DAMXUNG, Tibet, Aug. 24 (Xinhua) -- Chinese scientists
will set up two seismic stations in Antarctica later this year to
measure tremors and tectonic movements on the continent, a geologist said on
Friday.
The two broadband seismic stations
will be installed at Eagle Camp, 806 kilometers from Zhongshan Station, one of
China's two permanent exploration stations, and Dome-A, the highest point on the
continent about 4,093 meters above sea level, said An Meijian, a researcher with
the Beijing-based Chinese Academy of Geological Sciences.
An and 16 other potential Antarctic explorers are
currently receiving a two-week field training program in Tibet that will prepare
them for China's 24th Antarctic expedition scheduled for October.
Upon their return from the expedition, An said they
would have extracted the first batch of surveillance data. Through an analysis
of the data, they would expect to work out seismic images of the crust and upper
mantle beneath the two observation sites, he said.
"We'll also refer to data obtained by international
scientists and work out a detailed tectonic map of the Antarctic icecap," he
said.
Worldwide scientists are increasingly keen on the
research into the tectonic movements of Antarctica, which used to be two plates
that pulled away from each other in the northern Ross Sea between 28 and 40
million years ago.
"The two plates have since solidified into one, which
is what confused geologists," said An.
The Chinese expedition team, consisting 219
explorers, will also fix the site of China's third scientific research station
at the South Pole, a planned observatory with seven telescopes and one acoustic
radar at Dome-A.
Construction of the new station is part of the
country's contribution to International Polar Year (IPY) 2007/2008, which runs
from March 1, 2007, to March 1, 2008.
The observatory will be used for scientific research
in summer but will eventually be developed into a permanent station capable of
accommodating scientific research all year round, said E Dongchen, director of
the Chinese Antarctic Center of Surveying and Mapping.
Scientists will install a wireless sensor network to
monitor Antarctic glacial changes, said Dr. Cheng Xiao, a remote sensing
specialist of the Chinese Academy of Sciences.
