  1. 16. An Initial Analysis of Slurry Transportation in Subarctic Environment

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Wilhelm Friberg; [2021]
    Keywords : Slurry Transport;

    Abstract : In today’s economy, it is important to have a sustainable business model where as little as possible goes to waste or finding solutions to create something useful out of by-products. Therefore, LKAB are looking to make a large investment into creating an infrastructure of several plants to turn tailings from the production of iron ore into usable products for several industries which LKAB has designated project ReeMAP (Rear Earth Elements and MonoAmmonium Phosphate).

  3. 17. Identifying subarctic river thermal and mechanical ice break-up using seismic sensing

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Stefania Ursica; [2021]
    Keywords : Ice break-up; River ice; Subarctic; Thermal melting; Mechanical break-up; Freeze-up; Environmental seismology; Seismic signals;

    Abstract : River-ice break-up in high-latitude regions, despite its brevity, is a fundamental process, representing the most dynamic and complex period of fluvial processes. Moreover, ice break-up has significant cascading ecological effects, with a different severity for mechanical vs. READ MORE

  4. 18. Impact of fire and frost drought events on vegetation greenness and albedo in Subarctic Scandinavia

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Elin Backström; [2021]
    Keywords : Physical Geography and Ecosystem analysis; Vegetation Greenness; Albedo; Fire; Frost Drought; Earth and Environmental Sciences;

    Abstract : With climate change, the frequency in climate extremes such as drought, heavy rainfalls, and extreme temperatures is predicted to increase. These extremes can potentially stress and damage vegetation over large areas, leading to altered carbon cycle, vegetation greenness, albedo, and shifted species composition. READ MORE

  5. 19. Quantifying changes in soil bioporosity in subarctic soils after earthworm invasions

    University essay from

    Author : Joel Fransson Forsberg; [2021]
    Keywords : Biopores; macropores; geoengineering earthworms; X-ray tomography;

    Abstract : Pores provide important hotspots for chemical and biological processes in soils. Earthworm burrows affect the macropore structure and their actions may create new preferential pathways for water and gas flow within soils. This, in turn, indirectly affect plants, nutrient cycling, hydraulic conductivity, gas exchange, and soil organisms. READ MORE

  6. 20. Impact of management intensity on the plant diversity and soil carbon of grasslands in different agro-climatic regions of Sweden

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Hugo Blomberg; [2021]
    Keywords : plant species richness; pasture; meadow; soil C; subarctic; humid continental; oceanic; ploughing; fertilization; temperate; continental;

    Abstract : Biodiversity loss is a global issue and within the EU and Sweden, funding is available for practices that can enhance biodiversity. Semi-natural grasslands, either cut or grazed, have proven to host a wide range of biodiversity that can serve important eco-system functions. READ MORE
