Nature Reviews Chemistry, 2018 39Ar is an ideal tracer for radioactive dating in the 50–1000 year range of deep ocean circulations. However, extremely low concentrations of 39Ar in the ocean make the dating process long and costly. Applied quantum technologies can, however, drastically simplify ocean dating procedures.

The Demographics of Water: A Review of Water Ages in the Critical Zone [PDF]
Reviews of Geophysics, 2019 AbstractThe time that water takes to travel through the terrestrial hydrological cycle and the critical zone is of great interest in Earth system sciences with broad implications for water quality and quantity. Most water age studies to date have focused on individual compartments (or subdisciplines) of the hydrological cycle such as the unsaturated or
