Microstructural Location and Composition of Impurities in Polar Ice Cores

Abstract: This data set contains measurements of impurities and ions in three polar ice cores: the Vostok 5G ice core and the Byrd ice core from Antarctica, and the Greenland Ice Sheet Project 2 (GISP2) D core. Parameters include sample depth, grain size, ion concentration, and ice core impurity information. Measurements were made using Ion Chromatography (IC), optical microscopy, and Scanning Electron Microscope-Energy Dispersive Spectroscopy (SEM/EDS). Data are available via FTP in Microsoft Excel (.xls)and Microsoft Word (.doc) formats.摘要：本数据集收录了三根极地冰芯的杂质与离子测量数据，分别为南极的沃斯托克5G（Vostok 5G）冰芯、伯德（Byrd）冰芯，以及格陵兰冰芯计划2（Greenland Ice Sheet Project 2, GISP2）D冰芯。所记录的参数涵盖样品深度、晶粒尺寸、离子浓度及冰芯杂质相关信息。本次测量采用离子色谱法（Ion Chromatography, IC）、光学显微镜法以及扫描电子显微镜-能量色散光谱法（Scanning Electron Microscope-Energy Dispersive Spectroscopy, SEM/EDS）完成。 数据集可通过文件传输协议（File Transfer Protocol, FTP）获取，格式为Microsoft Excel（.xls）与Microsoft Word（.doc）文件。
