Measuring Greenhouse Gas Emissions from a Canadian Reservoir

摘要

Monitoring of natural aquatic ecosystems and the newly flooded Eastmain-1 reservoir demonstrates the following:rn1. CO_2 and CH_4 gross fluxes increase rapidly within the first year after flooding;rn2. Eastmain-1 reservoir gross CH_4 fluxes returned to values similar to natural aquatic ecosystems the second year after flooding;rn3. Eastmain-1 reservoir CO_2 gross fluxes returned to values similar to natural aquatic ecosystems the third year after flooding; which is well within the ten years generally observed for boreal reservoirs; andrn4. Automated systems and floating chambers techniques give similar results on annual mass balance.
