    Abstract : New results are presented from the investigation of relative sea-level changes in the Nanortalik and Qaqortoq-Narsarsuaq areas in SW Greenland from c. 11 000 cal. years BP to the present. READ MORE

  2. 2. Glacial history of Northeast Greenland: cosmogenic nuclide constraints on chronology and ice dynamics

    University dissertation from Department of Geology, Lund University

    Author : Lena Håkanson; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Jameson Land; Store Koldewey; Scoresby Sund; Ice dynamics; Glacial history; Cosmogenic; Greenland Ice Sheet;

    Abstract : The aim of this thesis was to use cosmogenic exposure dating to investigating whether highly weathered landscapes in the Northeast Greenland fjord zone have developed during prolonged ice free conditions or have been preserved beneath cold-based ice. Previous work along the Northeast Greenland coast has presented two conflicting hypotheses for the extent of the Greenland Ice Sheet during the last glacial maximum (LGM). READ MORE

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

    University dissertation from Quaternary Sciences, Department of Geology, Lund University

    Author : Helena Alexanderson; [2002]
    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

  5. 5. Vegetation and climate during Weichselian ice free intervals in northern Sweden Interpretations from fossil and modern pollen records

    University dissertation from Stockholm : Institutionen för naturgeografi och kvartärgeologi

    Author : Martina Hättestrand; Ann-Marie Robertsson; Donatella Magri; ; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weichselian; interstadial; stadial; glacial history; northern Sweden; Tärendö; Riipiharju; Rissejauratj; Veiki moraine; pollen analysis; pollen deposition; pollen trap; PAR; NATURAL SCIENCES Earth sciences Exogenous earth sciences Quaternary geology; NATURVETENSKAP Geovetenskap Exogen geovetenskap Kvartärgeologi;

    Abstract : In this thesis the Weichselian history of northern Sweden is investigated, with emphasis on vegetation and climate during ice-free intervals. The main method used has been pollen analysis of sediments from pre-Late Weichselian landforms. To interpret fossil pollen assemblages, comparisons with modern pollen spectra were made. READ MORE
