  1. 1. Influence of permafrost disintegration on wetland carbon fluxes in Abisko, Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Aida Esmailzadeh Davani; [2021]
    Keywords : Physical Geography; Ecosystem Analysis; Permafrost; CH4 flux; CO2 flux; Abisko; Wetlands; Earth and Environmental Sciences;

    Abstract : The northern permafrost regions are experiencing a rapid warming as surface temperatures are rising, causing a disintegration of permafrost and a deepening of the active layer (AL). This releases previously frozen carbon, making it available for decomposition by microbes. READ MORE

  2. 2. Creating a workflow of 3D building data in a municipality context

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tom Bendiksen; [2021]
    Keywords : Physical Geography and Ecosystem analysis; 3D City Models; 3D Building Models; CityGML; CityJSON; 3DCityDB; NS Building; 3D City Information Modeling; Geomatics; Earth and Environmental Sciences;

    Abstract : 3D city models are valuable tools for visualization and analytical purposes in the urban environment. A popular format for city models is CityGML, an open data model that can be used for storage and exchange of 3D city models. READ MORE

  3. 3. The potential for Binding PFAS Using Biochar and Phytoremediation

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Josefin Alice Maria Svensson; [2021]
    Keywords : Physical geography; ecosystem analysis; PFAS; Per-and polyfluoroalkyl substances; remediation; phytoremediation; biochar; Earth and Environmental Sciences;

    Abstract : PFAS is a group of long-lasting chemicals with multiple known toxicological effects which has been found everywhere in nature. One of the possible source points of PFAS is via landfill through leachate leaving the area. It is therefore important to investigate and implementing remediation techniques to reduce the contamination risk. READ MORE

  4. 4. Testing the potential to evaluate vegetation optical depth with ecosystem water dynamics in a temperate forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ainahu Abdul Hamid; [2021]
    Keywords : Physical geography; Ecosystem analysis; Vegetation optical depth; Temperate Forest; Climate; LPJ-GUESS; Evapotranspiration; Leaf water potential; Isohydricity; Hydraulic failure; Carbon starvation; Earth and Environmental Sciences;

    Abstract : Warming trends have been associated with drought which induces and heightens agents and factors that cause tree mortality. Remotely sensed observations are increasingly being used in vegetation studies and are obtained from Earth observation satellites. READ MORE

  5. 5. Monitoring wetland cover changes during the past two decades within the protected areas of the Sudd wetland in South Sudan using MODIS data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Charlotta Ruuskanen; [2021]
