In the ocean, phytoplankton helped by diazotrophs play an outstanding role in withdrawing CO₂ from the atmosphere. But climate change is disturbing this delicate balance.

Even within a species, animals will suffer climate change differently. For sharks, it pays to live in warmer waters.
China's signature foreign policy is controversial for lots of reasons. But the environmental damage potentially wrought by the project has received scant attention.
Marine fish could serve as a crucial global emergency food supply in times of crisis, if marine ecosystems were in a healthy state to start with.
Maerl beds are the coral reefs of the British Isles. But like their tropical counterparts, they're threatened by climate change.
Sexual reproduction helps keep coral colonies diverse and resilient. Now, scientists are doing it in a lab to restock flagging reefs.
Here's how microplastics from your clothes end up in the deep sea.
The surprise decision is an important win for many Australians, but reform of Australia's offshore petroleum laws is urgently required to protect marine environments.
Scientists are building up a picture of how much carbon can be taken out of the atmosphere and stored in coastal ecosystems.
Hundreds of thousands of lakes, rivers and streams in the Arctic exist only because of the permafrost that lies beneath them. The warming Arctic threatens to change that.
Shark fisheries in Indonesia are an important economic resource in several areas. Hence, stronger regulations are needed to prevent declines in shark population.
Although less well known than its cousins, coral reefs and mangroves, seagrass plays a crucial role in climate change mitigation.
Our study found that some individuals who previously participated in destructive fishing practices can transform into inspiring leaders and influence others to protect coral reefs.
Populations of plankton are in decline. If we push this critical foundation of the marine food chain to extinction, we could cripple ecosystems for millions of years.
Coastal communities are helping scientists understand the impacts of marine heatwaves — and find solutions.
When we build marinas, ports, jetties and coastal defences we introduce hard structures that weren’t there before, and which reduce the amount of sunlight hitting the water.
They swim, they eat, they multiply.
With strategic planning, the marine protected area network could be a third smaller, cost half as much, and still meet the international target of protecting 10% of every ecosystem.
Everyone knows the Great Barrier Reef is in peril. But a continent away, Western Australia's Shark Bay is also threatened by marine heatwaves that could alter this World Heritage ecosystem forever.
The sediments that accumulate beneath seagrass meadows can act as secure vaults for shipwrecks and other precious artefacts, by stopping water and oxygen from damaging the delicate timbers.
