The Great Barrier Reef has been having a rough year. Warm waters have led to record coral bleaching this year and could hasten the reef’s die-off. But while surface corals are suffering, nearly a mile beneath the surface, deep-sea corals near the Great Barrier Reef are thriving.

An ambitious project to chart the seabed by 2030 could help countries prepare for tsunamis, protect marine habitats and monitor deep-sea mining. But the challenge is unprecedented

Explosive volcanic eruptions are possible deep down in the sea — although the water masses exert enormous pressure there. An international team reports in the journal Nature Geoscience how this can happen.

In the depths of the water just west of Greenland, scientists have discovered a previously unknown coral garden. They described the ecosystem in a new study published in Frontiers in Marine Science on Monday.

What lies off Australia’s Great Barrier Reef, in the Coral Sea? The region was mostly unexplored and uncharted until a recent expedition searched its dark waters, uncovering an abundance of life, weird geologic features and spectacular deep corals. The deepest forays reached down more than a mile.

In 2007, Bruce Robison’s robot submarine stumbled across an octopus settling in to brood her eggs. It seemed like a small moment. But as he went back to visit her, month after month, what began as a simple act of motherhood became a heroic feat that has never been equaled by any known species on Earth.

Living in an essentially zero-gravity environment, many deep-sea animals have evolved soft, gelatinous bodies and collect food using elaborate mucus filters. Until now, studying these delicate structures has been virtually impossible. A new study published in the journal Nature describes a unique laser-based system for constructing 3-D models of diaphanous marine animals and the mucus structures they secrete.

Explorers have captured video of the deepest-known octopus, revealing an adorably pudgy Dumbo octopus some 4.3 miles (6,957 meters) beneath the surface of the Indian Ocean swimming in what is called the hadal zone, where not even a drop of sunlight can penetrate.

Thanks to the Schmidt Ocean Institute, we’re getting a whole new perspective on life in the deep sea. After exploring the depths of the Indian Sea, they’ve released 4K footage of the Ningaloo Canyons. Located off the western coast of Australia, this previously unvisited area is the location of the institute’s latest expeditions—and the findings are incredible.
The canyons were visited by the ROV Sebastian, an underwater remotely operated vehicle which can go as far as 14,750 feet underwater. This far deeper than any human could ever dive, and the ROV can also stay at that depth far longer than any human-operated vehicle. Thanks to this technology, we’re able to stay on land and see the wonders far below the sea.

Even though the deeper layers of the ocean are warming at a slower pace than the surface, animals living in the deep ocean are more exposed to climate warming and will face increasing challenges to maintain their preferred thermal habitats in the future.
