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

    Författare :Jona Finndis Jonsdottir; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 7. Land Degradation and Climate in Iceland - a spatial and temporal assessment

    Författare :Rannveig Olafsdottir; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spatial analysis; long-term analysis; Holocene; spatial simulations; Iceland; Geology; fysisk geografi; physical geography; Geologi; land cover; farmers perception; Land degradation;

    Sammanfattning : Degradation of vegetation and soil erosion has contributed to loss of biological productivity and land degradation in Iceland. This thesis focuses on spatial and temporal patterns of land degradation in Iceland from a geographical perspective both along short and long timescales. LÄS MER

  4. 8. Beyond a Second Demographic Transition? Fertility and family dynamics in Iceland

    Författare :Ari Klængur Jónsson; Gunnar Andersson; Gerda Neyer; Daniele Vignoli; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Family demography; Fertility; Family formation; Cohabitation; Nonmarital childbearing; Marriage; Marital dissolution; Iceland; Demography; demografi;

    Sammanfattning : This thesis serves to bring Iceland into the realm of Nordic family-demographic and fertility research. Based on event-history techniques applied to Iceland longitudinal register data, I provide an overview of contemporary family-demographic trends during the last few decades. The thesis consists of four empirical studies. LÄS MER

  7. 10. Fluid-rock interaction in two seismically active areas : The Tjörnes Fracture Zone, northern Iceland and the Shillong Plateau, northeastern India

    Författare :Lillemor Claesson; Alasdair Skelton; Steven Ingebritsen; Stockholms universitet; []
    Nyckelord :Tjörnes Fracture Zone; Shillong Plateau; Iceland; India; hydrogeochemical monitoring; earthquakes; geothermal; transition metals; dissolution; basalt; feldspar weathering; source switching; Geology; geologi;

    Sammanfattning : Hydrogeochemical monitoring can improve our understanding of fluid-rock interaction, and may detect anomalies that are precursory to- or caused by- earthquakes. In this study, hydrogeochemical monitoring was carried out in two distinct tectonic settings, to study coupling between hydrogeochemical changes and seismic activity. LÄS MER
