1. 1. Surface crevasses on Svalbard: Spatial Distribution Analysis with Focus on the Lomonosovfonna Ice Cap

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Monika Hawrylak; [2021]
   Nyckelord :crevasses; spatial distribution; model; glacier velocity; Lomonosovfonna; Svalbard;

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

   Författare :Elena Serra; [2017]
   Nyckelord :;

   Sammanfattning : Paleoglaciological reconstructions based on glacial geological and geomorphological evidence areused to constrain and test numerical models of ice sheet extent and dynamics. The MAGIC-DMLresearch project (“Mapping, Measuring and Modelling Antarctic Geomorphology and Ice Change, inDronning Maud Land”) is trying to reconstruct the timing and pattern of ice surface elevation changessince the mid-Pliocene across western Dronning Maud Land, East Antarctica.

5. 4. Calving front dynamics : External forces that lead to specific sized calving events

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Daniel Wainwright; [2014]
   Nyckelord :Greenland; calving; climate; photography; glacier; tidewater;

   Sammanfattning : Currently there is no extended study that explicitly focuses on themagnitude, frequency and timing of glacial calving resulting from externalforces. Past studies have identified the size and timing of calving events butthe links between them and the external factors that cause them are stillmissing. LÄS MER

7. 5. Upper Triassic depositional environments at Lunnom, northwest Scania

   Magister-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Erik Svensson; [1989]
   Nyckelord :geography; geology; Scania; Lunnom; Upper Triassic; mid-Rhaetic; Limbosporites-Rhaetipollis miospore Zone; high energy events; crevasse; non-marine; alluvial plain; Earth and Environmental Sciences;

   Sammanfattning : The mid-Rhaetic sequence at Lunnom, with coal and kaolinitic clays, indicates partly deltaic environments affected by alluvial processes during humid conditions. Of special interest is a thin bed of sandstone with coarse, angular quartz grains. LÄS MER
