Abstract:

This data set includes radonuclide activities in two nearshore sediment cores collected by the piston corer from coastal South China Sea. These data could help us to constrain the anthropogenic perturbations of different terrestrial OC export to the coastal ocean.

Keyword(s):

coastal South China Sea; Pearl River Basin; Radionuclides
