Seppä H. Turvestratigrafisen tutkimuksen historiasta ja kvartaaritieteellisestä merkityksestä Pohjoismaissa.

Tiivistelmä

The early development of peat stratigraphical research was concentrated in the Nordic countries. Although this field of science originated in Denmark at the beginning of the 19th century, the most important pioneer of palaeoecological peatland research was the Norwegian, Axel Blytt. His model, as modified by the Swedish scientist Rutger Sernander, spread throughout Europe and from there to other continents and has had a major impact on peat stratigraphy and Quaternary science. However, our present knowledge of the regional differences in postglacial vegetation and climate history speaks against the use of the Blytt-Sernander scheme outside southern Scandinavia. Especially, the compulsive application of the Blytt-Sernander scheme in the zoning of pollen diagrams has lead to distortions and erroneous interpretations. Keywords: Nordic countries, peat stratigraphy, postglacial climate history, pollen analysis
