ABSTRACT:

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

ABSTRACT:

This is the data in the manuscript "Submarine groundwater discharge strengthens acidification in the coastal semi-closed bays". It includes rainfall, river discharge, evapotranspiration, atmospheric CO2 concentration, marine water quality and tidal fluctuation data. In addition, the data collected by the author is also attached.
