We are very excited to announce that ournew paper on the detection of deep groundwater circulation with environmental DNA (eDNA), noble gases and trace elements in one of the world’s most iconic mountains – Mt. Fuji in Japan – will be published in the launch edition of the new Nature research journal Nature Water:

Schilling, O. S., Nagaosa, K., Schilling, T. U., Brennwald, M. S., Sohrin, R., Tomonaga, Y., Kipfer, R., Brunner, P., & Kato, K. (2023). Revisiting Mt. Fuji’s groundwater origins with helium, vanadium and eDNA tracers. Nat. Water, 1. https://doi.org/10.1038/s44221-022-00001-4

The groundbreaking study will be accompanied by a Springer Nature news & views highlight article feature. Moreover, on February 2^nd, Oliver Schilling will present the study online at the international Nature Water launch webinar. https://doi.org/10.52843/cassyni.gxqlk9

We are happy to welcome two new MSc students in our team:
Daniel Namendorf will investigate in his MSc thesis the impact of river restoration measures on microbial transport at the surface water-groundwater interface and develop a methodology to conduct continuous online flow cytometry directly in the field even under high sediment loading/turbidity.
Merhawi Solomon will investigate in his MSc thesis the sources of pumped groundwater at an urban riverbank filtration site with different environmental tracer techniques, and quantify the impact of ongoing river restoration measures on surface water-groundwater mixing dynamics.

Yama Tomonaga and Oliver Schilling presented research and participated in the Pallas Symposium at the Pallas atmosphere-ecosystem supersite on the northern edge of the Boreal forests in northern Finland. After the symposium, we conducted a two day field sampling campaign in Pallas with our good friend Pertti Ala-Aho of Oulu University and analysed dissolved gases directly on site with one of our miniRUEDIs, accompanied by some water and eDNA sampling for microbial analyses.
