Today Google has prepared a doodle of American Geologist, Google is celebrating the life of American Geologist Mary Tharp through Doodle. Along with a geologist, he is also an oceanographic cartographer, who helped prove the theories of continental drift. He 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.
Born in 1920
Mary Tharp was born on July 30, 1920 in Ypsilanti, Michigan. Tharp’s father worked for the US Department of Agriculture and gave him an early introduction to mapmaking. He further attended the University of Michigan for a master’s degree in petroleum geology. 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 Hagen.
This is how the world map was made
Google explained through its search page, ‘Hazen 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 them discover the Mid-Atlantic Ridge.
Awarded in 2001
In 1957, Tharp and Hagen co-published the first map of sea level in the North Atlantic. Two decades later, National Geographic published the first world map of the entire ocean floor by Tharp and Hagen titled ‘The World Ocean Floor’. In 1995, Tharp donated his entire map collection to the Library of Congress. In 2001, the Lamont Geological Observatory, where Tharp began his career, honored him with its first annual Lamont-Doherty Heritage Award.
