Solving the puzzle under the sea / Burleigh, Robert

Presents the life of the scientist responsible for the first map of the ocean floor, describing her experiences with sexism and her pioneering work which led to the confirmation of the theory of continental drift.

Marie Tharp always loved maps. Traveling with her father to make surveys, she felt like maps talked to her. Then in college, a teacher pointed out that though the oceans cover more than half the earth's surface, scientists knew very little about the bottom of the seas. She wondered, how deep are the oceans? Is the seafloor flat or are there mountains on the ocean floor?.
