NASA Scientist Reveals Details of Icy Greenland’s Heated Geologic Past
01 August 2018
By mapping the heat escaping from below the Greenland Ice Sheet, a NASA scientist has sharpened our understanding of the dynamics that dominate and shape terrestrial planets.
Dr. Yasmina M. Martos, a planetary scientist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, mined publicly available magnetic field, gravity and other geologic information for clues about the amount and distribution of heat beneath the portion of the North American continent that is Greenland.
Her resulting heat map exposed a thermal track beneath Greenland that records the movement of a continent through Earth's history.
