    Keywords : PRISMA Hyperspectral data; lithium mineral deposits; lithium brine-rich deposits; Dashti-e- Nawar; boron deposits; Principal Component Analysis PCA ; supervised and unsupervised classification; spectral matching; spectral profile analysis; visible-near-infrared VNIR ; short-wave infrared SWIR Gypsum; Hectorite; Kaolinite; Lepidolite; lithium carbonate; lithium chloride;

    Abstract : The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with substantial potential for lithium resources beneath its land crust. READ MORE

  3. 2. Historical mining of Fe-Ca ore in Garpenberg, Sweden. : A study based on lake sediment geochemistry from Finnhytte-dammsjön.

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

    Author : Morgan Eliasson; [2023]
    Keywords : Paleolimnology; Lake sediment; XRF; Garpenberg; Mining history;

    Abstract : It is well established that mining and metallurgy on a larger scale in Sweden originated in Bergslagen. The historical mining district Garpenberg in Bergslagen presently show the oldest signs of mining in Sweden (2300 BP) based on a study of a lake sediment profile from Gruvsjön. READ MORE

  4. 3. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Wiebke Coenen; [2022]
    Keywords : Vombsj¨on; Lake profile; Cyanobacteria; Drinking water; Random Forest; Technology and Engineering;

    Abstract : Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. READ MORE

  5. 4. Future management of Laisriver Brown trout : what life history and enhancement strategy should be prioritized?

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Isak Landström; [2021]
    Keywords : salmo trutta; acoustic telemetry; spawning migration; hatchery-reared; genetic assignment; sea-run; resident; laisälven;

    Abstract : The life history and coexistence of subpopulations of brown trout in the same drainage area are relatively well known. The three forms of trout; sea-run, lake-run and resident, can all be present in the same location at some period of their life cycle, e.g. during the parr stage or at spawning. READ MORE

  6. 5. Hydrodynamic modelling of fate and transport of natural organic matter and per- and polyfluoroalkyl substances in Lake Ekoln

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Frida Ekman; [2021]
    Keywords : Ekoln; Natural organic matter NOM ; Total organic matter TOC ; Colour; degradation; sedimentation; photooxidation; PFAS; MIKE 3 FM; Ekoln; naturligt organiskt material NOM ; totalt organiskt kol TOC ; färg; nedbrytning; sedimentation; foto-oxidation; PFAS; MIKE 3 FM;

    Abstract : Societies are facing great challenges with obtaining a good quality and quantity of drinking water in the context of climate change. Increases in natural organic matter (NOM) and per- and polyfluoroalkyl substances (PFAS) have been observed in lakes and drinking water the past years, which is of great concern for water treatment plants in Sweden.
