1. 1. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

   University essay from Umeå universitet/Institutionen för fysik

   Author : Petter Ideström; [2023]
   Keywords : Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

   Abstract : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. READ MORE

3. 2. Analysing seasonal snow cover trends and patterns on Svalbard

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

   Author : Dhruv Maniktala; [2022]
   Keywords : snow cover; snow disappearance; snow onset; snow-free duration; CARRA; Svalbard;

   Abstract : Rapid warming in the Arctic is highly impacting the cryosphere in the region, causing melting of the sea ice, retreat of glaciers and reduction in the snow cover. If suffering further temperature increase, the albedo of the region would reduce due to higher absorption of the solar radiation in snow-free areas. READ MORE

4. 3. Foreland evolution of Blåisen, Norway, over the course of an ablation season

   University essay from Lunds universitet/Geologiska institutionen

   Author : Alexander Hamilton-Foyn; [2020]
   Keywords : Geomorphological Mapping; Structure from Motion; Glacial Landforms; Ice-Marginal Landforms; Landform Preservation; Hardangerjøkulen; Norway; Earth and Environmental Sciences;

   Abstract : This study presents a detailed investigation into the evolution of sedimentary landforms over an ablation season at Blåisen, an outlet of the Hardangerjøkulen Icecap, Norway. The two visits to Blåisen, one each side of the ablation season, allowed the preservation and evolution of the landforms to be studied. READ MORE

5. 4. Assessing evolution of ice caps in Suðurland, Iceland, in years 1986 - 2014, using multispectral satellite imagery

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Alicja Miodonska; [2019]
   Keywords : remote sensing; multispectral satellite imagery; Landsat; Iceland; glaciers; ice caps; Geography; GIS; Earth and Environmental Sciences;

   Abstract : The study focuses on the application of multispectral satellite imageries in glaciological studies. It aims to assess how the Icelandic glaciers have evolved over the last decades (from the 1980s to 2014). The study area covers Mýrdalsjökull and Eyjafjallajökull ice caps located in Suðurland, Iceland. READ MORE

6. 5. Snow insulation effects across the Arctic : evaluating a revised snow module in LPJ-GUESS

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Alexandra Pongrácz; [2019]
   Keywords : active layer depth; Arctic; LPJ-GUESS; snow; soil temperature; Earth and Environmental Sciences;

   Abstract : The effect of future changes in temperature and precipitation patterns on arctic ecosystem functioning is often assessed using state-of-the-art ecosystem models. Many models however lack detailed representation of wintertime processes, as pointed out by recent studies (Wang et al. 2016, Slater and Lawrence 2013). READ MORE
