Research Abstract

Six piston core samples and two drilling samples from Lake Biwa were obtained in 2007 and 2008. Those core sediments have a potential which is clarified the precise environmental change during past 300,000 years on the basis of tephrochronologial data and 14C dating. Paleomagnetic information and paleotemperature information also were obtained. Shallow seismic survey of total 300km revealed the sediment stratigraphy in whole North Lake region of Lake Biwa.
