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

    University essay from Uppsala universitet/Geofysik

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

    Abstract : 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. Comparison of Magnetic-Susceptibility Models From UAV-borne and Ground Measurements in Enåsen Area, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Clara Sjödin; [2022]
    Keywords : magnetic susceptibility; Enåsen area; UAV survey; magnetic anomalies; Potent; magnetisk susceptibilitet; Enåsen; drönare; magnetiska anomalier; Potent;

    Abstract : Mapping anomalies in the Earth’s magnetic field is one method used in applied geophysics, for exploring buried structures and objects. Magnetic surveys can be ground-based or made airborne, onboard airplanes, helicopters, or unmanned aerial vehicles (UAV), also known as drones. READ MORE

  4. 3. First-arrival traveltime tomography of active-source data in the Kansanshi copper mine, northern Zambia

    University essay from Uppsala universitet/Geofysik

    Author : Vessela Hobson; [2019]
    Keywords : refraction seismics; tomographic inversion; Zambian Copperbelt; copper;

    Abstract : Sedimentary rock-hosted deposits are a major source of copper and cobalt, with the Neoproterozoic central African Copperbelt being among the largest Cu-Co provinces in the world, accounting for around 15% of its copper resource. The deposits occur primarily in the carbonates and siliciclastic sediments overlying the basement, and formed during early diagenesis (around 820 Ma) and late diagenesis/metamorphism during the Pan-African Orogeny (580-520 Ma).

  5. 4. Processing of Noisy Controlled Source Audio Magnetotelluric (CSAMT) Data

    University essay from Uppsala universitet/Geofysik

    Author : Julia Fridlund; [2019]
    Keywords : CSAMT; noise; magnetotelluric transfer functions; robust processing; transients; bias; CSAMT; brus; magnetotelluriska överföringsfunktioner; robust processering; transienter; bias;

    Abstract : Controlled Source Audio Magnetotellurics (CSAMT) is a geophysical method for characterizing the resistivity of the subsurface with the help of electromagnetic waves. The method is used for various purposes, such as geothermal- and hydrocarbon exploration, mineral prospecting and for investigation of groundwater resources. READ MORE

  6. 5. Analysis of Multicomponent Data to Study Esker Structures, Turku-Finland

    University essay from Uppsala universitet/Geofysik

    Author : Julia Fridlund; [2017]
    Keywords : Finland; esker structures; reflection seismology; multicomponent data; S-wave; Finland; rullstensås; reflexionsseismik; flerkomponentdata; S-vågor;

    Abstract : Eskers are long winding ridges that originate from gravel that has travelled in meltwater streams in glaciers. At the study site, Virttaankangas plane in southwest Finland, there are esker structures covered by sediments. One reason why it is important to study eskers is because they are used for purifying drinking water. READ MORE
