Signature of Arctic surface ozone depletion events in the isotope anomaly (Δ17O) of atmospheric nitrate
Arctic surface ozone isotope anomaly atmospheric nitrate
2008/12/3
We report the first measurements of the oxygen isotope anomaly of atmospheric inorganic nitrate from the Arctic. Nitrate samples and complementary data were collected at Alert, Nunavut, Canada (82°30 ...
Long-term observation of mass-independent oxygen isotope anomaly in stratospheric CO2
mass-independent oxygen isotope anomaly stratospheric CO2
2008/11/24
Stratospheric and upper tropospheric air samples were collected during 1994–2004 over Sanriku, Japan and in 1997 over Kiruna, Sweden. Using these archived air samples, we determined the triple oxygen-...
Carbon isotope anomaly in the major plant C1 pool and its global biogeochemical implications
Carbon isotope major plant C1 pool global biogeochemical implications

We report that the most abundant C1 units of terrestrial plants, the methoxyl groups of pectin and lignin, have a unique carbon isotope signature exceptionally depleted in 13C. Plant-derived C1 volati...
