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…
Healthy coral on the Great Barrier Reef. New research shows that corals exposed to dredging have increased risk of disease.
Dredging has a direct impact on coral health, according to a study published today in PLoS ONE that shows for the first time…
Already operating as a coal port, the disposal of dredge material from expanding Abbot Point is now the subject of a legal challenge.
The Great Barrier Reef Marine Park Authority’s recent decision to allow 3 million cubic metres of dredge material to be disposed of 25 kilometres off Abbot Point in north Queensland has attracted passionate…
Long-lived deep-sea corals preserve evidence of a major shift in the Pacific Ocean ecosystem since 1850. The tree-like skeletons…
Coral reefs under the business-as-usual-emission scenario, will quickly decalcify and dissolve.
The world’s coral reefs will quickly dissolve if greenhouse gas emissions continue on current trends, a new simulation has…
Air pollution has been found to have affected coral growth in the Caribbean over many decades.

Tiny particles of air pollution can stunt the growth of coral reefs, according to a new study in Nature Geoscience. Using…
Traditional methods of determining past ocean temperatures through coral studies have had to be rethought. Research conducted…
Australian reefs are particularly susceptible to the effects of climate change, not only because of temperature, but also…
