  1. 1. Ash distribution and cavities in Icelandic glaciers, a marker for snow accumulation and radar signal velocity change

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Andrea Håkansson; [2020-01-15]
    Nyckelord :Iceland; GPR; CMP; Glacier; Vatnajökull; Háabunga; Langjökull;

    Sammanfattning : Glaciers in the geologically active Iceland has a high scientific as well as touristic value.In this thesis, the two largest glaciers on Iceland have been studied with GPR to find ifthe method is suitable to use in future glaciolocial studies where accumulation patternsand similar attributes are in focus in a world of deglaciation.

  2. 2. Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces

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

    Författare :Jip Jan van Zoonen; [2020]
    Nyckelord :Geography; Geographical Information Systems; GIS; Physical Geography; Digital Elevation Model; DEM; Glaciology; Earth and Environmental Sciences;

    Sammanfattning : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. LÄS MER

  3. 3. Mass Balance of the High-Arctic Glacier Nordenskiöldbreen, Svalbard, in a Changing Climate

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten och landskapslära

    Författare :Maja Gustavsson; [2019]
    Nyckelord :Mass balance; glacier; Nordenskiöldbreen; climate change; Massbalans; glaciär; Nordenskiöldbreen; klimatförändringar;

    Sammanfattning : Melting glaciers are the major contributor to sea level rise. Glaciers are sensitive indicators of climate change and current experience strong developments in a rapidly warming Arctic environment. LÄS MER

  4. 4. Assessing evolution of ice caps in Suðurland, Iceland, in years 1986 - 2014, using multispectral satellite imagery

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

    Författare :Alicja Miodonska; [2019]
    Nyckelord :remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

    Sammanfattning : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. LÄS MER

  5. 5. Sea Level Rise Vulnerability Assessment for Abu Dhabi, United Arab Emirates

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

    Författare :Marwa al Kabban; [2019]
    Nyckelord :Physical Geography and Ecosystem analysis; GIS; Sea Level Rise; Vulnerability Assessment; Modelling Sea Level Rise; Impacts Assessment of Sea Level Rise; GIS application in Sea Level Rise; Disaster Risk Reduction DRR ; Government Information Sharing GIS ; ArcGIS Web App Builder Dashboard; Sea Level Rise Story Map; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : The phenomenon of global warming has become a fact, however; the uncertainty is about the magnitude and acceleration of its manifestations. Global mean sea level rise is one of the results induced by global warming and is happening with an undetectable accelerated pace. LÄS MER
