The longest underwater mountain range in the world
American geologist Bruce Heezer and oceanic cartographer Marie Tharp were researchers at the Lamont–Doherty Earth Observatory at Columbia University, New York. In the 1950s, they expedited with a crew across the Atlantic to gather data about the ocean floor from the ocean surface. The observations proved that there was in fact a chain of mountains, as high as halfway till the surface, under the ocean. They named it Mid-Atlantic Ridge, also known as MAR.
