New Delhi: Today’s Google Doodle celebrates the life of Marie Tharp, an American geologist and oceanographic cartographer who helped prove the theories of continental drift. He co-published the first world map of sea level. On this day in 1998, the Library of Congress named Tharp one of the greatest cartographers of the 20th century.

Mary Tharp was born on July 30, 1920 in Ypsilanti, Michigan. Mary Tharp’s father, who worked for the US Department of Agriculture, gave her an early introduction to mapmaking. She attended the University of Michigan for her master’s degree in petroleum geology – this was particularly influential as very few women worked in science during this period. She moved to New York City in 1948 and became the first woman to work at the Lamont Geological Observatory where she met geologist Bruce Hazen.

Bruce Hagen collected ocean-depth data in the Atlantic Ocean, which Tharp used to create maps of the mysterious ocean floor. New findings from echo sounders (sonars used to detect the depth of water) helped him discover the Mid-Atlantic Ridge. She brought these findings to Hazen, who denounced it as “girl talk”.

However, when he compared these V-shaped cracks with a map of the earthquake’s epicenter, Hagen could not ignore the facts. Plate tectonics and continental drift were no longer just theories—the ocean floor was undoubtedly spreading. In 1957, Mary Tharp and Hazen measured sea level in the North Atlantic. In 1995, Tharp donated her entire map collection to the Library of Congress. In 2001, the Lamont Geological Observatory, where Tharp had started her career, awarded her with its first annual Lamont-Doherty Heritage Award.
