MARIE THARP – The Woman Who Mapped the Ocean Floor

How One Brilliant Woman Mapped the Ocean Floor’s Secrets. Marie Tharp’s incredible maps were integral to the acceptance of the plate-tectonic theory.

Take a look at the map of the ocean floor. In the Atlantic Ocean, the continental shelf gives way to a steep descent into the the Hatteras Abyssal Plain, then it climbs back up at the Mid-Atlantic Ridge. Then the Pacific: therein lies the deepest part of the ocean, the Mariana Trench. The ocean floor has mountain ranges and valleys, just like dry land. And the map of these highs and lows also holds the key to plate tectonics — the theory that explains how continents move.
