Deep in the ice sheet that covers Antarctica, there is a lot of water. This finding commends scientists and presents an untapped part of frozen countries, which could have an impact on the region as a result of climate change.
This is the first time that large amounts of fluid have been found in sediments beneath ice. In recent years, scientists have found that there are lakes and rivers flowing across the continent, but they have not seen groundwater before, according to this new study. published in the Journal of Science this week did.
According to Chloe Gustafson, lead researcher at the University of California, Los Angeles, In Antarctica there are 57 meters of potential sea level rise, Therefore, it is important for research to know the whole process of ice and water exchange on the continent and the ocean to better predict the future of the land. how.
The authors of the new study spent six weeks working on subterranean ice, reports CNN International. During this time, they used devices directly placed on the surface to perform a process called “magnetotelluric imaging”, which detects the difference in the amount of electromagnetic radiation produced by ice. solid, fresh water and salt water in the rocks and create a recipe from these. different materials.
The discoveries are huge proportions. From Chinese scientists, If groundwater could be pumped out of the rocks and brought to the surface, that water would form a lake between 220 and 820 meters deep.
“In the final stages, the water will rise to the middle of the Empire, at its deepest, there are almost two empires united, this is important because the lakes The depth of the subglacial area in the present area is 2 to 15 meters, which is only one to four floors of the Empire State. ”
The study indicates that sea water reaches the subterranean part of Antarctica during the warm season, which occurred between 5,000 and 7,000 years ago, saturating the sediment with salt water. As the ice rises, the fresh water formed by the pressure from above and the friction at the base of the ice is forced into the sediments above. And, according to scientists, it may still be filtered and mixed with groundwater even today.
