It was a significant and wise decision of the GEOSECS leaders that they focused on radionuclides and stable isotopes, which are almost free from contamination, and did not get involved in trace element geochemistry Obviously, without having the real concentration data, any arguments that might be built upon them would be meaningless Obtaining clean (uncontaminated) water samples from various depths of .
