Radionuclides as tracers for particle flux and transport of water masses in the Atlantic sector of the Southern Ocean
The natural uranium decay series provide a suite of tracers to study transport processes in the ocean. We have used nuclides of the particle-reactive elements Th, Pa, Pb and Po for studies of particle flux in the Southern Ocean, whereas isotopes of the elements Ra and Ac served as tracers for the tr...
