Corals are comeback creatures. As the world froze and melted and sea levels rose and fell over 30,000 years, Australia’s Great Barrier Reef, which is roughly the size of Italy, died and revived five times. But now, thanks to human activity, corals face the most complex concoction of conditions t ...

Coral reefs around the world are under increasing stress due to a combination of local and global factors. As such, long-term investigation is becoming increasingly important to understanding ecosystem responses.
Most of the heat from global warming has gone into the oceans, so it is no wonder that the seas are experiencing massive heatwaves too. What's more, climate change is causing a fall in global ocean oxygen levels.
Scientists have seen for the first time how corals collaborate with other microscopic life to build and grow.A study led by The University of Queensland and James Cook University reveals at the DNA level how coral interacts with partners like algae and bacteria to share resources and build healt ...
The fate of the world's coastal regions and the hundreds of millions of people who inhabit them depend on a block of ice atop West Antarctica on track to lift global oceans by at least three metres.

As you’ve likely heard, the ocean’s health is in trouble. You’re probably aware of overfishing and the harmful practices of fisheries driving a third of the planet’s fish stocks toward extinction, and you surely know about the unconscionable amount of pollution, in particular plastic, that we du ...
