1. 21. Seasonal Velocities on Nordenskiöldbreen, Svalbard

   University essay from Uppsala universitet/Institutionen för geovetenskaper

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

   Abstract : 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. 22. Analysis of the Temporal Variability of Positive Degree Day Factors

   University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Author : Hanna Rönnberg; [2016]
   Keywords : Positive Degree Day Surface Mass Balance; Physics and Astronomy;

   Abstract : The surface mass balance determines the growth or decay of an ice sheet, by taking the difference between accumulation and ablation. In this thesis snow and ice ablation is related to 2m-temperature through the positive degree day method. READ MORE

4. 23. Changes in Surface Mass Balance on the Devon Ice Cap in the Canadian Arctic

   University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

   Author : Linnéa Midefelt; [2016]
   Keywords : Surface mass balance; Devon Ice Cap; Canadian Arctic; Physics and Astronomy;

   Abstract : Climate change is an ongoing process that contributes to changes in the climate on a global scale down to a local scale. The Arctic sea ice and the glaciers have continued to decrease at the same time as the rate of sea level rise has increased. READ MORE

5. 24. Snow and sea ice temperature profiles from satellite data and ice mass balance buoys

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Isabella Grönfeldt; [2016]
   Keywords : IMB; ice mass balance buoys; snow-ice interface; air-snow interface; temperature profile; snow; sea ice; Fram Strait; Greenland; Arctic Ocean; climate change; climate; physical geography and ecosystem analysis; remote sensing; satellite; sensor; SMOS; AMSR-2; TIR; numerical weather prediction; multiple regression analysis; Earth and Environmental Sciences;

   Abstract : The sea ice covers approximately 5% of the Earth’s surface at any given time and it plays an important role in the polar climate system affecting the heat, mass and momentum exchange between the atmosphere and the ocean. The snow cover on top of the sea ice affects its insulating and reflective properties and thus key figures in the climate system feedback loop. READ MORE

6. 25. Wind driven snow accumulation variability and terrain : Establishing a relationship by using GPR on Svalbard.

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Catharina Heerema; [2016]
   Keywords : snow accumulation; variability; GPR; terrain; wind; snöackumulation; variationer; terräng; vind; radar;

   Abstract : Snow accumulation patterns can be highly variable depending on terrain and wind. Knowledge of spatial variability of snow accumulation is of high relevance for mass balance modelling. READ MORE
