  2. 16. The Weichselian in southern Sweden and southwestern Baltic Sea : glacial stratigraphy, palaeoenvironments and deglaciation chronology

    Author : Johanna Anjar; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis the Weichselian glaciation history of southernmost Sweden and the southwestern Baltic Basin is discussed, with special emphasis on Middle and Late Weichselian ice advances and subsequent deglaciations. The main study area was Kriegers Flak in the southwestern Baltic Sea where pre-Late Weichselian sediments were identified. READ MORE

  4. 17. 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.

  5. 18. Glacial geology and palaeo-ice dynamics of two ice-sheet margins, Taymyr Peninsula, Siberia and Jameson Land, East Greenland

    Author : Helena Alexanderson; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ice dynamics; Pleistocene; Arctic Siberia; East Greenland; Sedimentology; Physical geography; Sedimentologi; pedology; geomorphology; klimatologi; kartografi; marklära; geomorfologi; cartography; Fysisk geografi; ice-marginal processes; glacial history; climatology;

    Abstract : The North Taymyr ice-marginal zone (NTZ) on the Taymyr Peninsula, Arctic Siberia and the Ugleelv Valley on Jameson Land, East Greenland, have been investigated with the aim of reconstructing the glacial history, including depositional processes and environments. Geomorphological, sedimentological, stratigraphical and remote sensing methods have been combined to give a comprehensive view of developments in the two areas. READ MORE

  6. 19. Glacial dynamics and till genesis in hilly terrain : A study in the Tallträsk area, central-northern Sweden

    Author : Hans Ivarsson; Mats Jansson; Per Möller; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; Physical geography; Naturgeografi;

    Abstract : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. READ MORE

  7. 20. The Eemian Interglacial at Sokli, northern Finland : A multi-proxy environmental and climatic reconstruction based on a 9 m long lacustrine sediment sequence

    Author : Anna Plikk; Karin F. Helmens; Oliver Heiri; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Last Interglacial MIS5e ; northern Europe; palaeolimnology; palaeoecology; temperature reconstruction; multiple proxies; climate dynamics; climatic events; kvartärgeologi; Quaternary Geology;

    Abstract : Understanding the fundamentals of the Earth’s climate system during the Quaternary Period (the past ca 2.6 million years) is of imminent interest in light of the reported recent climatic changes. READ MORE
