2. 1. Dead-Ice Under Different Climate Conditions: Processes, Landforms, Sediments and Melt Rates in Iceland and Svalbard

   Author : Anders Schomacker; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; klimatologi; glacier; dead-ice; surge; ice-cored; Little Ice Age; fysisk geografi; Geologi; Geology; Svalbard; Iceland; Sedimentology; cartography; pedology; geomorphology; Sedimentologi; Physical geography; geomorfologi; marklära; kartografi; climatology;

   Abstract : Modern dead-ice environments in the glacier forefields of Brúarjökull, Iceland and Holmströmbreen, Svalbard were investigated with focus on landform and sediment genesis, as well as quantification of melting. Field monitoring and studies of multi-temporal aerial photographs, satellite imagery, and Digital Elevation Models (DEMs) provided data for the melting quantification. READ MORE

4. 2. Holocene development of Lake Lögurinn and Eyjabakkajökull : a multi-proxy approach

   Author : Johan Striberger; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Iceland; the Holocene; lake sediments; varves; glacial meltwater variability; surge periodicity; palaeoclimate;

   Abstract : The North Atlantic region has experienced significant climate fluctuations during the Holocene. It has been shown that these fluctuations affected the terrestrial environment in Iceland, including its glaciers and ice caps. READ MORE

5. 3. Response of glaciers to climate change : Mass balance sensitivity, sea level rise and runoff

   Author : Mattias de Woul; Regine Hock; Peter Jansson; Margareta Hansson; Roger J. Braithwaite; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; glacier; mass balance modelling; mass balance sensitivity; sea level rise; glacial runoff; Hofsjökull; Storglaciären; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

   Abstract : The purpose of this study is to enhance our understanding of the response of glaciers to climate change. Global sea level is affected by changes in glacier ice volume, and melt-water from glaciers is a principal water source in many regions. READ MORE

6. 4. Near surface atmospheric flow over high latitude glaciers

   Author : Oskar Parmhed; Erland Källén; Branko Grisogono; Haraldur Ólafsson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stable boundary layer; Ekman layer; Katabatic flow; gravity wave; low-level jets; Meteorology; Meteorologi;

   Abstract : In this thesis various descriptions of the near surface atmospheric flow over a high latitude glacier is used in an effort to increase our understanding of the basic flow dynamics there. Through their contribution to sea-level change, mountain glaciers play a significant role in Earth’s climate system. READ MORE

7. 5. Past dynamics of a marine-terminating glacier in lower Borgarfjörður, west Iceland - Analyses of glaciotectonic sediments and landforms

   Author : Thorbjorg Sigfusdottir; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; glacier dynamics; marine-terminating glacier; glaciomarine processes; thrust-block moraines; glaciotectonics; micromorphology; Early Holocene; Late Weichselian; Iceland;

   Abstract : Large and complete sections through glacial landforms formed in subaqueous environments are rare, impeding our knowledge of their internal composition and the processes responsible for their formation. Following the last deglaciation of the Icelandic Ice Sheet (IIS), a marine-terminating outlet glacier advanced out of the fjord of Borgarfjörður resulting in large-scale glaciotectonic deformation of glaciomarine sediments.
