Marie Tharp: Google Doodle celebrates life of American geologist Marie Tharp with creative doodle | World News


New Delhi: Doodle for today’s honor Mary TharpOne American geologist and oceanic cartographers who contributed to the validation of the continental drift hypothesis. He contributed to the first ocean floor map of the planet.
The Library of Congress recognized Tharp as one of the top cartographers of the 20th century on this day in 1998.
Google Doodle TODAY includes an interactive biography of Tharp.
Three prominent women who are actively carrying on Tharp’s legacy by making advances in the typically male-dominated fields of oceanography and geology provide detail for her story: Caitlin Larsen, Rebecca Nesseland dr. tiara moore,
Marie on July 30, 1920 TharpAn only child, Ypsilanti, was born in Michigan.
Mapmaking was introduced to Tharp by his father, who worked for the US Department of Agriculture.
She earned a master’s degree in petroleum geology at the University of Michigan, which was particularly notable given the paucity of women in science careers at the time.
She moved to New York City in 1948 and was the first female employee at the Lamont Geological Observatory, where she met geologist Bruce. Heizen,
According to Google, 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 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, Tharp and Hazen co-published the first map of sea level in the North Atlantic. Twenty years later, National Geographic published the first world map of the entire ocean floor authored by Tharp and Hagen, titled “The World Ocean Floor.”
Tharp donated his entire map collection to the Library of Congress in 1995. At the 100th anniversary celebration of its Geography and Maps Division, the Library of Congress named him one of the most important cartographers of the 20th century. In 2001, the same observatory where she began her career honored her with its first annual Lamont–Doherty Heritage Award.
