Fossil fuel burning in Taylor Valley, southern Victoria Land, Antarctica: Estimating the role of scientific activities on carbon and nitrogen reservoirs and fluxes

Particulate organic and elemental carbon and nitrogen as well as NO(x) fluxes from scientific activities have been computed for Taylor Valley, Antarctica (≃78°S). These authropogenic fluxes have been compared to both the \u27natural\u27 fluxes and landscape reservoirs as determined from Long-Term Ecological Research (LTER) investigations in the valley. The anthropogenic, nongaseous carbon fluxes are minor compared to the natural fluxes, while the anthropogenic NO(x) flux may be potentially important over decadal time scales
