Summary
Abstract: Paleoatmospheric records of trace-gas concentrations recovered from ice cores
provide important sources of information on many biogeochemical cycles
involving carbon, nitrogen, and oxygen. Here, we present a 106,000-year record
of atmospheric nitrous oxide (N2O) along with corresponding isotopic records
spanning the last 30,000 years, which together suggest minimal changes in the
ratio of marine to terrestrial N2O production. During the last glacial
termination, both marine and oceanic N2O emissions increased by 40 +/- 8%. We
speculate that our records do not support those hypotheses that invoke
enhanced export production to explain low carbon dioxide values during
glacial periods.
