Marine sponges are ancient organisms that have survived mass extinctions. Many are more tolerant of climate change and may dominate over corals in future reef systems.
Ocean acidification poses an increasing threat to the sediments that form the framework of coral reefs - within around 30 years, these carbonate sands may no longer be able to form.
The federal government's new funding aims to spread the net wide in investigating possible ways to protect the Great Barrier Reef's corals. Winning this battle will require a wide range of weapons.
A new study suggests the benefits of a boost to marine plant growth from increased carbon dioxide will be cancelled out by the increased stress to fish species.
IPSO's latest ruling makes a mockery of journalism's commitment to seeking the truth.
Warming waters due to climate change are losing oxygen, threatening the health of fish and ecosystems.
The oceans are filled with sounds produced by animals. However, a recent study shows that ocean sounds are diminishing due to nutrient pollution and ocean acidification.
Global climate change is altering the chemistry of the oceans. A recent study suggests that the Pacific coast's lucrative Dungeness crab fishery could suffer as ocean water becomes more acidic.
Atmospheric, marine, environmental, biological and medical scientists join in calling for more focus on the damage being wrought by climate change.
Tiny organisms change ocean acidity to benefit themselves.
'Smell-free seas' would be a disaster for marine life.
A combination of factors – pollution, disease and overfishing – is harming corals but scientists have found clues to effective treatment by studying corals' microbiome.
South Africa has the opportunity to benefit from its ocean economy. But to do that, the country needs to put better policies in place to counter ocean acidification.
Marine scientists have been accused of being biased towards 'doom and gloom'. But it's not bias if the outlook for coral reefs really is gloomy.
By artificially going 'back in time' to more alkaline ocean conditions, researchers have shown the damage that ocean acidification is already doing to the Great Barrier Reef.
Ocean acidification will hurt some parts of the Great Barrier Reef more than others.
Without action to curb the rising acidity of our seas, corals will start to develop deformed skeletons at a crucial young stage of their lives.
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.
We know a lot about the potential negative effects of ocean acidification on marine creatures. But might some species actually benefit? The answer is yes, but this isn't necessarily a good thing.
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.
