What will it take to bring Australia’s lost coastal ecosystems back from the brink?

Australia's coastal and marine ecosystems have suffered death from a thousand cuts. But scientists say it’s possible to bring them back from the brink – if we act now.

A predicted ocean

Predicting the ocean requires mind-boggling technology, from salty robotic drifters and pristine supercomputers. But when it comes to the crunch, what is the first step?

The old age story of bigeye tuna in the western Pacific

New methods for estimating fish ages show smaller but long-lived bigeye tuna are part of a sustainable fishery in the western Pacific Ocean.

Climate change attribution – calculating the role of climate change in natural disasters

When a natural disaster occurs, scientists often get asked ‘how did climate change contribute?’. Modelling and data analysis are helping answer this, and other questions about frequency and severity of extremes.

Can we have healthy marine ecosystems and modify rivers in northern Australia?

We’ve used a novel ecosystem modelling approach to demonstrate how river flows are the lifeblood of marine ecosystems in the Gulf of Carpentaria.

Worldwide trawling impact revealed

Hidden beneath the waves, the impact of bottom trawling is often talked about but rarely properly understood. A recent CSIRO-led study has quantified that impact on a worldwide scale.

The state of ocean acidification

Ocean acidification is often thought of as a future impact of our changing climate. But exactly what is it, what are its impacts and is it really a problem of the future?

Reflections on the first national-scale snapshot of Indigenous engagement in marine science

Engagement of Aboriginal and Torres Strait Islander people in marine research can deliver mutual benefits for researchers and Indigenous people. A new survey has investigated scientists’ motivations, perceptions and practices for engaging Traditional Owners.

Shifting focus: The impacts of sustainable seafood certification

How a market-based mechanism designed to recognise and reward sustainable fishing practices captures social benefits; a case study of the Marine Stewardship Council’s Fisheries Standard applied in Western Australia.
