  1. 1. Effects from Firn Density on Radar Derived Depth to Perennial Firn Aquifer, Lomonosovfonna, Svalbard

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Daniel Estmark; [2022]
    Keywords : Perennial Firn Aquifer; Glacier; Svalbard; Mass balance; GPR; Lomonosovfonna; Flerårig firn akvifär; glaciär; Svalbard; massbalans; GPR; Lomonosovfonna;

    Abstract : As the climate is changing, there are clear impacts on the mass balance of glaciers. A glacier can be defined as the result of sufficient accumulation, in the form of snow and rain, compared to its ablation, the different types of glacial loss, a balance that then determines the size of the glacier.

  3. 2. Shallow near-surface lapse rates and their connection to glacier meteorology on Storglaciären and Rabots glaciär, Northern Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Moon Taveirne; [2022]
    Keywords : Temperature lapse rate; glacier meteorology; near-­surface lapse rate; ablation gradient;

    Abstract : Glacier melt is strongly impacted by climate and meteorology. Temperature lapse rates are used to model glacier melt, and the accuracy of the spatial distribution of modelled melt can be impacted by the lapse rate used in modelling. Additionally, the observed spatial distribution of melt is highly temporally variable. READ MORE

  4. 3. Surface crevasses on Svalbard: Spatial Distribution Analysis with Focus on the Lomonosovfonna Ice Cap

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Monika Hawrylak; [2021]
    Keywords : crevasses; spatial distribution; model; glacier velocity; Lomonosovfonna; Svalbard;

    Abstract : Understanding the formation mechanics of glacial crevasses is crucial in a variety of glacial applications. Besides being a serious safety hazard during field campaigns, crevasses influence calving rates, mass balance, and the hydrological network of glaciers. READ MORE

  5. 4. Modelling the effects of climate change on ice dynamics at Kangerlussuaq Glacier, Greenland

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Jamie Barnett; [2021]
    Keywords : Glacier; Greenland; Ice Sheet; Outlet; Discharge; Sea level; Kangerlussuaq; calving; ice mélange; melt; retreat;

    Abstract : A consequence of climate change is rising global sea levels, predicted to bring increased socio-economic and environmental impacts to coastal communities. The Greenland Ice Sheet has become a prominent contributor to rising sea levels, a consequence of the Arctic warming at twice the rate of the global average. READ MORE

  6. 5. Spatial Variability in Winter Balance on Storglaciären Modelled With a Coupled Terrain Based Approach

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Yoram Terleth; [2021]
    Keywords : mass balance; accumulation; snow transport; snow drift; avalanches; glaciology;

    Abstract : Although most processes governing the surface mass balance on mountain glaciers are well understood, the causes and extent of spatial variability in accumulation remain poorly constrained. In the present study, the EBFM distributed mass balance model is newly coupled to terrain based modelling routines estimating mass redistribution by snowdrift, preferential deposition, and avalanching (ST-EBFM) in order to model winter balance on Storglaciären, Sweden.
