Ocean

A team of scientists from three notable oceanographic institutions has discovered the largest-ever aggregations of fish to be seen in the abyssal deep-sea region of between 9,800 and 19,600 feet beneath the ocean surface.

With the world continuing to warm and sea levels continuing to rise, NASA and the ESA are eyeing the next decade of climate change and its consequences, launching a new satellite to observe the ocean in greater detail from orbit.

When natural ocean shoreline is replaced by an artificial seawall, a lot of precious intertidal habitat is lost. A new study, however, indicates that by covering those walls with specially designed tiles, a substitute habitat can be created.

Scientists exploring the Great Barrier Reef have discovered a huge, never-before-seen coral reef, taller than the Empire State Building. Standing detached, the massive structure is the first new reef to be discovered in the area in over 120 years.

The cutting-edge polar research ship the RRS Sir David Attenborough – otherwise known as "Boaty McBoatface" – has finally set sail from its shipyard. It will now be put through trials before being officially handed over for service later this year.

From a record number of submissions, the 16th Through Your Lens photo contest delivers a world-class selection of the best underwater photography, from an incredible look inside a whale shark’s mouth to an amusing portrait of a smiling porcupine fish.

Coral bleaching occurs when corals are stressed by high water temperatures and other factors, causing them to expel the symbiotic algae living within them. Given that fact, scientists are now looking into saving reefs by pumping up cool water from the ocean's depths.

On the 400th anniversary of the start of an epic voyage from England to the New World aboard the Mayflower, an autonomous, solar-powered marine research vessel is due to launch on a mission to gather environmental data about the ocean.

Scientists studying more than half a century of data on bottom-dwelling shellfish have uncovered evidence of a feedback loop in which generations of these marine creatures are becoming trapped in warmer areas that threaten their survival.

While we hear a great deal about the huge patches of garbage that are floating on the world's oceans, there's even more trash lying on the seabed. The European Union-funded SeaClear project aims to gather much of it up, using autonomous robots.

Scientists in Australia have turned their attention to what human development means for the world’s marine environments, calculating the extent of our construction footprint on the oceans for the first time ever.

All kinds of fascinating discoveries are waiting in the deep sea. Now scientists have pulled a new monster out of the waters off the Indonesian coast. The creature is a new species of “supergiant” isopod, a huge marine relative of the common pillbug.
