| Research Abstract |
In order to reconstruct paleoclimatic changes quantitatively during the last 400,000 years in and around Lake Biwa, four short cores were recovered from lake bottom surface and correlation between proxies of sediment and equipment data were examined. Proxies of sediment were obtained by determination of sedimentary age using lead-210 method and several kinds of analytical data at each depth. Meteorological data were based on those of Hikone meteorological observatory. Good correlation existed between density of sediments, content of biogenic silica and mean annual temperature or mean temperature of May or September. These facts reflect that primary production in the lake is chiefly controlled by mean temperature during the bloom season of diatoms. Based on the transfer function established by correlation of mean temperature and density of sediment or content of biogenic silica of sediment, quantitative climatic change history of in and around Lake Biwa are discussed. Results of these studies were published as 15 refereed papers and presented as 64 oral presentations.
