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

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

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

    Abstract : 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.

  3. 2. Seismic activity and end- or post-glacial faults in northern Fennoscandia, focusing on Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Kie Oyama; [2016]
    Keywords : Fennoscandia; seismicity; end post-glacial fault; deglaciation; glacial uplift;

    Abstract : During the late or post Weichselian glacial periods, about 9500 years ago, several faulting associated with large scale earthquakes were triggered in northern Fennoscandia. The end- or post-glacial scarps have a range of the lengths c. 3 to 155 km and the heights 0 to 30 m while most of them are reverse faults trending NE-SW with SE dips. READ MORE

  4. 3. Geophysical Mapping around Björkö Island in Lake Mälaren, South central Sweden

    University essay from Institutionen för geologiska vetenskaper

    Author : Oscar Fransner; [2013]
    Keywords : Marine geosciences; geophysics; archeology; Birka; Mälaren; subbottom profiling; sediment stratigraphy; multibeam echosounder; backscatter; angular range analysis; shipwrecks.;

    Abstract : The former Viking settlement Birka is located on Björkö Island in Lake Mälaren, the third largest lake in Sweden. Birka is a well-known archeological site that onshore has been carefully examined. READ MORE

  5. 4. Near-surface stratigraphy of till and glacifluvium near Knaften, northern Sweden : Identifying small-scale stratigraphy using ground-penetrating radar

    University essay from Institutionen för ekologi, miljö och geovetenskap

    Author : Holger Jacobson; [2013]
    Keywords : Ground-penetrating radar; small scale; near surface; stratigraphy; late Weichselian; grain-size comparison;

    Abstract : The aim of the study was to assess the possibilities in using ground-penetrating radar to identify small-scale stratigraphy in the upper 1 m of a soil profile and to statistically identify differences in the stratigraphic units discovered using the GPR unit. The study area is ca 15 km southwest of Lycksele near a gravel pit on the banks of Örån. READ MORE

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

    University essay from Lunds universitet/Geologiska institutionen

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

    Abstract : 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. READ MORE
