This map shows a global view of gravity changes. Shades of orange and red represent areas where seafloor gravity is stronger than the global average, a phenomenon that mostly coincides with the location of underwater ridges, seamounts, and the edges of Earth’s tectonic plates. Shades of blue represent areas of lower gravity, corresponding largely with the deepest troughs in the ocean
Daily Mail: The most accurate ocean floor map ever made: Scientists reveal the alien landscape beneath the sea in incredible detail

We have more complete maps of the surface of Mars than we do of some areas on Earth.
In an effort to change this, scientists have created the most detailed view of the Earth's seafloor to date, revealing huge mountains and giant crevices beneath the ocean.
The map was created by measuring the shape and gravity field of Earth, a relatively-new discipline known as geodesy. It provides gives an accurate picture of seafloor topography at a scale of 3.1 miles (5km) per pixel.
