A 12-man Chinese team landed on the Antarctic icecap peak (南极冰盖最高点) on January 18th. They are the first people to reach the peak of Dome A (海穹A). It is 4,039 meters above sea level.
The team built a station there to study the changes of the weather, get ice samples (标本) from 150 meters to 200 meters below, and do other studies. So far, the team has got nearly 100-meter-long ice samples from a place about 130 meters under the icecap peak.
It is the first time that people have been able to get samples from the icecap peak in Antarctica and it is very important for people to study the weather changes and environment changes in the area.
The Chinese scientists have also built a weather study system (系统) at the peak. The system can send out information about the temperature, such as how strong the wind is, and many other things about the weather.
The Antarctica icecap makes up (组成) 70% of the earth’s freshwater (淡水). By studying Dome A, scientists can get the lowest temperature of the earth and other information about the world’s weather changes. We can’t get this information from other places on the earth because Dome A is the best place for this kind of studies. So it is very important to land on the peak of Dome A.
