研究実績の概要

This project has led to the publication of two papers on C0023 in Geochemistry Geophysics Geosystems (PI is first author of one of two papers). Data are available in a free online data repository.
Data were acquired on nearby sites and are going to be available online.
Numerous scientific communications in international conferences were given by PI and co-investigators.
