Summary
In this project, we will collect air samples inside the forest canopy at different heights to determine the 14C signature of the respired CO2 from the ecosystem in the footprint of the ICOS tower. To determine the source of the 14CO2, we will collect additional samples from vegetation and soils for 14C determination. The overall goal of the project is to obtain an estimate of the mean transit time of carbon; i.e. the time it takes carbon atoms to pass throught the ecosystem, from photosynthesis until respiration.
