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

   Author : Martina Hättestrand; Ann-Marie Robertsson; Donatella Magri; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Weichselian; interstadial; stadial; glacial history; northern Sweden; Tärendö; Riipiharju; Rissejauratj; Veiki moraine; pollen analysis; pollen deposition; pollen trap; PAR; Quaternary geology; 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

5. 8. Marginal behaviour of the last Scandinavian Ice Sheet during its final termination and deglaciation over Northeastern Germany

   Author : Joachim Albrecht; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; Marginal dome; Deglaciation; Clast lithology; Clast fabric; Germany; Pomeranian; Weichselian; Lithostratigraphy; marklära; kartografi; klimatologi; Sedimentology; Sedimentologi;

   Abstract : This thesis presents results from studies on geomorphology, lithostratigraphy and ice flow patterns during the final termination and deglaciation of the last Scandinavian Ice Sheet in NE Germany. Ice flow patterns derived from till fabrics and glaciotectonical data indicate that short-lived marginal domes had formed during the advance and the retreat of the last Scandinavian Ice Sheet in NE Germany.

6. 9. Mountain centered icefields in northern Scandinavia

   Author : Ola Fredin; Clas Hättestrand; Arjen Stroeven; Peter Jansson; Johan Kleman; Jon Landvik; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Scandinavia; Quaternary; Weichselian; mountain; icefield; ice sheet; Physical geography; Naturgeografi;

   Abstract : Mountain centered glaciers have played a major role throughout the last three million years in the Scandinavian mountains. The climatic extremes, like the present warm interglacial or cold glacial maxima, are very short-lived compared to the periods of intermediate climate conditions, characterized by the persistence of mountain based glaciers and ice fields of regional size.

7. 10. 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
