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. Water resources in Iceland - Impacts of climate variability and climate change

   Author : Jona Finndis Jonsdottir; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marklära; pedology; cartography; climatology; Fysisk geografi; geomorfologi; geomorphology; runoff map; projection of future runoff; Environmental studies; Miljöstudier; Physical geography; hydrological modelling; trends; climate change; climate variability; Iceland; water resources; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik; kartografi; klimatologi; Civil engineering; hydraulic engineering;

   Abstract : Hydropower is the main source of electricity production in Iceland. In 2005, 80.8% of all electricity was generated by hydropower (7015 GWh). Hydropower production is affected both by variations and changes in discharge. READ MORE

5. 3. 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

6. 4. 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

7. 5. Community and food web assembly on virgin habitat islands - The nunatak saga

   Author : Maria Ingimarsdottir; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; allochthonous material; arthropods; community assembly; corridor; dispersal; Iceland; metacommunity; nunataks; primary succession; stable isotopes.;

   Abstract : The classical view of primary community assembly is that colonisation by plants is essential before invertebrates can establish. It has been recognised, however, that invertebrates can establish before plants, and that they may be important in the first steps of community assembly. READ MORE
