Meet Marie Tharp (1920–2006), the first person to map the Earth’s underwater mountain ridge, in this inspiring picture book biography. From a young age, Marie Tharp loved watching the world. She loved solving problems. And she loved pushing the limits of what girls and women were expected to do and be.

“The ocean stretched out before her, like a big blue mystery.”

“Ocean Speaks: How Marie Tharp Revealed the Ocean’s Biggest Secret” is ritten by Jess Keating and illustrated by Katie Hickey. Published by Tundra Books in 2020. Bought thanks to a sold woven bookmark ❤️
