| Zusammenfassung |
| To date, little is known about the impact of processes which cause lateral
carbon fluxes over continents, and from continents to oceans on the CO2
– and carbon budgets at local, regional and continental scales. Lateral
carbon fluxes contribute to regional carbon budgets as follows: Ecosystem
CO2 sink=Ecosystem carbon accumulation+Lateral carbon fluxes. We
estimated the contribution of wood and food product trade, of emission and
oxidation of reduced carbon species, and of river erosion and transport as
lateral carbon fluxes to the carbon balance of Europe (EU-25). The analysis
is completed by new estimates of the carbon fluxes of coastal seas. We
estimated that lateral transport (all processes combined) is a flux of 165 Tg C yr−1 at the scale of EU-25. The magnitude of lateral transport is thus comparable to current estimates of carbon accumulation in European
forests. The main process contributing to the total lateral flux out of
Europe is the flux of reduced carbon compounds, corresponding to the sum of
non-CO2 gaseous species (CH4, CO, hydrocarbons, ...) emitted
by ecosystems and exported out of the European boundary layer by the large
scale atmospheric circulation. |
