In the latest map, as many as 20,000 previously unknown seamounts, between 1.5 and 2 kilometres high, pop into view scattered along relatively young sections of the sea floor, says Sandwell.

Accessing two previously untapped streams of satellite data, scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues have created a new map of the world’s seafloor, ...

The new map also provides details on thousands of undersea mountains, or seamounts, rising 1.6 kilometres or more from the sea floor, the researchers said. Some are covered by many kilometres of ...

New seafloor maps reveal the first clear view of a system of channels that may be helping to hasten the demise of West Antarctica’s vulnerable Thwaites Glacier. The channels are deeper and more ...

Accurate seafloor maps are also important for an improved understanding of deep-sea currents and tides, which affect life in the abyss, as well as geologic processes like plate tectonics.

Ocean explorers have long tried to chart the contours of the seafloor, but today's maps still pale in comparison to those of distant planets.

Better seafloor maps help us with navigation and conservation, among many other uses. Some 10 million sq km (3.8 million sq miles) of new bathymetric (depth) data was added in the past year.
