  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.

  2. 2. Reconstruction of Radio Detector Data using Graph Neural Networks

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Arnau Serra Garet; [2023]
    Nyckelord :;

    Sammanfattning : The current neutrino detectors have been able to detect neutrinos in the range of TeV to 100 PeV, however, ultra high energy (UHE) neutrinos above 100 PeV still remain to be detected. A new neutrino detector, the RNO-G, is currently being constructed in Greenland with the purpose of detecting the first UHE neutrinos using radio antennas capable of measuring the Askaryan pulse generated after a neutrino interaction with the ice molecules.

  3. 3. Can ancient pathogens emerging from glaciers and permafrost reach Europe by aerosolization?

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Anna Bruhn; [2023]
    Nyckelord :Ancient pathogens; Greenland; Aerosolized pathogens; Aerosol transport; Earth and Environmental Sciences;

    Sammanfattning : Glaciers and permafrost capture bacteria and viruses when they form, which can be suspended for millennia. This includes long since extinct pathogens which are functionally novel. As polar regions get warmer these pathogens will emerge and spread through the local ecosystem, potentially altering it.

  5. 5. Performance Optimization of Ice Sheet Simulation Models : Examining ways to speed up simulations, enabling for upscaling with more data

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Fredrika Brink; [2023]
    Nyckelord :performance optimization; Python libraries; ice sheet simulations; Numba; Joblib; upscaling; parallelization;

    Sammanfattning : This study aims to examine how simulation models can be performance optimized in Python. Optimized in the sense of executing faster and enabling upscaling with more data. To meet this aim, two models simulating the Greenland ice sheet are studied. The simulation of ice sheets is an important part of glaciology and climate change research. LÄS MER
