Marie Tharp , a geologist and oceanographer, created maps that changed the way people imagine two-thirds of the world.

Her images were critical to the development of plate tectonic theory.

The seafloor provides habitat for fish, corals and complex communities of microbes, crustaceans and other organisms.

Tharp identified mountains and a rift valley in the center of the Atlantic Ocean .

In 1959 the Geological Society of America published “ The Floors of the Oceans: I. The North Atlantic” by Heezen , Tharp and “ Doc” Ewing .

Some scientists thought the work was brilliant, but most didn’t believe it.

French undersea explorer Jacques Cousteau was determined to prove Tharp wrong.
