Soft coral species in the deep sea exhibit bioluminescence, which researchers studied using remote-controlled underwater rovers. Many animals can glow in the dark.

NPR's Scott Detrow talks with Temple University biology professor Erik Cordes about the discovery of the world's largest known deep-sea coral habitat.

Corals searching for food in the cold and dark waters of the deep sea are building higher and higher mountains to get closer to the source of their food. But in doing so, they may find themselves ...

Mining conducted on the floors of deep seas could create "dark oxygen" containing metals that could impact the quality of oxygen above water.

It's hard to imagine a coral reef this size going largely undetected until now, but it's a sign of just how much of the ocean remains unmapped.

An underwater volcano near Tonga revealed how sediment spreads, disrupts marine life, and raises questions about deep-sea ...

Mining conducted on the floors of deep seas could create "dark oxygen" containing metals that could impact the quality of oxygen above water.

Deep below the surface of the ocean, bacteria and critters that feed off nutrients spouting from hydrothermal vents met with ...

When we think of the ocean, what often comes to mind are familiar sights– coral reefs, fishing boats, and waves breaking along the shore. But just a few hundred metres below the surface, the ...

The assumption is that [ocean] currents are better for deep-sea coral diversity. On the equator, there are complex current systems that change at different depths and vary dramatically in ...

Scientists mapped the largest deep-sea coral reef, which stretches over millions of acres off the Atlantic from Florida to South Carolina and is bigger than Vermont, according to the news release ...
