Soundings: The Story of the Remarkable Woman Who Mapped the Ocean Floor: Felt, Hali: 9780805092158: Amazon.com: Books
Britt Peterson: Felt’s re-creation fills in a previously blank region of scientific history. Tharp was a strong-willed woman who used recorded soundings to map the ocean floor and change the course of ocean science. Hali Felt’s biography of Marie Tharp is a complex, rich biography of a groundbreaking geologist who discovered ‘a rift valley running down t
What is Marie Tharp famous for?
Tharp and Heezen published the first complete world map of the ocean floors in 1977, which helped to prove plate tectonics, the theory that continents move over time, which had been controversial until then. The discovery revolutionized our understanding of nearly everything on the planet.
What was Marie Tharp’s contribution to the discovery of plate tectonics?
That was the case in 1953, when a young geologist named Marie Tharp created a map that proved the controversial theory of plate tectonics. However, Tharp’s discovery of the 10,000-mile-long Mid-Atlantic Ridge*u2014 a find that revealed the sea floor was spreading u2014 was dismissed at the time as “girl talk.”
What did Marie Tharp do as a kid?
u201cAs a small child, she would sit in the back of her father’s truck’making mudpies and generally being a nuisance,u201d according to the Geological Society of America. He mapped soils in 14 states u2014 from New York to Florida, and west to Idaho u2014 and young Marie loved to go with him in his fieldwork.
Where did Marie Tharp go to college?
Marie Tharp and her research partner Bruce Heezen are credited with creating one of the world’s first comprehensive maps of the ocean floor, transforming a once barren and flat landscape into a dynamic three-dimensional space with mountains, valleys, and trenches.
What is Marie tharps middle name?
Marie Tharp (born 1920) is best known for her ocean floor maps.
What was discovered in 1953 using sonar?
Scientists discovered a prominent valley, known as the Great Global Rift, running down the center of these ridges in 1953, and Hess was intrigued enough to reexamine the data from a completely different, unconventional perspective.
How did Marie Tharp map the ocean floor?
Tharp used only pens, ink, and rulers to literally draw the underwater details of the ocean floor, longitude degree by longitude degree. Tharp used what is known as the physiographic mapping technique, which uses light and texture instead of color for her diagrams.
What did Marie discover that was the smoking gun for continental drift?
That symmetry was the proof that the theory of seafloor spreading was correct, and it set the stage for our current understanding of plate tectonics.
Is Marie Tharp still alive?
The Blackfeet call the Rocky Mountains “the Backbone of the Earth.”
When did Marie Tharp go to college?
After her father retired, the Tharps purchased a farm in Bellefontaine, Ohio, where she graduated from high school a few years later. After her mother died in 1936, she took a year off before going to college to help out with the farm, and she enrolled in the University of Ohio in 1939.
Who mapped out the ocean floor in 1952?
In 1952, Tharp and Heezen began mapping the individual ocean floors, but they ran into difficulties.
What type of science did Marie Tharp study?
Marie enrolled in a petroleum geology program, becoming one of the first “Petroleum Geology Girls” when she graduated in 1944. She worked in the petroleum industry for a short time but found it unfulfilling, so she returned to Tulsa University to resume her studies.
