Seamounts generally form when volcanic mountains rise up from the seafloor but fail to reach the surface (those that break ...

The disappearance of a tectonic plate into Earth’s interior may be responsible for the distinctive bend in the chain of underwater mountains and islands that includes the Hawaiian archipelago. A ...

Some 1,400 kilometers off the coast of Chile, rare deep-sea creatures drift along a garden of sponges and corals that grow along the flanks of a 3,100-meter-tall undersea mountain. A monthlong survey ...

The South Pacific Regional Fisheries Management Organisation (SPRFMO) is an intergovernmental body that regulates fishing across the vast international waters of the South Pacific Ocean. At a meeting ...

A new high-resolution simulation of Earth’s interior is reshaping how scientists explain the origin of tens of thousands of underwater mountains on the ocean floor. The model reconstructs 270 million ...

They’re less well known than Cook, Magellan and Champlain, but Tammy Norgard and her fellow scientists at Canada’s Department of Fisheries and Oceans are just as deserving of the title of explorer. In ...

The islands of Fiji and Vanuatu rise from the tropical waters of the South Pacific in one of the most tectonically active and geologically complex regions of the world. A new study of volcanism in ...

Naoki Saito, a researcher at the Integrated Research Center for Nature Positive Technology of the National Institute of Advanced Industrial Science and Technology (AIST) (and who is also affiliated ...

The deep seafloor, far from being a smooth muddy plain, is home to a large number of undersea mountains. By definition seamounts are geological structures more than 1,000 meters (3,300 feet) high, but ...

On September 6th, an international team of researchers assembled to survey deep-sea coral and sponge habitats on seamounts 300 miles offshore of the U.S.-Canada border in the Northeast Pacific Ocean.
