Marie Tharp


Marie Tharp (1920-2006), the eponym of the lecture series, was a pioneer of modern oceanography. Tharp was the first to map details of the ocean floor on a global scale (1977, Heezen-Tharp map). Her observations became crucial to the acceptance of the theories of plate tectonic and continental drift in Earth sciences. She was one of the first women in the academic world of geology, although she received official recognition only at the end of her career.

Marie Tharp Lecture Series for Ocean Research

The Marie Tharp Lecture Series aims at presenting high-profile female scientists in Marine Sciences as role-models for young scientists. In combination with a public lecture, there is a get-together exclusively for women to discuss career pathes and exchange experiences.

The next MTLS will be announced soon!
