Isotopic exchange between carbon dioxide and ozone via O(1D) in the stratosphere.
We propose a novel mechanism for isotopic exchange between CO2 and O3 via O(1D) + CO2 --> CO3* followed by CO3* --> CO2 + O(3P). A one-dimensional model calculation shows that this mechanism can account for the enrichment in 18O in the stratospheric CO2 observed by Gamo et al. [1989], using the heavy O3 profile observed by Mauersberger [1981]. The implications of this mechanism for other stra...
متن کاملIsotopic exchange of carbon-bound hydrogen over geologic timescales
The increasing popularity of compound-specific hydrogen isotope (D/H) analyses for investigating sedimentary organic matter raises numerous questions about the exchange of carbon-bound hydrogen over geologic timescales. Important questions include the rates of isotopic exchange, methods for diagnosing exchange in ancient samples, and the isotopic consequences of that exchange. This article prov...
متن کاملPartitioning net ecosystem carbon exchange and the carbon isotopic disequilibrium in a subalpine forest
We investigate the utility of an improved isotopic method to partition the net ecosystem exchange of CO2 (F) into net photosynthesis (FA) and nonfoliar respiration (FR). Measurements of F and the carbon isotopic content in air at a high-elevation coniferous forest (the Niwot Ridge AmeriFlux site) were used to partition F into FA and FR. Isotopically partitioned fluxes were then compared with an...

biometry are laborious and inefficient." In their place he describes methods, admittedly crude, which serve well for exploratory investigations. These include standardized photographs, pictorialized scatter diagrams, ideographs, hybrid indices, and "radiate indicators." Properly used, these seem not to be laborious or inefficient; more important perhaps is their appeal to many non-mathematical ...
