NASA's ocean floor map. Red areas are mountain and ridges, blue areas are canyon and trenches, by NASA Earth Observatory/Joshua Stevens
The bottom of the ocean is a mysterious place. We probably know the surface of Mars better than areas in the Atlantic and the Pacific. But we now have our best look at the seafloor yet, thanks to the NASA Earth Observatory.
The researchers looked at gravitational anomalies to produce a detailed analysis of underwater features, and by doing this were able to spot anything larger than 5 kilometers (3 miles).
