| Research Abstract |
The aim of this research is to characterize the terrestrial climatic changes for three different spatial-scales of global, Asia, and East Asia. Major research subjects are as follows: (1) climate reconstruction in land region where enough climate change reconstruction is not done, (2) chronological matching among the records of climatic changes obtained from ocean, land and poles. The research has also developed the methods necessary for paleoenvironmental studies such as silicon and oxygen isotope analyses of the diatom fossil in lake sediment, the extraction method of the diatom fossil from the sediments and the isotope of lake sediment cellulose, which are thought to be effective as a climate change proxy. We have successfully developed new methods for determining the silicon and oxygen isotope changes of fossil diatom (laser- and batch methods), the carbon and radiocarbon isotope changes of lake sediment cellulose. These methods will be effective for investigating the terrestrial climatic changes. These R＆D will give the detailed information on terrestrial climatic changes for three different spatial-scales. It is remarked that the difference of the climate change pattern from the last glacial period to interglacial in the Atlantic Ocean region and the Pacific Ocean region were identified.
