Outline of Annual Research Achievements

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.
