Research Abstract |
To develop reliable environmental proxies, I clarified the interindividual differences in stable carbon and oxygen isotopes of benthic foraminifera by using microscale stable isotopic analytical system. We will be able to apply this finding to precise reconstruction of ancient water chemistry. In addition, to develop new environmental proxies, I started several collaborated studies of biogenic carbonate. For those studies, I have developed a new high precision isotopic analytical system for carbonate, DIC, and water samples.
