Qomolangma (Everest) since 1954 reveals a sharp decline in net-accumulation in the 1960s, and the annual net-accumulation during the 1970s to the beginning of the 1990s is only half of that at the end of the 1950s. The decreased net-accumulation is coincident with glacier retreat, which is associated with recent temperature increase in the region that intensified the ablation. Under the background of global warming, such glacier variation trends will aggravate.展开更多

In recent years, the glaciochemistry has been progressing rapidly. Soluble ions are the major impurity deposited on polar glaciers and also are an important aspect of glaciochemistry. Previous studies have covered several locations of Antarctica except the region around the Great Wall Station of China.展开更多
