1. Kolbestånd i restaurerade våtmarker, En fältstudie av anlagda våtmarker i Lunds kommun
Master-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : Sedimentation of organic carbon in shallow lakes and wetlands removes CO2 from the atmosphere and can be considered a natural carbon sink. Actions toward regulating restored wetlands as carbon sink would provide Lund municipality with solution to combat CO2 emission goals for the future. LÄS MER
2. Variability of summer CH4 and CO2 flux rates in and between three large Swedish lakes : A spatio-temporal field study
Kandidat-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Understanding of natural greenhouse gas (GHG) cycles is crucial for making GHG budgets, which work as basis in climate change and global warming policy programs. Lakes as a source for GHG activity have only recently been included in global GHG budgets, and most studies of lake GHG flux rates are conducted on lakes <10 km2, which only comprise roughly half of the global lake area—making data of large lake flux rates scarce.

3. Greenhouse gas flux at a temperate peatland : a comparison of the eddy covariance method and the flux-gradient method
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Northern peatlands have accumulated carbon for thousands of years and currently hold around one third of all soil carbon on earth. Large uncertainties are associated with predictions of how northern peatlands will react to climate change. LÄS MER
4. Modellering av oorganiskt kol i boreal jord och vattendrag med hjälp av PHREEQC : Modelling of dissolved inorganic carbon in boreal soils and streams using PHREEQC
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Syftet med examensarbetet har varit att studera kol i mindre vattendrag med hjälp av jämviktsmodellering i PHREEQC. Fokus har varit dynamik av löst icke organiskt kol (DIC) samt att förstå hur mycket koldioxid (CO2) som avges från mindre vattendrag och om den mängden har signifikant inverkan på den globala kolbalansen.

5. The dynamics of non-methane hydrocarbons and other trace gas fluxes at a subarctic mire in northern Sweden
Magister-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : In the context of climate change, it is important to understand how the terrestrial carbon cycle is interacting with the anthropogenic increase in atmospheric carbon dioxide (CO2) concentration. Boreal and subarctic regions in the northern hemisphere are great carbon pools, as well as they are subject to predicted warming. LÄS MER
