  1. 6. Effects from Firn Density on Radar Derived Depth to Perennial Firn Aquifer, Lomonosovfonna, Svalbard

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Daniel Estmark; [2022]
    Nyckelord :Perennial Firn Aquifer; Glacier; Svalbard; Mass balance; GPR; Lomonosovfonna; Flerårig firn akvifär; glaciär; Svalbard; massbalans; GPR; Lomonosovfonna;

    Sammanfattning : As the climate is changing, there are clear impacts on the mass balance of glaciers. A glacier can be defined as the result of sufficient accumulation, in the form of snow and rain, compared to its ablation, the different types of glacial loss, a balance that then determines the size of the glacier.

  3. 7. Path Planning and Path Following for an Autonomous GPR Survey Robot

    Master-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Maurice Meedendorp; [2022]
    Nyckelord :robotics; gpr; autonomous; robot; ros; slam; path follow; path plan; obstacle avoidance;

    Sammanfattning : Ground Penetrating Radar (GPR) is a tool for mapping the subsurface in a non-invasive way. GPR surveys are currently carried out manually; a time-consuming, tedious and sometimes dangerous task. This report presents the high-level software components for an autonomous unmanned ground vehicle to conduct GPR surveys. LÄS MER

  4. 8. Integration of geology with geophysics : Case studies from Svalbard

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Sofia Rylander; Anna Sterley; [2022]
    Nyckelord :Gravity Measurements; Magnetic Measurements; Anomalies; Seismic; Fault Zones; Svalbard;

    Sammanfattning : This is a study where new and old geophysical data together with information found in literature has been integrated to get a better understanding of the geological evolution of Svalbard. The purpose of the study is to acquire and integrate different geophysical data over the Central Spitsbergen Basin (CSB) and across the Billefjorden Fault Zone (BFZ). LÄS MER

  5. 9. 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 nearsurface geophysics instrumentation and practices, geophysical surveys in archaeology are not commonly used in Sweden. However, it is becoming increasingly popular, especially the use of ground-penetrating radar and metal detectors. LÄS MER

  7. 10. 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 conditions in the subsurface. The use of geophysics is also a commonly used method in archaeological surveys, although traditionally not as much in Sweden. LÄS MER
