资源简介：
Supra-permafrost submarine groundwater discharge (SGD) in the Arctic is poorly understood, yet has the potential to increase over the coming decades due to climate change. This study uses radium (Ra) isotopes to investigate this process by constraining seasonal SGD inputs to an Arctic coastal lagoon (Simpson Lagoon, AK). Within this dataset are 224Ra, 223Ra, 228Ra, and 226Ra activities for surface water samples (lagoon, rivers) and groundwater samples across three seasons: thaw (June 2022), open water (August 2021 and July 2022), and freeze up (September/October 2022). Experimentally determined valued for Ra desorption from riverine suspended sediments and diffusive fluxes from bottom sediments are also included.
