American geologist and marine cartographer Mary Sapp, who helped prove the theory of continental drift, is celebrated in the latest Google Doodle. On November 21, 1998, the Library of Congress named her one of the greatest cartographers of the 20th century.

Marie Tharp was born on July 30, 1920 in Ypsilanti, Michigan. Tharp’s father worked for the USDA and introduced her to cartography early on, reminding her of graffiti. She is pursuing a master’s degree in petroleum geology at the University of Michigan. In 1948, she moved to New York City and became the first woman to work at the Lamont Geological Observatory, where she met geologist Bruce Heezen.

“Heezen collected ocean depth data in the Atlantic Ocean, and Tharp used that data to map the mysterious seafloor. New discoveries from echosounders (sonar used to detect water depth) helped her discover the Mid-Atlantic Ridge. She brought these discoveries to the To Heezen, who infamously dismissed it as “girl talk,” Google says on its page dedicated to Tharpe. “However, when they compared these V-shaped rifts to maps of earthquake epicenters, Bruce · Heesen couldn’t ignore the facts. “

In 1957, Tharp and Heezen published the first map of the North Atlantic seafloor. Twenty years later, National Geographic published the first map of the entire underwater world by Tharp and Heezen, entitled “Under the World”.

In 1995, Tharp donated her entire map collection to the Library of Congress. In 2001, the Lamont Geological Observatory, where Tharp began her career, honored her with its first annual Lamont-Doherty Legacy Award.
