Solar radiation coral bleaching and climate change. (2004-2006)

Corals reefs like the Great Barrier Reef (GBR) underpin approximately $2 billion annually in sustainable tourism and fisheries. Warming of Australia s tropical seas however has increased mass coral bleaching/mortality and is placing reefs like the GBR at increasing risk. Solar radiation (PAR UVR) plays an important influence on the biological outcome of thermal stress. Understanding the role of solar radiation is critical if we are to understand the changes that will occur on coral reefs as temperatures increase. This multidisciplinary international team will define and model the role of solar radiation on thermal stress at local regional and global scales.
