Why did I love this book?
Until the mid-20th century it was largely assumed that nothing interesting lay on the bottom of the ocean floor.
Enter Marie Tharp, whose pioneering work mapping the records of soundings (sonar pings) laid the groundwork—literally—for our modern understanding of how the world’s continents and oceans are put together. Hali Felt’s biography of Tharp restores her to her rightful place in science history. I enjoyed, especially, the artistry involved in Tharp’s maps, which complied data from ocean expeditions that Tharp herself, as a woman, wasn’t allowed to join.
And, as a fan of geology, I was fascinated by Felt’s descriptions of how our modern understanding of continental drift and tectonic plates evolved from Tharp’s work.
