China-US Glacier Expedition Completes

A China-US joint Tibet glacier expedition that had lasted for more than 30 days called a complete success on September 11, 2004. Covering a journey as long as 3,000 km, the expedition has made comprehensive investigations in glaciers, lakes and atmosphere over the Qinghai-Tibet Plateau. Scientists analyzed the changes that have undergone or are undergoing under the impacts of global change. The systematic and factual investigations of the glaciers in the Ximalaya and Gangdise mountain ranges have revealed different types of glaciers, and confirmed the fact that plateau glaciers in Asia, with the Qinghai-Tibet plateau glacier as a typical case, have seen an allround shrinkage at an unprecedented speed.

Scientists’ study tour through the Namunani Glaciers has discovered that the glaciers, with a thickness of more than 200m, makes the thickest mountain glaciers so far found in the country. The increasing ice melting activities in the area has threatened the glaciers, desirable for extracting ice cores that contain historical climate data. Scientists, during the expedition, studied glaciers’ matter balance, glacier meteorology and hydrology, plateau atmospheric chemistry and the Quaternary period. Scientists analyzed, using a 6-m long ice core, climate changes recorded by the Namunani Glaciers, including variations in atmospheric elements, circulations, and microbes. The study is of important value to revealing the changes of past climate in the region, variations of Indian monsoons, and verifying the impacts of industrial pollutions from the southern Asia continent on the Qinghai-Tibet Plateau. The study is also valuable for studying global climate change and the impacts of human activities on climate.

Scientists also made extensive investigations of the lakes over the west part of the Qinghai-Tibet Plateau, as well as a lengthy tour over the Namucuo in the north of the Plateau, and Mapangyongcuo, in the west. The investigations turn out that the Plateau’s lakes have generally experienced shrinkage in terms of the total water surface.  However, a few exceptional lakes, with large glaciers sitting in their upper reaches, have seen some increase of water surface, possibly caused by the increased water supply by the glacier melting, which is more than the evaporation caused by climate change. To study the plateau’s energy and water cycles under global warming, scientists installed numerous observational instruments over the Plateau’s northern, middle and southern sections. The preliminary findings of observations show that both the plateau’s surface and air temperatures have gone up.

China-Japan Tibet Expedition Completes

Chinese and Japanese scientists have eventually put an end to their expedition tour through the northern section of Tibet, after more than 30 days’ arduous explorations. Scientists deployed, along the 1000-km long Qinghai-Tibet highway and Tanggulashan and Nianqing Tanggulashan mountain areas, 9 automatic weather stations, 1 boundary layer tower and radiation observation station, 9 deep soil temperature and moisture station, 2 multidisciplinary observation station including atmosphere and soil, 1 wind profiler, 2 atmospheric turbulence observation towers, and 1 laser radar. These facilities have collected extremely precious data on air, soil and ecology.

The data collected through the expedition has a great value for studying the atmospheric and ecological processes of the Qinghai-Tibet Plateau, the plateau’s special boundary layer structures, and energy and water circulation process. The data will also help scientists better understand the role of the Qinghai-Tibet Plateau in global climate change, and in producing severe weathers in the country.
