  1. 1. Jordlagerföljden i Höjeådalen utifrån nya borrningar

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Oskar Sundberg; [2021]
    Nyckelord :jordarter; jordartsutbredning; Weichsel; geologisk modell; Earth and Environmental Sciences;

    Sammanfattning : Jordarternas utbredning över sydvästra Skåne är ett resultat av Weichselistidens komplexa växelverkande isframstötar, där stora mäktiga kvartära avlagringar finns i anknytning till Alnarpssänkan och Lundadalen. Avlagringarna och deras glaciala ursprung är ett historiskt omdiskuterat ämne. LÄS MER

  3. 2. PLANT MIGRATION AT THE END OF THE WEICHSELIAN GLACIATION : Macrofossil evidence of early coniferous trees at two northern Swedish sites

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Karan Zakrzewski-Sharma; [2019]
    Nyckelord :Scandinavia; Weichselian; plant migration; macrofossils; climate change;

    Sammanfattning : Studies of vegetation history bring a new incentive to our understanding of plant survival and migration in arctic environments. For decades, environmental research was based on palynological data and these studies created a notion that tree species such as larch (Larix sibirica) and Scots pine (Pinus sylvestris) did not grow in northern Scandinavia at the end of Weichselian glaciation.

  4. 3. LiDAR-bildanalys av flutings i södra Norrbotten : Kartering och datering av avvikande isrörelseriktningar

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Sara Vallin; [2014]
    Nyckelord :Glacial flutes; flutings; digital elevation model; laser scanning; geographical information system; GIS; Weichselian; ice flow; northern Sweden; geomorphology; Flutings; nationell höjdmodell; laserskanning; LiDAR; GIS; Weichsel; isrörelseriktningar; Norrbotten; geomorfologi;

    Sammanfattning : The aim of this study was to map and date glacial flutings with ice flows deviating from the predominating northwesterly ice flow direction in the southern part of Norrbotten County in northern Sweden, and also to investigate if parts of the glacial landscape are older than previously thought. The traditional view is that most landforms in the area were formed during the late Weichselian (W3). LÄS MER

  5. 4. Moräntäckta rullstensåsar i Västerbottens inland

    Kandidat-uppsats, Institutionen för ekologi, miljö och geovetenskap

    Författare :Anna Lynam; [2013]
    Nyckelord :till-covered eskers; cold based deglaciation; late Weichselian; Västerbotten;

    Sammanfattning : The purpose of this study was to map the distribution of till-covered eskers in the inland of Västerbotten County in northern Sweden. The top layers of big eskers along the valleys of Öre River, Ume River and Vindel River were investigated through shallow digging. LÄS MER

  7. 5. A sedimentological and stratigraphical study of Veiki moraine in northernmost Sweden

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Þorbjörg Sigfúsdóttir; [2013]
    Nyckelord :Veiki moraine; glacial geology; Weichselian glaciation; northern Sweden; supraglacial lakes; Veikimorän; glacialgeologi; Weichselistiden; norra Sverige; supraglacial sjö; Earth and Environmental Sciences;

    Sammanfattning : Veiki moraine is a landform area consisting of rim-ridged subcircular hummocks and plateaus with depressions in between, mostly located within a N-S extending zone of a hummocky landscape. It is believed to have formed during the pre-late Weichselian and survived overriding by ice during the subsequent glaciations. LÄS MER
