The SWOT satellite can pick up seamounts less than half that height, potentially increasing the number of known seamounts from 44,000 to 100,000. These underwater mountains stick up into the water ...

A seamount nearly twice the height of the world’s tallest building has been discovered on the ocean floor near Guatemala — and serves as a biodiversity hot spot.

A team of oceanographers from the Scripps Institution of Oceanography, Chungnam National University, and the University of Hawaii have used radar satellite data to map 19,000 previously unknown ...

The number of known mountains in Earth’s oceans has roughly doubled. Global satellite observations have revealed nearly 20,000 previously unknown seamounts, researchers report in the April Earth ...

The four seamounts range in size from approximately 1,591 meters (5,220 feet) to 2,681 meters (8,796 feet). This revelation builds on a discovery made by the same crew last year.

Researchers found and mapped four seamounts in the deep sea off the coast of Peru and Chile. The tallest of these new peaks rises around 1.5 miles above the seafloor.

Surveyors map seamounts using one of two modes – echo sounders or multibeam sonar on ships for topographic mapping or using satellite altimetry for gravity-field mapping.

The seamounts range from 5,220 to 8,796 feet high and reign over a mysterious submerged world that is ... “Examining gravity anomalies is a fancy way of saying we looked for bumps on a map, ...

Older satellites have mapped large seamounts, but the team spotted thousands of smaller, previously unknown seamounts less than 3,300 feet (1,000 meters) tall in the SWOT data.

Oceanographers at Scripps Institution of Oceanography worked with researchers from Chungnam National University and the University of Hawaii to map 19,000 previously unknown seamounts around the ...
