16. Våtmarksbatymetri : djupmätning av 10 anlagda våtmarker i Mälardalen
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Tio anlagda våtmarker i jordbrukslandskap i Mälardalen har undersökts i syfte att bestämma vattendjup och volym samt för att studera batymetriska metoder som kan vara lämpliga vid djupmätning av fosfordammar och andra grunda våtmarker. De metoder som använts är portabelt, kastbart ekolod som både släpats bakom kajak och kastats med fiskespö från land samt manuell mätning med mätsticka. READ MORE

19. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands
University essay from SLU/Dept. of Aquatic Sciences and AssessmentAbstract : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems. Constructing wetlands is one way to improve nutrient retention in the modern agricultural landscape. However, constructed wetlands can emit substantial amounts of methane (CH4). READ MORE

20. Nutrient Retention in Constructed Wetlands
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Eutrophication, a surplus of nutrients, is a problem in aquatic environments and one of the Swedish Environmental Goals is that there should be no eutrophication caused by human activities. Constructed wetlands (CW:s) is a measure that could be implemented to decrease the transport of nutrients to water bodies through retention. READ MORE
