1. Greenhouse gas emissions and carbon burial in a small pond
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. LÄS MER
2. Evaluation of probabilistic forecasts in Uppsala and its potential use in winter road maintenance
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Efficient winter road maintenance is crucial for safety and societal function during the winter months in Sweden. This report aims to evaluate the MetCoOp ensemble system CMEPS and investigate its potential use as a basis for formulating criteria for snow removal that accounts for forecasted weather. LÄS MER
3. EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits
Master-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonikSammanfattning : European iron production is to a large extent dependant on massive Kiruna type apatite-iron ore deposits. In this contribution, high-temperature magnetite samples from apatite-iron-oxide deposits are investigated by means of Electron Backscattered Diffraction. However, the origin of Kiruna-type deposits is still unresolved. LÄS MER
4. Internbelastningsrisk från våtmarkssediment
Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : Syftet med studien var att kvantifiera internbelastningsrisken i 21 anlagda våtmarker i jordbruksområden runt sjön Mälaren i Sverige. Även att utvärdera hur avrinnings- och våtmarksfaktorer påverkar internbelastningsrisken. LÄS MER
5. Phosphorus accumulation in constructed wetlands : A study of 10 wetlands constructed on agricultural clay soils in Södermanland
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Eutrophication is a major problem causing algal blooms and impaired water quality, especially regarding coastal areas and seas. It is a result of an excessive supply of nutrients such as phosphorus (P), where agriculture accounts for the largest share of the anthropogenic nutrient load. LÄS MER
