Covering Dagu glacier


On October 17, the results of a two-month “blanket” experiment on Glacier No. 17 of Dagu glacier revealed that the melting speed of ice body in the “covered” area was significantly reduced. Compared with the ice body in the uncovered area, the ice body could slow down the melting thickness of glacier by 1 meter, and it was preliminarily estimated that the melting rate of glacier could be reduced by about 70%.
Since August this year, Dagu glacier Scenic Area Administration and the cryosphere Laboratory of the Chinese Academy of Sciences jointly carried out the first “Application of geoengineering” measures to slow down glacier melting in China. The State Key Laboratory of Cryosphere science, Northwest Institute of ecological environment and resources, Chinese Academy of Sciences, has set up a 500 square meter experimental site at an altitude of 5000 meters on glacier 17 of Dagu glacier. A layer of geotextile with thickness of 5mm or 8mm is laid on the ice surface, which is like covering the glacier with a quilt. The experimental results show that this method can effectively slow down the glacier melting.
