11. Spatial variation in GHG emissions from drained organic forest soils : implications for Swedish UNFCCC reporting
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Drainage of organic soils for forestry generally increases soil CO2 and N2O emissions but decreases CH4 emissions. Under the United Nations Framework Convention on Climate Change (UNFCCC) countries provide annual national inventories of anthropogenic greenhouse gas (GHG) emissions and removals, which includes emissions of GHGs from drained organic forest soil.

12. Greenhouse gas emissions from compacted peat soil
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Cultivated peat soils are a main driver for CO2 and N2O emissions, while the gas fluxes are dependent on intrinsic soil properties and land use. Sand addition into peat soils might reduce greenhouse gas (GHG) emissions and enhance soil strength, and thus the ability to tolerate soil compaction. READ MORE

13. ICOS Atmospheric Stations: Spatial Characterization of CO2 Footprint Areas and Evaluating the Uncertainties of Modelled CO2 Concentrations
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The main purpose of this thesis is to present and analyze spatial characteristics of 31 different European atmospheric measurement stations in the ICOS (Integrated Carbon Observation System) station network. The characterization includes quantification of where air arriving at the stations can be expected to have come from, as well as a breakdown of what these areas cover with regards to land cover, point source emissions and population.

14. Methane flux in the Doñana wetlands : Waterbird guano addition and benthicinvertebrate effects
University essay fromAbstract : Wetlands are globally important biogeochemical hotspots, and their roles as either significant sources of greenhouse gas or carbon sinks are strongly controlled by environmental drivers such as carbon, nitrogen, and phosphorus availability, which can stimulate emission of three greenhouse gases: nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4). Mounting evidence suggests that aquatic invertebrate activity can enhance wetland greenhouse gas flux, through bioturbation and bioirrigation of surrounding sediments. READ MORE

15. Summer CO2 fluxes : A field study from three large lakes in Sweden
University essay from Linköpings universitet/Tema MiljöförändringAbstract : Increasing levels of CO2 in the atmosphere is a contributing cause to climate change. To give a better understanding, natural sources of CO2 is as important as anthropogenic sources, such as burning fossil fuels. READ MORE
