  1. 1. Ice Sheet Modeling: Accuracy of First-Order Stokes Model with Basal Sliding

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Eskil Jonsson; [2018]
    Nyckelord :Ice sheet modelling; First-Order Stokes model; basal sliding; Stokes equations;

    Sammanfattning : Some climate models are still lacking features such as dynamical modelling of ice sheets due to their computational cost which results in poor accuracy and estimates of e.g. sea level rise. LÄS MER

  3. 2. Paleoglaciological study of the Ahlmannryggen, Borgmassivet and Kirwanveggen nunatak ranges, Dronning Maud Land, East Antarctica, using WorldView imagery

    Master-uppsats,

    Författare :Taisiya Dymova; [2018]
    Nyckelord :;

    Sammanfattning : Paleoglaciological reconstructions based on glacial geological and geomorphological traces are used to test and constrain numerical models of ice sheet extent and dynamics. MAGIC-DML (“Mapping, Measuring and Modelling Antarctic Geomorphology and Ice Change in Dronning Maud Land”) project is trying to reconstruct the timing and pattern of ice surface elevation changes since the mid-Pliocene across western Dronning Maud Land, East Antarctica.

  5. 4. Three-dimensional modeling of Quaternary sediments and valley morphology, Bollnäs, Sweden.

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Veronica Nord; [2014]
    Nyckelord :;

    Sammanfattning : This study demonstrates how to make and use a three dimensional model in GSI3D, based on well data from the Geological Survey of Sweden’s well archive. The objective is to determine if it is possible to show a supposed fault scarp, the Bollnäs fault, in the bedrock and the valley morphology in a 3D model based on the data available. LÄS MER

  7. 5. Modeling albedo in the dry snow zone of the Greenland ice sheet

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Johanna Eggeling; [2014]
    Nyckelord :Earth and Environmental Sciences; Physics and Astronomy;

    Sammanfattning : Hirham5, a weather model developed at DMI, does not have a very good approximation for the snow albedo. To make the model better a snow albedo code, based on Dickenssen’s equation for snow albedo, was implemented in the model where the albedo depended on more variables than just the temperature. LÄS MER
