Description:
The current accounting of forests as carbon sinks has relied on measurements of vertical carbon dioxide (CO2) exchange between vegetation and the atmosphere. The budgets have ignored dissolved carbon (C) and nitrogen (N) transport in water to streams and lakes and the subsequent exchange between the atmosphere and surface waters. Aquatic habitats can be significant net sources of CO2 and methane (CH4) and potential hot spots for N2O release, all important for natural greenhouse gas (GHG) emissions. Inland waters need to be included in the C and GHG balances for terrestrial landscapes. This project aims to quantify GHG balances at the landscape scale in forested regions that include land-atmosphere, land-water, and water-atmosphere exchange of CO2, CH4 and N2O. New measurements and technologies as well as available data from ongoing environmental monitoring will be used to estimate the overall landscape net C and GHG balances at different scales by linking data with models. The project will establish an ICOS site for long-term monitoring of whole watershed GHG exchange that is representative for the southern boreal zone. This projects combines expertise regarding terrestrial, aquatic, and atmospheric processes, and biogeochemical cycling and modeling, at six Swedish universities, take advantage of major national and international research infrastructure networks, and will provide recommendations of landscape management to minimize GHG release.
