Reefs

The eReefs program monitors the Great Barrier Reef using satellite sensors high above the planet’s surface and from a unique marine observatory far below located in coastal waters of the Great Barrier Reef World Heritage Area.

A huge amount of effort is going into protecting the Great Barrier Reef - often the kilometres away from where the coral is actually living. Researchers now have a better understanding of the system of erosion and sediment transport processes connecting agricultural land with water quality in the Reef. Critical to improving land management practices.

There is an imperative to take action to protect and restore the Great Barrier Reef, the question is how we go about it. A new initiative is engaging the community in those decisions.

They're elusive, whale sharks, so we're keeping an eye on them using satellite tracking to see how far they travel and, in a world first, taking DNA samples to see just how old they are. Here they are on Ningaloo reef.

Here's one aspect of rising sea levels to think about - the loss in light reflected through ocean waters. Marine ecologists are asking, what are the limits, and threats, to coral skyscrapers? Because coral reefs don't just spread out - they also spread up.

A paper published in Nature Climate Change has revealed the importance of regional differences in sea surface temperature variability in determining the global distribution of coral bleaching risk.

Ningaloo Reef was declared a UNESCO World Heritage Area in 2011. Scientists are using tracking technology to better understand the region's unique and charismatic species.

The only way to prevent further severe coral bleaching on the world’s tropical reefs is to urgently reduce global warming, a new study reveals.
