  2. 1. Stormy records from peat bogs in south-west Sweden : implications for regional climatic variability and vegetation changes during the past 6500 years

    Author : Rixt de Jong; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Holocene climate; south-west Sweden; aeolian activity; humidity changes; vegetation development; REVEALS vegetation modelling; atmospheric circulation changes; peat sediments;

    Abstract : This thesis aims to reconstruct and explain variations in storm activity, humidity, vegetation composition and land cover in south-west Sweden during the past 6500 years. Two ombrotrophic bogs, Store Mosse and Undarsmosse, situated on the coastal plain of Halland, were selected for this purpose. READ MORE

  4. 2. Alpine lake sediment archives and catchment geomorphology : causal relationships and implications for paleoenvironmental reconstructions

    Author : Lena Rubensdotter; Gunhild Rosqvist; Ingmar Borgström; Eve Arnold; Jens-Ove Näslund; Catherine Souch; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alpine lakes; geomorphology; lacustrine sedimentation; slope processes; glaciofluvial; Holocene; Swedish Lapland; Physical geography; Naturgeografi;

    Abstract : Lake sediments are frequently used as archives of climate and environmental change. Minerogenic sediment variability in alpine lakes is often used to reconstruct past glacier and slope process activity. Alpine lake sediments can however have many different origins, which may induce errors in paleoenvironmental reconstructions. READ MORE

  5. 3. 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
