Marine Geologist Marie Tharp: “The whole world was spread out before me, I had a blank canvas to fill with extraordinary possibilities” Marie, along with colleague Bruce Heezen, published the first complete world map of ocean floors. Their work helped prove the theory of plate tectonics, the idea that continents move over time.
