Abstract

Twenty pollen records from the midwestern United States were investigated using two methods of time series analysis in order to characterize Holocene climatic variability in this region. Event correlation among the twenty pollen records suggested that change in vegetation, and thus in climate, was episodic during the Holocene and was most substantial during the period between 11 500 and 10 000 yr BP. Analysis of six of these pollen records revealed that a portion of the Holocene climate variability in the Midwest may have been quasi-periodic with a central frequency of approximately 1 cycle/1100 years. These preliminary results suggest that vegetation change in the century and millennium frequency bands must be considered in the context of systematic century- and millennium-scale climatic change. - from Author
