1. 1. 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

3. 2. Meteorological Conditions on Nordenskiöldbreen Glacier, Svalbard (2009 – 2015)

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Niclas Bergman; [2017]
   Keywords : Svalbard; Nordenskiöldbreen; glacier; albedo; Svalbard; Nordenskiöldbreen; glaciär; albedo;

   Abstract : Glacial environments in the Arctic are a much-studied topic as well as a field of research with strong influences regarding the current and future global climate of our planet. This report is focused on the meteorological conditions on Nordenskiöldbreen glacier from 2009-2015 and how they correlate with each other, the glacier surface and the surrounding terrain. READ MORE

4. 3. Differential Interferometry and Multiple-Aperture Interferometry for Retrieving Three-Dimensional Measurements of Glacial Surface Velocity

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Luke Webber; [2016]
   Keywords : Differential Interferometry; Multiple-Aperture Interferometry; 3D; Glacial Surface Velocity;

   Abstract : The measurement and monitoring of glacial surface velocity is important for many aspects of glaciology, such as determining the mass balance, for characterising the stability or instability of glaciers, or the identification of potential hazards from surging glaciers or Jökulhlaups, a type of glacial outburst flood. Predominately measurements of glacial surface velocity have been produced using either differential interferometry (DInSAR) applied to radar data, or offset-tracking applied to either optical or radar data.

5. 4. Applying GIS to Investigate the Spatial Variability of Sub-Glacial Hydrology under Land Terminating Ice Sheets in Western Greenland Ice Sheet.

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Welsh Samuel; [2016]
   Keywords : Hydraulic potential; Greenland; GIS; sub-glacial hydrological network; ice sheet dynamics; Hydraulisk potential; Grönländ; GIS; sub-glacial hydrologi; istäckesdynamik;

   Abstract : With continued warming regional surface air temperatures around the Artic in recent decades, there is growing importance in understanding how ice sheet dynamics interact with a shifting global climate system. This research investigates the spatial variability of sub-glacial hydrology under land terminating ice sheets in Western GrIS, when applying varying overburden ice pressures within Shreve’s (1972) hydraulic potential equation.
