Bleached corals are still alive, but they are starving, and often die in the following weeks.
Months after record breaking coral bleaching, research teams are taking stock of the damage on the Great Barrier Reef.
Don’t write it off just yet.
Once upon a time dead coral was something to be celebrated on the Great Barrier Reef.

The marine reserves review has recommended major changes to the Coral Sea, but not for the better.
Months after the bleaching event on the Great Barrier Reef, signs of the hoped-for recovery are scant.

Member of the Climate Council this week returned to one of the areas of the Great Barrier Reef that was worst affected by this year's coral bleaching. What they found was far from encouraging.
We think of coral reefs as a diverse ecosystem, but each coral is an entire and complex microworld of organisms imperceptible to our eyes.
Just like humans, corals live with myriad microscopic organisms. We are just starting to understand this unseen world.
Microbes living on corals are instrumental in keeping coral reefs healthy.
A new study provides insight into coral-dwelling microbial communities and how they react to pollution, overfishing, and climate change. What does it mean for the Great Barrier Reef?
Malcolm Turnbull and his colleagues have pointed $1 billion of the government’s existing green energy funding towards the Great Barrier Reef.
The Coalition has ramped up the race to fund the Great Barrier Reef's protection. All three major parties have promised hundreds of millions of dollars, but where from, and what will they be spent on?
Recent aerial surveys found huge amounts of coral bleaching in the Great Barrier Reef.

Bleaching has hit a huge swathe of the Great Barrier Reef, with many corals in the reef's remote northern reaches now expected to die as a result of warm waters linked to this summer's El Niño.
Bleaching events can leave corals weaker in the face of pollution and other stresses.

Authorities have moved the Great Barrier Reef onto its highest alert level in response to widespread coral bleaching. Months of monitoring will now be needed to assess the ongoing damage.

Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
The mussel hustle.
Shellfish will have more brittle shells as oceans get more acidic – making them more vulnerable to predators. New research gives a fascinating glimpse into how they will adapt.
Scuba diving must be done in a sustainable manner to preserve the industry.
Africa has a number of excellent scuba diving sites, but these must be maintained sustainably to keep attracting different divers.
You know what, I think we looked better before.
There are solar-power sea slugs, so why haven't humans mastered the art of photosynthesis?

Many corals can't make it through the bleaching events caused by warming ocean waters. But some can – and scientists are trying to learn more about the sources of their resilience.
Soon the oceans will be too warm to support thriving coral reefs.

Corals are experiencing only the third global bleaching event in recorded history, caused by warming seas. But worse is yet to come.
Give up, brain coral, we have you surrounded.

With their natural predators removed, sponges are free to take over coral reefs.
Coral reefs, the rain forests of the sea.
A new ecology study doesn’t focus on how people degrade the environment. Instead, it untangles the way physical factors in a pristine ecosystem drive the biology of what lives there.
One species, two colours.
The stunning colours of coral attract many divers to the world’s reefs but, for us coral scientists, one mystery has always remained. Swimming over a reef, you can frequently spot brightly coloured coral…
After mass bleaching in 1998, more than half of coral reefs in the Seychelles have slowly recovered.
Coral reefs are the poster child for the damage people are doing to the world’s oceans. Overfishing, pollution and declining water quality have all taken their toll on reefs around the world. Perhaps the…
