Is Australia meeting the UN recommendations for the Great Barrier Reef?

The government says it has met all of the recommendations for safeguarding the Great Barrier Reef. But a close reading of the dozens of UN recommendations shows that many have been only partly fulfilled.

Concrete coastlines: it’s time to tackle our marine ‘urban sprawl’

Urban sprawl has spread to the sea, as more and more man-made structures are being built along the world’s coastlines. Just as we do on land, we need to think about how to build sustainably at sea.

We are finally learning the Perth Canyon’s deep‑sea secrets

The Perth Canyon, off Australia’s west coast, is twice the size of the Grand Canyon. But only now, with the help of remote-controlled submarines, are researchers finding out what lives in its depths.

Ocean depths heating steadily despite global warming ‘pause’

The oceans are continuing to warm steadily despite an apparent slowdown in global warming at the earth’s surface, according to data collected by thousands of floating robots published today in Nature Climate…

Southern oceans heating up faster than scientists realised

The upper layers of the world’s oceans have been warming much faster than oceanographers realised over the past few decades, according to a new study. Sparse sampling of the Southern Hemisphere’s oceans…

Explainer: how weather can trigger dangerous tsunamis

At around 10pm on Sunday 17 August 2014, the container ship AAL Fremantle was being unloaded after arriving in Western Australia’s Fremantle Harbour, when it broke away from its mooring and collided with…

Marine science: challenges for a growing ‘blue economy’

In many ways, Australia is defined by the oceans surrounding us. We have the world’s third largest ocean territory, most of our trade travels by sea, and we have vast offshore resources.

The difficulty of searching for MH370 in a giant rubbish patch

Frustratingly, the search for missing Malaysia Airlines flight MH370 has turned up many floating objects, but none of them are from the plane. That’s largely because the latest search area is likely to…

Under the deep blue ocean: the search for MH370’s black box

As the effort to find Malaysian Airlines flight MH370 moves inexorably towards the recovery stage, the challenge of finding the plane’s flight recorder (called the “black box” even though it’s actually…

Recovering MH370 will be difficult in a complex, unforgiving ocean

It has been confirmed that the Malaysia Airlines plane that disappeared on March 8 crashed into the southern Indian Ocean. It would be hard to choose a more complicated region of the ocean to be searching…
