The data for radium isotopes in coastal aquifers

The variation in radium activity within an intertidal aquifer poses significant uncertainties in estimating submarine groundwater discharge (SGD) and associated chemical fluxes. This study presents the first global findings on the seasonal variation of radium isotopes in a two-dimensional cross-section of an intertidal aquifer. This dataset includes the radium isotopes data, other groundwater data, sea level data, and numerical modeling data
