| Research Abstract |
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.
