  1. 31. Simulating the palaeorecord of northern European lakes using a coupled lake-catchment model

    Författare :Jüri Vassiljev; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climatology; cartography; pedology; geomorphology; Physical geography; northern Europe; catchment geometry; Holocene; overflow lakes; climate change; Water- and energy-balance modelling; lake-level changes; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Sammanfattning : A coupled lake-catchment model was developed to examine the controls on lake-level changes in currently overflowing lakes during Holocene. The lake energy-balance is simulated as the one-dimensional vertical heat transfer by eddy diffusion and convective mixing. LÄS MER

  3. 32. The Littorina transgression in southeastern Sweden and its relation to mid-Holocene climate variability

    Författare :Shiyong Yu; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marklära; kartografi; Fysisk geografi; geomorfologi; climatology; cartography; pedology; geomorphology; Physical geography; tidal action; solar forcing; global meltwater pulse; North Atlantic storminess; climate changes; shoreline displacements; sea-level fluctuations; Littorina transgression; Baltic Sea; klimatologi;

    Sammanfattning : Lateglacial and Holocene shoreline displacement along the Baltic coast resulted from both the isostatic land uplift and the ice-volume-equivalent sea-level rise. Relative changes of these two components led to alternating contact/isolation of the Baltic Basin with the North Sea during the Holocene. LÄS MER

  4. 33. Hydrological aspects of the carbon balance in a boreal catchment: A model study

    Författare :Alla Yurova; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cartography; pedology; geomorphology; Physical geography; boreal peatland; dissolved organic carbon; ecohydrology; model; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : AbstractThe cycling of carbon in its gaseous, solid and dissolved forms is of central importance to ecosystem science, particularly, when the natural carbon cycle has been perturbed by human activity. Mathematical models are commonly used to asses and predict global and regional patterns of terrestrial carbon exchange. LÄS MER

  5. 34. Setting the Holocene clock using varved lake sediments in Sweden

    Författare :Lovisa Zillén; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; Physical geography; tephrochronology; palaeomagnetic secular variations; radiocarbon time-scale; Holocene varved lake sediments; varve chronology; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

    Sammanfattning : The aim of this thesis was to study annually laminated (varved) Holocene lake sediment in Sweden, their formation and their potential as chronological and palaeoecological archives. Five lakes with continuous Holocene varved lake sediment sequences in northern (Västerbotten) and west central Sweden (Värmland) were investigated. LÄS MER

  7. 35. Remnant echoes of the past : Archaeological geophysical prospection in Sweden

    Författare :Andreas Viberg; Kerstin Lidén; Bo Olofsson; Rinita Dalan; Bruce Bevan; Neil Price; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeological prospection; geophysical survey; Sweden; Ground-penetrating radar; magnetometry; Slingram; magnetic susceptibility; Neolithic; Migration period; Viking Age; Middle Ages; Öland; Gotland; Sigtuna; Lapland; Archaeological Science; laborativ arkeologi;

    Sammanfattning : The aim of this thesis has been to investigate the benefits, pitfalls and possibilities of using geophysical methods in archaeological projects. This is exemplified by surveys carried out at archaeological sites in different geographical and chronological contexts. LÄS MER
