Scientists look into the ice age with 3D radar maps

As part of a NASA project called Icebridge, 3D maps of Greenland have been developed, allowing a glimpse into the distant past dating back to the ice age.

To create a map, scientists used data from a radar installed on an airplane. Large areas covered with ice were examined, which made it possible to determine how much the water level in the world's oceans would rise, if the ice melted - by more than 6 meters.

The map will also help to trace the history of ice cover formation and its evolution. It is no secret that over the past 20 years, due to the rise in the average temperature on Earth, the Greenland glaciers are rapidly melting. Studying ice structure will help researchers make predictions for the near future.

A special ice radar - CReSIS makes it possible to penetrate into the glacier and do layer-by-layer analysis, as in the study of an ice core. In addition to research on snow and ice temperature, various impurities in the snow are being studied - dust and volcanic deposits that have accumulated there over hundreds of thousands of years. Scientists are especially interested in the ice of the Eem period, which appeared about 115-130 thousand years ago.
