Sulfate-Based Volcanic Record from South Pole Ice Core, Version 1

This data set contains concentrations of soluble chemical species (ions) within a 120 m ice core retrieved at the South Pole station in 2001. The ice core was dated with annual resolution using annual layer counting. Investigators measured chemical species, ions, and volcanic deposits found in the cores. The analysis was conducted at South Dakota State University between 2001 and 2003. Data are available in Microsoft Excel or ASCII text format via FTP from NSIDC.

本数据集收录了2001年于南极科考站取回的120米冰芯内可溶性化学组分（离子）的浓度数据。该冰芯通过年层计数法确定年代，分辨率达年际尺度。研究人员对该冰芯中的化学组分、离子及火山沉积物开展了测定工作。相关分析于2001年至2003年间在南达科他州立大学完成。使用者可通过文件传输协议（FTP）从美国国家冰雪数据中心（NSIDC）获取该数据集，数据格式支持Microsoft Excel与ASCII文本两种。
