Show Notes
In this episode of pplpod, we explore the life of Marie Tharp, the pioneering geologist and cartographer whose work fundamentally changed our understanding of Earth. Despite being barred from working on research ships due to her gender, Tharp used data collected by others to co-produce the first scientific map of the Atlantic Ocean floor in the 1950s.
We discuss her groundbreaking discovery of the Mid-Atlantic Ridge and the rift valley, which provided crucial evidence for the controversial theories of plate tectonics and continental drift. We also cover her complex partnership with geologist Bruce Heezen, who famously dismissed her initial findings as "girl talk" before earthquake data proved her right. Join us to learn how Tharp overcame sexism in science to map the unseen world beneath the waves.
