1. 1. 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

3. 2. Geothermal function integration in ice rinks with CO2 refrigeration system

   University essay from KTH/Tillämpad termodynamik och kylteknik

   Author : Juris Pomerancevs; [2019]
   Keywords : Ice rinks; CO2 refrigeration system; geothermal energy; heat recovery.; Ishallar; CO2 kylsystem; geoenergi; värmeåtervinning;

   Abstract : Ice rinks are energy intense industrial applications. A typical single sheet ice rink in Sweden uses about 1000 MWh/season. A state-of-the art ice rink systems can use less than 500 MWh/season, indicating the potential for improvements. READ MORE

4. 3. Numerical ice sheet modelling using FEniCS

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : André Löfgren; [2019]
   Keywords : ;

   Abstract : The increase in computational power in the last 20 years has made it feasible to solve the full Stokes equation for ice flow, using finite element methods (FEM). However, the numerical properties of these equations remains largely unknown. This is due to their nonlinear nature, which makes them hard to analyze mathematically. READ MORE

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

   University essay from Uppsala universitet/Institutionen för geovetenskaper

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

   Abstract : 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. READ MORE

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

   University essay from

   Author : Taisiya Dymova; [2018]
   Keywords : ;

   Abstract : 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.
