Joe MacGregor on Mapping the Geology of Greenland Below the Ice
Manage episode 450064098 series 3293313
With most of Greenland buried by kilometers of ice, obtaining direct information about its geology is challenging. But we can learn a lot from measurements of the island’s geophysical properties — seismic, gravity, magnetic from airborne and satellite surveys and from its topography, which we can see relatively well through the ice using radar. In the podcast, Joe MacGregor explains how he created a new map of Greenland’s geology and speculates on what we can learn from it.
MacGregor is a Research Physical Scientist at NASA’s Goddard Space Flight Center.
