Climate change will affect the nutrition of seaweeds eaten by billions of people around the world.
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.
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.
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.
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.
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.
