  1. 1. 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

  3. 2. Reprocessing weather data from Smart Stake weather stations on the Greenland ice sheet

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

    Författare :Leon Lovén; [2023]
    Nyckelord :ice sheet; data processing; weather station; Greenland; GEUS; Smart Stake; istäcke; databehandling; väderstation; Grönland; GEUS;

    Sammanfattning : To identify a climate trend, a lot of data is required for the conclusion to be accurate. A trend can require 30 years worth of measurements in order to say anything with certainty about how the climate is changing. It is therefore important to utilize every source of data in climate research. LÄS MER

  4. 3. Reconstructing Mid-Late Holocene Arctic Climate Using Loess Deposits From Kangerlussuaq, Greenland

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :William Mörtsjö Zung; [2023]
    Nyckelord :;

    Sammanfattning : The current geological epoch, the Holocene, began 11,700 years ago. During this time, a thermal maximum in temperature was reached somewhere during the early-middle stage at 8-5 kyrs ago which was followed by a period of neoglacial cooling, culminating in the little ice age (LIA).

  5. 4. The implication of a changing West Antarctic Ice Sheet on future sea levels and policymaking in Sweden

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

    Författare :Jonatan Åsén; My Pilfalk; [2023]
    Nyckelord :Protection; Policymaking; Sweden; WAIS; Kustskydd; Policy; Sverige; WAIS;

    Sammanfattning : This paper examines the future possible consequences of rising sea levels primarily due to melting Antarctic ice sheets. An objective is to research suitable methods for handling rising sea levels in Sweden. LÄS MER

  7. 5. The Magnetic Properties and Fabrics of Upper Pleistocene Loess on La Motte, Jersey, and their Palaeoclimate Implications

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Anya Hawkins; [2022]
    Nyckelord :last glacial; magnetic susceptibility; AMS; temperature dependent magnetic susceptibility; palaeowind reconstruction;

    Sammanfattning : The island of Jersey is an interesting location for palaeoclimate reconstruction given the likely impact of variations in North Atlantic climate and European ice sheet extent during the last glacial period considering their proximal location. These last glacial climatic variations are recorded in the loess sequence from La Motte, Jersey and in order to reconstruct these changes, a detailed magnetic analysis was performed. LÄS MER
