Relationship between deglacial climate change in the Northern and Southern Hemispheres remain clouded by uncertainties in the absolute timing and magnitude of the events recorded in the two hemispheres. The uncertainties are greatest in the Southern Hemisphere mid-latitudes where few well-dated records are available for comparison with the chronologies derived from Antarctica. Only details about the timing and magnitude of climate change from underrepresented areas in the Southern Hemisphere will clarify the relationships between the two hemispheres, and thus identify possible coupling mechanisms. The objective of this project is to establish the timing and magnitude of climate changes from climatically sensitive sites along the Southern Alps, New Zealand, by producing continuous, isotopically dated, pale-chironomid and pollen records.
