Summary In summer 2019, scientists from the Technical University of Denmark, Stanford University and the Geological Survey of Denmark and Greenland scanned the DTU archives of ice-penetrating radar data. Our work will make it possible to analyse the data using modern-day techniques. In this project, we will continue our work digitizing and analysing this important dataset. The data contains information on the recent past of the Greenland ice sheet, and they can tell us more about the state of the ice sheet in the 1970s. This will help us understand the present state of the Greenland ice sheet, and how it will respond to a warmer climate in the future.
