An unusual marriage of miniRUEDI data, environmental DNA and vanadium tracers shows that Mt. Fuji isn’t as easy as previously thought

Mount Fuji’s freshwater springs are not only fed by water recharged at high altitude, but also by the upwelling of deep groundwater. This was observed by Oliver Schilling and his team, who used miniRUEDI data combined with environmental DNA and vanadium tracers. Read the full story in Nature Water.
