Holocene palaeo-wind evidence from palynology in Baffin Island

Abstract

TRACE amounts of wind-blown tree pollen from the highly productive boreal coniferous forests are a characteristic component of arctic tundra sediments1,2. These exotic pollen are generally regarded as mere contamination or distractions in tundra pollen diagrams3. We report here that traces of exotic pollen in late Holocene sediments from Baffin Island can be used as palaeo-wind indicators, and may be associated with periodic shifts of a trough in the atmosphere.
