This data table includes in-situ near-shore seawater measurements of excess radon (Rn-222) and water levels collected in Faga'alu Bay, Tutuila, American Samoa.
Radon (Rn-222) data were collected to characterize the advection rate of groundwater onto the near-shore reef. When analyzed in conjunction with measurements of changing water levels from tides and waves, the data can be used to assess the potential for terrestrial groundwater intrusion on the reef and the sources and fate of these water masses.
