A recent study published in the journal Science Bulletin was led by Dr. Shugui Hou (Nanjing University and Shanghai Jiao Tong University) and Dr. Hongxi Pang (Nanjing University). Shugui Hou drilled an ice core with a length of 127.8 m from the Zangser Kangri (ZK) ice cap in the central Tibetan Plateau (TP) in April 2009. The ice core was not well dated until the development of 14C dating technique at the microgram level in glacier ice in the past decade.
