  1. 1. THE MONASTERY HILL: GEOPHYSICAL METHODS FOR DESCRIBING ARCHAEOLOGY AND NEAR-SURFACE GEOLOGY IN LÖDÖSE, SW SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Tobias Möhl; Fredrik Andersson; [2021-09-21]
    Nyckelord :Near-surface geophysics; Ground-penetrating radar; Resistivity; Magnetic gradiometry; 3D modeling; Archaeology; Leached clay; Medieval monastery; Sweden;

    Sammanfattning : Even though Sweden has been one of the leading countries in the development of nearsurfacegeophysics instrumentation and practices, geophysical surveys in archaeology are notcommonly used in Sweden. However, it is becoming increasingly popular, especially the useof ground-penetrating radar and metal detectors. LÄS MER

  2. 2. LÖDÖSEHUS: GEOPHYSICAL METHODS FOR DESCRIBING ARCHAEOLOGY AND NEAR-SURFACE GEOLOGY AT THE SITE OF A MEDIEVAL CASTLE IN LÖDÖSE, SW SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Fredrik Andersson; Tobias Möhl; [2021-09-21]
    Nyckelord :Near-surface geophysics; Ground-penetrating radar; Resistivity; Induced Polarization; Archaeology; Leached clay; Medieval castle; Lödösehus; Lödöse; Sweden;

    Sammanfattning : Near-surface geophysics is a well established method for mapping the geological conditionsin the subsurface. The use of geophysics is also a commonly used method in archaeologicalsurveys, although traditionally not as much in Sweden. LÄS MER

  3. 3. Evaluation of the applicability of geophysical methods when characterizing mine waste in Yxsjöberg, Sweden

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Palo Matilda; [2021]
    Nyckelord :geophysics; Yxsjöberg; mine tailings;

    Sammanfattning : Smaltjärnen tailings repository located in Yxsjöberg, Sweden, attracts researchers with questions regarding characterization and potential re-mining. This thesis continuous geophysical characterization done by researchers from the Exploration Geophysics department at Luleå University of Technology but using new data from 2019. LÄS MER

  4. 4. Electric Transport of Rare-earth Metal Oxy-hydride Thin Films

    L3-uppsats, Uppsala universitet/MaterialfysikUppsala universitet/Tillämpad kärnfysik

    Författare :Suraya Kazi; [2021]
    Nyckelord :Photochromism; Photoconductivity; Rare-earth Metal Oxy-hydride; Electric Transport; Photodarkening; Yttrium Oxy-hydride;

    Sammanfattning : In this project, I investigate the photoconductivenature of photochromic rare-earth metal oxy hydrides (REMHO). Such materials have received increasingscientific attention since they show a color-neutralphotochromic effect that can be applied, e.g., in smartwindows or chromogenic devices. LÄS MER

  5. 5. Integration of Borehole, Ground, andAirborne Data to Improve Identificationof Areas With Quick Clays in Sweden

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Oskar Rydman; [2021]
    Nyckelord :TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Landslides; Frastad; TEM; tTEM; Quick clay; SkyTEM; ATEM; CPTR; CPTU-R; Jordskred; Fråstad;

    Sammanfattning : The main focus of the project was the comparison of results from a new towed transientelectromagnetic (tTEM) data set with existing data including airborne transient EM(ATEM), radio magnetotellurics (RMT), cone penetration test with resistivity (CPT-R),geotechnical interpretations and geological observations in a quick clay landslide site atFråstad close to Lilla Edet in south-west Sweden. The tTEM data set was processedand inverted twice in the software Aarhus workbench using different inversion constraintsand settings. LÄS MER
