Modern and Holocene Pollen Assemblages from Some Small Arctic Lakes on Somerset Island, NWT, Canada
Abstract Modern pollen samples from 15 lakes along a north-south transect on western Somerset Island, NWT, Canada, show a decrease in pollen concentrations from the high arctic to the mid-arctic zone, but there are few differences in the pollen percentages between these sites.
