中国第35次南极科学考察(2018-2019年) 南极雪坑离子分析数据

可溶性离子可以用来区分和探明某些物质成分的来源、传输路径和沉积过程，从而利用冰芯记录恢复大气环境的历史，具有独特的优势和重要意义。通过对表层雪、雪坑样品的采集，对大气沉降物的雪冰化学成分及含量分析，研究其在冰盖表面的时空分布与变化特征，结合沉积区的地理、气象气候等特征，研究区域分异特点，探索在不同区域的物质来源，获得过去大气环境的历史记录，为进一步研究由冰雪地球化学参量反演的气候环境变化过程奠定基础。
本数据为中国第35次南极考察实地采集雪坑样品的离子分析检测数据，于2018年12月19日至2019年1月28日于中山站-Dome A之间选择点位，采集雪坑样品。
测量仪器名称：离子色谱仪，仪器型号：ICS-3000，精确度：测量范围0.01-15000uS，检测限：0.05mg/L, 相对标准偏差：<1%，标定方法：外标法。

Soluble ions can be used to distinguish and trace the sources, transport pathways and sedimentary processes of specific substances, thus enabling the reconstruction of historical atmospheric environments using ice core records and holding unique advantages and vital significance. By collecting surface snow and snow pit samples and analyzing the snow/ice chemical compositions and concentrations of atmospheric deposits, we can investigate the spatio-temporal distribution and variation characteristics of these components on the ice sheet surface. Combined with the geographical, meteorological and climatic features of the sedimentary regions, we can study regional differentiation characteristics, explore material sources in different areas, obtain historical records of past atmospheric environments, and lay a foundation for further research on climate and environmental change processes inverted from ice-snow geochemical parameters.
This dataset contains ion analysis and detection data from snow pit samples collected during China's 35th Antarctic Scientific Expedition. Snow pit samples were collected at selected sites between Zhongshan Station and Dome A from December 19, 2018 to January 28, 2019.
Measuring instrument: Ion chromatograph; Instrument model: ICS-3000; Measuring range: 0.01–15000 μS; Detection limit: 0.05 mg/L; Relative standard deviation: <1%; Calibration method: External standard method.
