Deep geological repositories are considered one of the safest solutions for the long-term disposal of nuclear waste. This paper presents the PRECODE experiment at BedrettoLab, Switzerland, where a new 100 m long tunnel was excavated in granite at a depth of 1300 m to investigate excavation-induced rock damage and its time-dependent evolution.

With an ongoing mass loss the Antarctic Ice Sheet contributes to global-mean sea level rise at a rate of 0.4 mm/a. Thus, it plays a key role in global climate and provides a natural laboratory to study processes that interlink cryosphere, solid Earth, atmosphere and ocean. We discuss how GNSS and seismic networks in Antarctica were used to significantly advance our understanding of these processes, and how they should be maintained and extended to answer key science questions in the future.
