Isotopic evidence that recent agriculture overprints climate variability in nitrogen deposition to the Tibetan Plateau
The stable isotopes of nitrogen in nitrate archived in polar ice have been interpreted as reflecting a shift in reactive nitrogen sources or changes in atmospheric chemical reactivity. Here, we present a novel concentration and isotopic record of nitrate (δ15N-NO3−) from a central Tibetan Plateau ic...
