The drilling operations at Gebestorf-Brüel (AG) are almost finished. Here a few impressions of the last few cores (consolidated material, thus not targeted by my sampling for noble-gas analysis).
The JpGU Meeting 2018 is almost finished and this is more like a post-mortem update. Here our contributions:
- Horstmann, E., Tomonaga, Y., Brennwald, M. S., & Kipfer, R. (2018). Noble gases to study sediment transport processes around deep-sea vents. Japan Geoscience Union Meeting. Chiba, Japan.
- Tomonaga, Y., Giroud, N., Diomidis, N., Brennwald, M. S., Horstmann, E., Kipfer, R., & Wersin, P. (2018). Evolution of the gas composition in the FE experiment, an unsaturated SF/HLW emplacement drift at Mt. Terri, Switzerland. Japan Geoscience Union Meeting. Chiba, Japan.
Tomorrow we will be at the Atmosphere and Ocean Research Institute (AORI) of The University of Tokyo.
At present we are installing an on-line gas monitoring system at an hydrothermal well in the city of Beppu (Oita Prefecture, Japan), along the Japan Median Tectonic Line. This project is performed within the frame of a scientific collaboration between the Institute of Geological Sciences of the University of Bern, the Swiss Federal Institute of Aquatic Science and Technology (Eawag) (Dr. Kipfer), the Atmosphere and Ocean Research Institute (AORI) of The University of Tokyo (Dr. Sano), and the Institute for Geothermal Sciences of Kyoto University (Dr. Shibata).
The monitoring aims to provide a comprehensive dataset to infer any possible relation between gas geochemistry and seismic activity in the surrounding region. The measurements will last until the end of May 2018.
