During China’s 41st Antarctic expedition, researchers used self-developed equipment from Jilin University (JLU) to complete the country’s first ice sheet logging in East Antarctica's Larsemann Hills. The operation collected key data – including glacier temperature profiles and borehole orientation information – providing new insights into ice sheet dynamics.

Previously, during the 40th expedition, JLU's deep-ice drilling system retrieved 545 meters of continuous ice and bedrock cores. In collaboration with China University of Geosciences (Beijing) and Russian partners, JLU has twice obtained subglacial bedrock samples using domestically developed tools.

The two-month mission also recovered 7 cubic meters of drilling fluid, reflecting China's commitment to environmental protection. Located at the edge of the Princess Elizabeth Land ice sheet, the Larsemann Hills are crucial for understanding Antarctic ice flow and stability.

JLU has joined 10 Antarctic expeditions and led all of China's polar drilling projects, achieving multiple national and international firsts recognized by leading scientific journals.
