    Author : Katrin Lindbäck; Rickard Pettersson; Francisco Navarro; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate change; Greenland Ice Sheet; radio-echo sounding; digital elevation models; ice thickness; bed topography; spectral analysis; roughness; subglacial hydrology; water piracy; englacial features; drainage catchments; meltwater runoff; ice dynamics; klimatförändringar; Grönlands inlandsis; markbaserad radar; digitala höjdmodeller; istjocklek; bottentopografi; spektralanalys; subglacial hydrologi; englaciala strukturer; avrinningsområden; isdynamik;

    Abstract : The increased temperatures in the Arctic accelerate the loss of land based ice stored in glaciers. The Greenland Ice Sheet is the largest ice mass in the Northern Hemisphere and holds ~10% of all the freshwater on Earth, equivalent to ~7 metres of global sea level rise. READ MORE

  4. 2. Holocene climate and environmental dynamics on the Tristan da Cunha island group, South Atlantic

    Author : Karl Ljung; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; palynologi; Geology; climate change; pollen analysis; Palaeobotany; phylogeny; palynology; Paleobotanik; fylogeni; vegetation change; gyttja; peat; Holocene; Quaternary; South Atlantic; Tristan da Cunha; physical geography; Geologi; fysisk geografi;

    Abstract : It has been shown that the present interglacial has been climatically dynamic with both rapid and severe climatic fluctuations. The spatial and temporal differences of these changes are however not fully resolved. The aim of this thesis is to present a detail high resolution record of past climate changes from the central South Atlantic. READ MORE

  5. 3. On the role of migration for the distribution of arctic birds - a circumpolar perspective

    Author : Sara Henningsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bird migration; broad-scale distributions; geographic breeding range; geography of migration; non-breeding range; barriers to migration; Arctic birds; evolution of migration routes;

    Abstract : Flexibility as well as constraints to the evolution of migration routes has the possibility of affecting large-scale patterns of geographical ranges of animals both by facilitating, but sometimes restricting, accessibility to and colonization of new regions. This dissertation concerns the broad-scale effects migration has on the distributional patterns of birds in the Arctic. READ MORE
