  1. 1. 2D Reflection Seismic Imaging of Rødby Structures, Denmark: Geological Conditions for CO2 Sequestration

    Master-uppsats, Uppsala universitet/Geofysik

    Författare :Mussie Habtemariam Zeru; [2024]
    Nyckelord :Reflection seismic; Geologic carbon storage; Sandstone; Structures; Rødby;

    Sammanfattning : Amidst the global climate action movement, geologic carbon storage (GCS) has emerged as a pivotal strategy for mitigating atmospheric CO2 levels, offering environmental and economic opportunities. This thesis targets the Bunter Sandstone Formation within the Rødby structures in Denmark, focusing on seismic Profile 1.

  3. 2. Development and Implementation of Techniques for the Simulation and Processing for Future SAR Systems

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Tim Kinnunen; [2023]
    Nyckelord :Synthetic Aperture Radar; SAR; Reverse Backprojection Algorithm; RBPA; Backprojection Algorithm; SAR simulator; SAR processing;

    Sammanfattning : Synthetic Aperture Radar (SAR) is a type of radar system that can generate high-resolution images with which one can detect subtle changes on the scale of centimetres from space. It can operate in any weather condition and during both day and night, making it unique compared to optical sensors. LÄS MER

  4. 3. Multi-Data Approach for Subsurface Imaging: Combining Borehole and GPR- Data for Improved Analysis

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

    Författare :Pontus Yngvesson; [2023]
    Nyckelord :Geofysik; Geoteknik; GPR; Borrhål; Dataanalys; Markradar;

    Sammanfattning : The investigation to understand the subsurface and its features has long been asubject of interest for various fields, including fields such as archaeology and infras-tructure projects. However, traditional excavation methods are often costly and time-consuming. LÄS MER

  5. 4. Investigation of sub-surface ocean induction on Jupiter's icy moon Europa

    Kandidat-uppsats, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen; Uppsala universitet/Rymd- och plasmafysik

    Författare :Cornelia Ekvall; [2022]
    Nyckelord :rymdfysik; Jupiter; Europa; magnetiskdipol; JUICE;

    Sammanfattning : Following previous studies, a theoretical model for the induced magnetic field by Europa, one of Jupiter's icy moons, is presented. The aim of the model is to find evidence for the existence of a sub-surface ocean on the moon. LÄS MER

  7. 5. 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
