  1. 1. Designens roll i visualiseringav glaciärers massbalans

    Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Författare :Tobias Thorell; [2023]
    Nyckelord :Visualisering; datavisualisering; hållbar utveckling; gr;

    Sammanfattning : Ett av de största hållbarhetsutmaningarna idag är den förändrandemassbalansens av glaciärer och dess påverkan på vårt dricksvatten. Genomgrafisk design kan vi förklara dessa komplexa problem med hjälp avvisualisering. LÄS MER

  3. 2. Anticipating Glacier Lake Outburst Floods (GLOFs): an impact-based forecasting framework for managing GLOF risks in Nepal.

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Grace Muir; [2023]
    Nyckelord :Anticipatory Action; Impact-based Forecasting; Glacier Lake Outburst Flood; Nepal; Risk-informed Early Action; Prediction; Disaster Risk Management; Science General;

    Sammanfattning : Glacier lake outburst floods (GLOFs) are an increasingly documented threat across the Himalayan region, wherein Nepal is situated. GLOFs involve a rapid discharge of water from a lake situated at the side, front, within, beneath, or on the surface of a glacier. LÄS MER

  4. 3. Analysis of Rainfall-runoff processes at different scales in two mountainous, Arctic catchments in northern Sweden

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :June Johansson; [2023]
    Nyckelord :Arctic hydrology; Catchment response parameters; Water height recession analysis; Permafrost presence; Glacier presence;

    Sammanfattning : The hydrological regime in Arctic catchments is being altered as an effect of climate change. To be able to project future changes in Arctic hydrology and hydrogeology, the mechanisms and drivers affecting runoff generation needs to be understood. LÄS MER

  5. 4. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

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

    Författare :Petter Ideström; [2023]
    Nyckelord :Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

    Sammanfattning : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. LÄS MER

  7. 5. Glacier front variatons in Sweden: 2015-2022

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Martin Houssais; [2023]
    Nyckelord :Swedish glaciers; Glacier front variation; Remote sensing; MaQiT; Sentinel-2; Handheld GNSS; UAV photogrammetry; Total station;

    Sammanfattning : This study aims at increasing the amount of data available on recent past Swedish glacier front variations, at improving the knowledge on the present behavior of these glaciers, and at contributing to the defnition of the guideline for future of glacier front observations in Sweden. To do so, the study proposes Sentinel-2 based yearly front variation measurements for 22 Swedish glaciers between 2015 and 2022, calculated based on the multicentreline approach of the MaQiT tool.
