Marie Tharp and Mapping the Ocean Floor

As an oceanographic cartographer, Marie Tharp is credited with scientifically mapping the ocean floor in partnership with her colleague Bruce Heezen. Tharp and Heezen’s work was revolutionary, in that led to many discoveries and the theories of continental drift of plate tectonics. Tharp was a pioneer in science both as a woman and for her mapmaking.
