Study on the global environmental change with the various time scales by the various analysis of ice cores

在南极洲的Dome Fuji站钻取了一个深度为3035米的冰芯。冰芯记录了72万年前的全球环境变化。冰芯的年龄得到了很高的准确性估计，并很快出版了全球气候和环境变化的标准记录。此外，还开展了一项关于全球环境变化机制的研究。结果表明，在冰期-间冰期，硫酸盐气溶胶对温度变化有贡献。此外，我们还澄清了硫酸盐的来源不仅是海洋生物活动，还包括尘埃。

An ice core was drilled to a depth of 3035 m at the Dome Fuji station in Antarctica. Ice cores contain records of global environmental changes dating back to 720,000 years into the past. The age of the ice core was estimated with high accuracy, and a global standard record of climate and environmental changes was soon published. Further, a study of the mechanism of global environmental changes was developed. Results indicate that sulfate aerosol contributed to temperature change during the glacial-interglacial period. In addition, we clarified that the origin of the sulfate was not only the sea biological activity but also dust.
