Work And Observations Of Marie Tharp

Marie Tharp was introduced to mapmaking by her father who worked for the US Department of Agriculture. A master in petroleum geology from the University of Michigan, Marie Tharp went to work at the Lamont Geology Observatory in 1948.

Marie Tharp produced maps of the mysterious ocean floor using the data gathered by Bruce Heezen. She developed the ocean-depth data of the Atlantic Ocean with echo sounders and took her findings of the Mid-Atlantic Range to Heezen who termed her work as “girl talk”. But Bruce Heezen had to accept the findings on comparing the V-shaped rifts with earthquake epicenter maps.

In 1957, Tharp and Heezen co-published the first map of the ocean floor in the North Atlantic. Later the map was published by National Geographic as “The World Ocean Floor”. She donated her map collection to the Library of Congress in 1995. The Lamont Geological Observatory awarded her with its first annual Lamont-Doherty Heritage Award in 2001.
