1. 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 geovetenskapSammanfattning : 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.

2. Seismic activity and end- or post-glacial faults in northern Fennoscandia, focusing on Sweden
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : 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. LÄS MER
3. Stratigrafin i Hanöbukten under senaste glaciationen : en studie av borrkärnor från IODP’s expedition nr 347
Kandidat-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : The development of Hanö Bay during the last ice age has been investigated by analyzing cores from IODP’s Balitc Sea Palaeoenvironment expedition in the Baltic Sea. By analyzing the presence of Ice Rafted Debris, correlating one of the varved clay units to Ringbergs (1991)regional varve chronology from southeastern Sweden, analyzing pollen grains and measuring loss on ignition a few gaps in the history of Hanö Bay has been uncovered.

4. Borrning efter interstadiala sediment vid Ultevisplatån, Norrbotten
Kandidat-uppsats, Institutionen för naturgeografi och kvartärgeologi (INK)Sammanfattning : The purpose of this study is to find datable interstadial sediments in the core area of the LateWeicheslian ice sheet extent. Based on geomorphological evidence, three coring sites wereidentified close to the Ultevis plateau in Norrbotten, northern Sweden. LÄS MER
5. Ice advance-retreat sediment successions along the Logata River, Taymyr Peninsula, Arctic Siberia
Master-uppsats, Lunds universitet/Geologiska institutionenSammanfattning : A number of sites were investigated in river sections along the Logata River on the Taymyr Peninsula, Russia, and its adjacent areas to shed more light on the glaciation history over the last glacial cycles. The sediments exposed at the investigated sites are correlated and put into a local stratigraphic scheme divided into five main units. LÄS MER
