Limnology And Oceanography (0024-3590) (Wiley), 2022-04, Vol. 67, N. 4, P. 753-767

When rivers mix into the ocean, radium isotopes are released into the dissolved phase allowing us to apply these isotopes as powerful tracers of river plumes spreading into the ocean. We report 223Ra and 224Ra radium activities that were determined i
