Sea-level changes and pollen stratigraphy on the outer coast of Sunnmøre, western Norway
pp. 111-134

The sea-leve! history for the outermost coast of Sunnmøre was recorded by studying the litho- and palynomorph stratigraphy in eight palaeo-lakes. Deglaciation occurred around 12,600 BP and was followed by a rapid emergence. Then, during the late Allerød and Younger Dryas there was a longlasting stillstand. This suggests a slow and even eustatic sea-levet rise of less than 10 m during this time. A subsequent emergence started with the onset of the Holocene climatic amelioration around 10,200 BP. Radiocarbon dates from the Holocene were obtained from only one basin. The dates from this basin indicate that the Tapes transgression culminated before 8000 BP; however, many dates from neighbouring areas suggest a culmination around 6()()(}...7000BP. The Late Weichselian pollen stratigraphy has been subdivided into four assemblage zones which can easily be correlated with established zones for the Ålesund area. These include: Rumex/ Oxyria (12,600-12,000 BP), Betultr-Empetrum (12,000-11 ,000 BP), Salix-Artemisia (11,000-10,200 BP) and Betul?rluniperus-Empetrum assemblage zones. Climatic changes instigated the changes in vegetation associated with these zone boundaries.
