Preliminary Identification Ground-water Nitrate Sources Nitrogen and Carbon Stable Isotopes
2009/10/20
Increasing nitrate-N in ground water is a problem in many areas with limited ground-water supplies, such as west-central Kansas. However, potential sources of nitrate-N are not known. Nitrate-N concen...
Stable isotopes in deep-sea corals and a new mechanism for “vital effects”
