Eemian crustal deformation in the eastern Baltic area in the light of the new sites at Peski, Russia and Põhja-Uhtju, Estonia
Holocene vegetation history at Vätsäri, Inari Lapland, northeastern Finland, with special reference to Betula
A Holocene sediment series from a lake in the northern birch forest region of eastern Finnish Lapland was studied pollen-analytically. In addition to conventional pollen analysis, birch pollen measurements were carried out. Betula pollen diameters were measured systematically. The resulting size-frequency distributions were analysed statistically to infer their species composition and to reconstruct the local history of birch. The results indicat…
Holocene humidity changes in northern Finnish Lapland inferred from lake sediments and submerged Scots pines dated by tree-rings
Conclusive evidence for a rise in water levels has been found in connection with lake-sediment studies undertaken partly in collaboration with the pine megafossil sampling and dendrochronological work in northern Finnish Lapland. The change in lake-level stands is shown by slow sedimentation rate in the early to mid-Holocene and an increase thereafter. These data indicate a regional rise in water levels during the latter part of the Holocene foll…
Humic- and fulvic-acid stratigraphy of the Holocene sediments from a small lake in Finnish Lapland
Holocene sediments from a small lake (Hirvaslompolo) in eastern Finnish Lapland have been ana lysed for their content of humic substances. The amount and proportion of humic and fulvic acids were found to be subject to significant changes with time through the Holocene. The humus stratigraphy shows a good correlation with litho- and biostratigraphical indicators of environmental change at and around the site. The main vegetational changes were th…
Holocene lake-level changes in the Fennoscandian tree-line region, western Finnish Lapland
Lithostratigraphical, diatom and cladoceran evidence were used to demonstrate Holocene lake-level changes in two closed-basin lakes in western Finnish Lapland, north of the coniferous tree- line. The lake levels were significantly lower than present in early to mid-Holocene times, from about 8000 until about 4000BP, after which they rose to the present level. The changes are believed to be climatically controlled and regionally representative. Th…
