  2. 2. Palaeo-ice streams in the north-eastern Laurentide Ice Sheet

    Författare :Hernán De Angelis; Johan Kleman; Krister Jansson; Colm O'Cofaigh; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ice sheet; ice stream; palaeo-ice sheet; palaeo-ice stream; glaciology; palaeoglaciology; Laurentide Ice Sheet; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

    Sammanfattning : This thesis presents a palaeoglaciological study aimed to determine the location, geometry and temporal evolution of palaeo-ice streams of the north-easternmost Laurentide Ice Sheet. The work was accomplished through the geomorphological interpretation of satellite imagery over 3. LÄS MER

  3. 3. Relict non-glacial surfaces and autochthonous blockfields in the northern Swedish mountains

    Författare :Bradley W. Goodfellow; Arjen Stroeven; Clas Hättestrand; Johan Kleman; Krister Jansson; Adrian Hall; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; blockfield; chemical weathering; cosmogenic exposure dating; glaciated landscape; northern Sweden; periglacial geomorphology; relict surface; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Sammanfattning : Relict non-glacial surfaces occur in many formerly glaciated landscapes, where they represent areas that have escaped significant glacial modification. Frequently distinguished by blockfield mantles, relict non-glacial surfaces are important archives of long-term weathering and landscape evolution processes. LÄS MER

  4. 4. Comparison of dating methods for paleoglacial reconstruction in Central Asia

    Författare :Natacha Gribenski; Krister N. Jansson; Arjen P. Stroeven; Frank Preusser; Jonathan M. Harbor; Marc Bateman; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Paleoglaciation; Optically stimulated luminescence dating; Cosmogenic nuclide exposure dating; EMCCD camera; Physical Geography; naturgeografi;

    Sammanfattning : Reconstruction of former Central Asian glaciers extents can provide valuable information about past atmospheric circulation variations. These extents, often marked by terminal moraines, need to be chronologically constrained. Cosmogenic nuclide exposure (CNE) dating is widely used to directly date moraines. LÄS MER

  5. 5. How to deal with the encroachment costs in road investment CBA

    Författare :Pernilla Ivehammar; Jan Owen Jansson; Krister Hjalte; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; CBA; road investment; COPATS; cost transfer; encroachment; CVM; CBA; väginvesteringar; COPATS; cost transfer; intrång; CVM; Economics; Nationalekonomi;

    Sammanfattning : An important basis for decisions regarding road investments is Cost Benefit Analysis (CBA), where all costs and benefits should be taken into account and expressed in monetary terms. A valuation of the cost for the encroachment caused by a new road in, for example, a recreation area or a residential area is, however, missing in road investment CBA. LÄS MER
