Soundscapes of coral reef ecosystems can recover quickly from severe weather events such as Hurricane Irma in 2017, according to a new study.

Human-created noise can disrupt the behavior, physiology, reproduction, and ecosystems of whales and other ocean life. It can even lead to death.

But these 'cold-water coral' are threatened by accelerating sea currents.

A new method works like a blood test to identify heat-stressed corals that need protection from warming ocean waters linked to climate change.

Humans have caused ecosystems to collapse on purpose for millennia, to grow food or build settlements. But unplanned collapses are a different matter.

Standing 500m (1,640ft) tall, the "blade-like" reef was found off Australia's far north.

Charles Darwin's theory about the formation of atolls is elegant, but doesn't reflect key information: sea level. Researchers now correct his work.

Marine wildlife rarely remain in one habitat. Most species rely on a healthy network of ecosystems to raise their young and catch their food.

Sexual reproduction helps keep coral colonies diverse and resilient. Now, scientists are doing it in a lab to restock flagging reefs.

MV Wakashio ran aground on coral reef on 25 July and is now leaking oil.
