Abstract: Nitrous oxide (N2O) is a strong greenhouse gas whose mole fraction in the atmosphere has increased over the industrial period. We present a new set of isotope measurements of N2O in air extracted from ice… read more here.

DOI: 10.1073/pnas.2416002121
Abstract: The proportionality of oxygen-to-nitrogen isotope effects (18ε/15ε) is used as a key isotopic signature of nitrogen cycling processes in the environment. Dissimilatory nitrate reduction is observed to have an 18ε/15ε proportionality of ~0.9 in marine… read more here.

Abstract: Among the environmental factors that have an effect on the isotopic signature of tree rings, the specific impact of soil moisture on the Δ13C and, in particular, the δ18O ratios has scarcely been investigated. We… read more here.
