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

    University essay from Umeå universitet/Institutionen för fysik

    Author : Pontus Yngvesson; [2023]
    Keywords : Geofysik; Geoteknik; GPR; Borrhål; Dataanalys; Markradar;

    Abstract : 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. READ MORE

  4. 3. Sporadic-E layers in the polar cap ionosphere : A review on Es occurrence, dynamics and formation theory

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anton Thorell; [2023]
    Keywords : Sporadic-E layers; plasma physics; space physics; arctic geophysics; radar technology; UNIS; Svalbard; EISCAT.; Sporadiska E-skikt; plasmafysik; rymdfysik; arktisk geofysik; radarteknik; UNIS; Svalbard; EISCAT.;

    Abstract : Sporadic-E layers (Es) are layers of metallic ions that appear in the lower E-region of the ionosphere and can last from under one hour to several hours. Es are found at all latitudes, but polar cap Es, and specifically over Svalbard at a latitude of around 78◦ , are the focus of this study. READ MORE

  5. 4. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

    University essay from Uppsala universitet/Geofysik

    Author : Wanyi Li; [2022]
    Keywords : Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

    Abstract : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. READ MORE

  6. 5. Re-processing Reflection Seismic Data at a Quick-clay Landslide Site in Southwest Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Zhaochen Mu; [2022]
    Keywords : reprocess; reflection seismic; tomography; quick-clay; landslide;

    Abstract : This MSc thesis reprocessed seismic data collected at a site near the Gota River in 2011, focusing on two lines. The two seismic lines ran through a landslide scar zone for a total length of 1 km, both of which used dynamite as the seismic source. READ MORE
