Vostok Ice Core Chemistry, Timescale, Isotope, and Temperature Data

This data set contains ice core chemistry, timescale, isotope, and temperature data analyzed by several investigators. In January 1998, the collaborative ice-drilling project between Russia, the United States, and France at the Russian Vostok station in East Antarctica yielded the deepest ice core ever recovered, reaching a depth of 3,623 m. Preliminary data indicate the Vostok ice-core record extends through four climate cycles, with ice slightly older than 400 kyr.本数据集收录了经多名科研人员分析得到的冰芯化学组分、年代标尺、同位素及温度数据。1998年1月，俄罗斯、美国与法国在南极东部俄罗斯沃斯托克（Vostok）站联合开展冰芯钻探项目，获取了迄今已回收的最深冰芯，钻探深度达3623米。初步数据显示，沃斯托克冰芯记录覆盖了四个气候周期，其封存冰体的年代略早于400 kyr。
