Deskripsi
In this study, a new analytical technique is employed to measure Kr and Xe isotopes in groundwater at high precision. These measurements indicate that gravitational signals of past water-table depth are preserved in ancient groundwater, representing a novel proxy for past terrestrial hydroclimate.
