Greenland Geothermal Heat Flow Database and Map (Version 1)

12 May 2022

The authors assemble all available geothermal heat flow measurements collected in and around Greenland into a new database. They use this database of point measurements, in combination with other geophysical datasets, to model geothermal heat flow in and around Greenland. Their geothermal heat flow model is generally cooler than previous models of Greenland, especially in southern Greenland. It does not suggest any high geothermal heat flows resulting from Icelandic plume activity over 50 million years ago.
