  1. 1. Seasonal Velocities on Nordenskiöldbreen, Svalbard

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lena Elisa Ehwald; [2016]
    Nyckelord :Nordenskiöldbreen; Svalbard; velocity; glaciers; climate change; mass balance; dynamical behaviour of glaciers; Glaciär; Svalbard; Nordenski öldbreen; isflöde; massbalans; klimatuppvärmnin;

    Sammanfattning : Global warming leads to increased precipitation in the Arctic, as warmer air can carry more moisture. The consequence is that many arctic glaciers get steeper slopes over time as increased melt at their lower part causes thinning and increased solid precipitation in their upper regions leads to thickening of the glacier.

  3. 2. Short-Term Surface Velocity Changes During Summer in the Lower Part of the Ablation Area Using Differential GPS Survey, Storglaciären, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :David Grenot; [2016]
    Nyckelord :DGPS; short-term ice velocity; infinitesimal strain; Storglaciären; ablation area; DGPS; korttidsvariationer i isflöde; deformation; Storglaciären; ablationsområde;

    Sammanfattning : short time scale. Four differential GPS stations were installed in the lower ablation area of Storglaciären in Sweden for one week in August 2012. The position data over the period were then compared with the environment information including temperature, precipitation, known hydrology and topography. LÄS MER

  4. 3. Short-term variations in ice dynamics during the spring and summer period on Storglaciären, Kebnekaise, Sweden.

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

    Författare :Helena Psaros; [2012]
    Nyckelord :Storglaciären; DGPS; short-term variation; spring event; temperature; hydrological system; ice motion;

    Sammanfattning : Two Differential GPS (DGPS) stations were set up on Storglaciären in the upper and lower part of the ablation area to study short term variations of Storglaciären’s motion. The study period lasted from April to July 2009 and the DGPS logged data every second. LÄS MER
