Coastal indigenous peoples consume nearly four times more seafood per capita than the world average and have strong cultural ties to the sea. Global ocean policies should preserve these connections.
People are more likely to support conservation for cute rather than creepy-looking animals.
One of the environmental legacies of the Obama administration is ocean reserves. Two ocean scientists explain why these are a critical but not sufficient piece of conservation.
Up to 236,000 tonnes of microplastic enter our oceans each year.
Plant-eating fish control the spread of seaweed and algae on coral reefs. New research explaining why populations of these fish vary from site to site could lead to better reef protection strategies.
Cool-water kelp forests are being eaten by tropical species moving south on warming waters.
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.
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.
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.
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.
