The Great Barrier Reef might get all the attention, but what about our western coral reefs? Warmer waters and human impacts mean these reefs are in trouble.

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.
Microbes can act as canaries in the coalmine for ocean pollutants such as sewage.

There are more bacteria in the ocean than stars in the known universe. New genetic techniques are letting us use microbes as early warning systems for oceans in trouble from pollution and other stresses.
A new real-time measuring buoy can change the way the maritime industry operates.

The dust storm that turned Sydney red in 2009 triggered plankton blooms in the Tasman Sea, demonstrating how we might fertilise the ocean to take up more carbon dioxide.
Gamba Grass is altering fire regimes in the Top End, threatening human life and property, natural assets including Kakadu and Litchfield National Parks, and compromising savanna burning programs.

One of the Australian government’s new research priorities is “environmental change”. But can be hard to know how to tackle such huge and interlinked issues as climate change and species extinctions.
The reefs of Indonesia - part of the Coral Triangle - could lose many of their species thanks to climate change.

Over-fishing is a massive environmental and economic challenge. Fortunately, there are new solutions being trialled – including in a tuna hotspot in the Pacific.
Expect to see more ships on the horizon, as global shipping booms. But how well are we measuring and governing what happens at sea?

As the world’s land-based economies struggle with around 2% GDP growth, the global marine economy – often talked about as “the blue economy” – is a bright light on the horizon.
The Great Southern Reef is unique, beautiful and contributes significantly to Australia’s culture and economy. However, few of us realise the magnitude and value of this gem right at our doorstep.

A rash of white shark attacks this summer points to a rebounding population in the US – a sign of healthier oceans and the need to coexist with this apex predator.

To create accurate models that predict how ice sheets and oceans will react to changing climate, modelers need precise current data. One researcher heads to the ends of the earth to collect just that.
The Southern Ocean is remote, cloudy – and full of plankton.

Although frightening, the footage of Mick Fanning at Jeffreys Bay is a reminder that sharks are present in the oceans, and that the vast majority of interactions between people and sharks end without fatality or injury.
Sensationalized shark attacks skew the facts.

Millions tune in to Shark Week each year, but many walk away with the wrong impressions.
Acehnese fishers are among the quarter of the world’s population who live on the coast, and for whom climate-driven changes to the oceans would make life much harder.

Failing to stick to the world’s agreed global warming limit of 2C won’t just affect the atmosphere - it will play havoc with the oceans too, potentially ruining ecosystems on which much of humanity depends.
