of Meteorology.

Climate change projections for the Great Barrier Reef include increased frequency and severity of mass coral bleaching events. ReefTemp produces high-resolution now-casts of bleaching risk and provides an improved ability to monitor heat stress in the Great Barrier Reef. To view the most current ReefTemp images click here.
