Fluxes of CO, CH, and NO in tundra-covered and Nothofagus forest soils in the Argentinian Patagonia.

While most soils in periglacial environments present high fluxes of CO (F), CH (F), and NO (F), few of them have a tendency to drain greenhouse gases from the atmosphere. This study aimed to assess greenhouse gas fluxes at different sub-Antarctic sites and time periods (at the beginning of thaw and height of summer). To investigate the time of year effect on greenhouse gas emissions, F, F, and F were measured at two sites tundra-covered (Ti and Th) and Nothofagus forest soil (Nf) on Monte Martial, at the southernmost tip of South America, Tierra del Fuego, Argentina.
