NASA discovered that there was a special heat source beneath the Marie Byrd ice sheet in southwest Antarctica to accelerate its melting

Antarctica is a strange place. Scientists have long studied the secrets of their huge ice sheets and Antarctic ice sheets, hoping to understand the unique geological features of the continent, but are often confused by new discoveries. Now, one of the puzzles that scientists have been puzzling for a long time may eventually have an answer, and it all starts with the surface.

The mantle plume is the heat generated by the earth's interior, pushing through the fissures of other fissures closer to the surface of the earth, which is believed to be responsible for the huge flow of underwater lakes and ice sheets. Because geothermal activity is not constant, this in turn affects the height above the ice sheet.


NASA's Jet Propulsion Laboratory is able to solve the mystery by establishing a plume data model, this model is based on the observation of the Yellowstone National Park geothermal activity, Yellowstone National Park there is a super volcano. The researchers used this model to prove that the underground heat source may be the cause of visible changes on the ice sheet surface.

This study will contribute to a better understanding of the region, and may help to predict future changes in Antarctic geomorphology. Scientists often study glacier retreat in Antarctica, as a potential indicator of how global warming affects current and future sea levels.
