  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. Automatic velocity estimation in GPR data and migration

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Christofer Jonason; [2020]
    Nyckelord :;

    Sammanfattning : Ground Penetrating Radar is a widely used technique for detecting objects in the subsurface. However, the objects typically appear as hyperbolic curves in the raw data's time domain. Therefore, the size and the location of the objects are hard to interpret from the raw data. LÄS MER

  5. 5. Interpolation and visualization of sparse GPR data

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Rickard Sjödin; [2020]
    Nyckelord :GPR; Ground Penetrating Radar; Interpolation;

    Sammanfattning : Ground Penetrating Radar is a tool for mapping the subsurface in a noninvasive way. The radar instrument transmits electromagnetic waves and records the resulting scattered field. Unfortunately, the data from a survey can be hard to interpret, and this holds extra true for non-experts in the field. The data are also usually in 2. LÄS MER
