The ice core, with its strong fidelity, high information content, excellent resolution, and extended timescale, offers numerous advantages, is widely used in the study of the interaction mechanisms between the cryosphere and the global climate system. Ice core research has become a very important field for reconstructing the ancient climate and environment of the Earth, monitoring modern climate and environment, and predicting future climate and environment changes. Using ice core physical and chemical research methods, through ice core dating, isotope, gas, black carbon, volcanic ash, ions and dust particles and other continuous flow analysis, to explore the dynamic characteristics of the ice cap grain growth, to establish the evolution of polar ice microstructure and mechanism, to grasp the law of global climate change, to predict the dynamics of the glacier's response to the dynamic climate change and the trend of sea level rise and other factors of influence on the survival of mankind are of great significance. In addition, the mechanical properties of ice are of great significance to the research in the fields of glaciology, ice engineering, planetology, and material science.

        The Polar Research Center, Collage of Construction Engineering, Jilin University, utilized its independently developed core drilling equipment for coreless drilling of bedrock under deep polar ice to obtain two penetrating ice cores at Dalke Glacier, Zhongshan Station, Antarctica in 2019 and 2024, with a cumulative ice core length of 743 m. For this purpose, the center has established the Ice Coring Science Laboratory and the Laboratory of Ice Mechanical Properties.

      The Polar Ice Core Science Laboratory adheres to the scientific research concept of “focusing on the frontier, common orientation, and cross-fertilization”, and takes ice core, microorganisms, under-ice bedrock, under-ice hydrological environment, as well as polar exploration and observation technology and low-temperature engineering materials as the research objects to build a multidisciplinary and cross-internationalized scientific laboratory. Currently, research is mainly carried out on ice core ice microdynamics, biodiversity and function of polar microorganisms, identification of ancient Antarctic crust and land cores, metamorphic P-T evolution and tectonics, physical and chemical properties and migration of water in subglacial lake systems, polar geophysical ground-space/aerospace electromagnetic and seismic detection technologies, and lightweight advanced metal matrix composites under extreme conditions. The laboratory covers an area of about 500㎡, with functional areas such as a cryogenic ice physics laboratory (-18°C), an ice chemistry laboratory, a hydrology laboratory, a geology laboratory, a cryogenic sample library (-30°C), and a conference room. The laboratory is equipped with ice core cross-cutting according and vertical band saw, large-area scanning microscope, ice sample slicer and imaging table, ice core dielectric profiling test platform (DEP), DC conductivity tester (ECM), ice hardness tester and Fibre Bragg Grating Dynamic Acoustic Wave Detection (FBG) system, ultrapure water machine, ion chromatography analyzer, which allows the long-time storage of the ice cores, the cutting pre-processing and the production of the slices, and the physical mechanical parameters such as apparent characteristics, conductivity, capacitance, hardness, modulus of elasticity, dynamic viscosity, coefficient of internal friction and other chemical parameters such as anion and cation concentration of ice cores were tested. The ice mechanical properties laboratory is equipped with 100kN creep tester, 30kN electric fatigue tester and -70℃ low-temperature environment box, which can test the creep properties, fatigue properties, compressive strength, flexural strength and other mechanical property parameters of ice.
