Topographic or satellite maps of Earth may reveal ridges and troughs that crisscross flat plains on the ocean floor, making it seem as though the entire ocean floor has been mapped out, Ferrini said.

Earth's oceans have topographic features and are held down by gravity, not contained by a giant Antarctic ice wall.

An ultra-detailed map of the ocean floor uses gravity-based data collected by satellite. NASA and CNES launched the satellite to survey Earth’s surface water.

World News Satellite launched to map the world’s oceans, lakes, rivers Nicknamed SWOT — short for Surface Water and Ocean Topography — the satellite is needed more than ever as climate ...

In the mid-20th century, when people looked at a map of the world, they saw the familiar continents surrounded by vast, featureless oceans. Beneath the waves, the ocean floor was largely unknown ...

The Texas Hill Country has been notorious for flash floods caused by the Guadalupe River. Here's why the area is called ...

NASA's Surface Water and Ocean Topography satellite, aka SWOT, has provided one of the most detailed maps of the seafloor ever created.

Scanning a whole area of the seafloor, then, will give you a depth — or bathymetry — map. In the same way that a topography map shows elevation changes, a bathymetry map shows changes in depth.

Scientists Create One of the Most Detailed Maps of the Ocean Floor, Find Close to 100,000 Submerged Mountains For decades, humanity has gazed at the stars, dreaming of Mars and the Moon, while a ...

A newly-deployed satellite has created the most-detailed map yet of the ocean floor, finding hundreds of hills and underwater volcanoes that were previously missed.

The crew of the E/V Nautilus has already spotted whale corpses, octopus gardens, and the wreckage of German submarines sitting on the ocean floor. There’s much more to see.
