Thousands of seabirds die every year from consuming plastic trash in the oceans. But why do they eat plastic? New research shows that it produces odors that help some species find prey.

Managing maritime security is a challenging endeavour. Forms of maritime crime include piracy, drug and arms smuggling.
They ‘engulf living prey, suck out their innards, poison them, harpoon them, make them explode, and steal and reuse body parts’. And we ignore them at our peril.
Warming waters due to climate change are losing oxygen, threatening the health of fish and ecosystems.
Poor management of the oceans, including the killing of crucial marine predators, could result in more greenhouse gasses.
Melanesia’s oceans are worth at least US$5.4 billion, but are under increasing threat.
Researchers ran computer simulations that take into account environmental variability and geographical setting to investigate how early explorers made it to these tiny, remote islands in the Pacific.
The increasing use of the sea for human activities has resulted in a dramatic rise in noise levels.
New South Wales wants to extend its shark net program after a spate of attacks in the north of state.
Seagrass is more than just a bit of sea greenery.
Technology had enabled humans to explore the deep sea, the Earth’s poles, and outer space. But we shouldn’t forget historical lessons about frontiers in the process of traversing them.
Laying the first telegraphy cable under the Atlantic was the Victorians’ version of the Apollo mission – it caught the imagination of a generation.
Most ocean species start out as larvae drifting with currents. Using underwater robots, scientists have found that larvae use swimming motions to affect their course and reach suitable places to grow.
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.
More of Australia’s oceans should be placed under high protection, according to the latest marine reserves review.
We tend to think of the oceans as quiet, when in fact they’re anything but. Noise is the “forgotten pollutant”, but the good news is that unlike many other pollutants it can be switched off if we try.
The Papahānaumokuākea Marine National Monument is huge win for preservation, but it also poses outsized management challenges for the National Park Service.
Marine parks need to cover large swathes of ocean, but they also need to cover the right areas if they are to deliver the best conservation. New research off Australia’s northwest suggests how.
Scientists are using detailed computer models of the ocean to trace debris back through the currents to the potential crash site.
Crime on the ocean is not only about illegal fishing – it ranges from drug smuggling to human trafficking and modern-day slavery as well.
