Bedrock topography refers to the natural features and unevenness on the surface of solid rock beneath the soil and other layers. It helps us understand the bumps, holes, and shapes of the land that are formed by the underlying rock. Full definition
Using all available geologic, tectonic and geothermal heat flux data for Greenland — along with geothermal heat flux data from around the globe — the team deployed a machine learning approach that predicts geothermal heat flux values under the ice sheet throughout Greenland based on 22 geologic variables such as bedrock topography, crustal thickness, magnetic anomalies, rock types and proximity to features like trenches, ridges, young rifts, volcanoes and hot spots.
