Oceanic cartographer Marie Tharp helped prove the theory of continental drift with her detailed maps of the ocean floor. This animation by Rosanna Wan for the Royal Institution tells the fascinating story of Tharp’s groundbreaking work.

About National Geographic:
National Geographic is the world’s premium destination for science, exploration, and adventure. Through their world-class scientists, photographers, journalists, and filmmakers, Nat Geo gets you closer to the stories that matter and past the edge of what’s possible.

In the early part of the 20th century, German geophysicist Alfred Wegener proposed a revolutionary idea that made him the laughingstock of his peers. His “continental displacement” theory suggested that the earth’s continents once formed a single land mass that had gradually drifted apart over time. Wegener was largely disregarded by the geoscientific community until 1953, when a young cartographer named Marie Tharp began charting ocean floor depth measurements. In partnership with geologist Bruce Heezen, Tharp’s detailed maps of the ocean floor revealed rifts and valleys that supported Wegener’s controversial theory. Initially dismissed as “girl talk,” Tharp and Heezen finally brought the concept of plate tectonics to the mainstream in 1968 when they published their ocean floor map in National Geographic Magazine. Cementing her place in history, Tharp was awarded the National Geographic Society’s Hubbard Medal in 1978 for her pioneering research.

This animation by Rosanna Wan for the Royal Institution tells the fascinating story of Marie Tharp’s groundbreaking work to help prove Wegener’s theory.

  1. Maybe it's unrelated but to make 2d animations like this do people mostly use adobe flash or other programs? and do you think the jitter effect is made with adobe after effects or from the flash?

    beginner here ^^ sorry

  2. You know what's heroic? What's commendable and beautiful? The concentration and determination Marie had to posses in order to work through the piles and piles of data, facing constant opposition and in return hearing the feedback that her research wasn't as valid because of her gender. We need more women in science.

  3. Fascinating presentation. I was a student assistant d;uring the International Geophysical year about 1957 or 58 when Buce Hezen was chief scienstist aboard the M/V Theta when the Theta and the R/V Vema were doing this maping of the middatlantic trench as it was already named at that time. Any questions I was there at Lamont Observitory doing the grunt work on this project

  4. Umm. The German wasn't absolutely right. For one thing the Earth is not completely molten inside, or at least not enough to initiate plate tectonic activity, which in and of itself is impossible. A solid granite crust cannot sub-duct, and in order for plates to move around propelled by convective currents in a molten interior, the surface would be far to hot to sustain life.

    Continental drift is a correct assumption. The reality here is that it was driven suddenly by a process called plate hydrology, best encapsulated by Walt Brown's Hydroplate Theory.
