Welcome to my personal site
The drilling in Trüllikon-Rudolfingen (Canton Zurich) started under perfect weather conditions. The fine-grained lacustrine sediment layer is as thick as expected. Therefore, the collection of samples for noble-gas analysis was straightforward.
Unexpectedly successful: we were able to squeeze sandy sediments into our small copper tubes for the analysis of noble gases in the sediment pore water! Here a few impressions…
… and here additional evidence in a short video!
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).
