The team will use 10Be and 14C dating to measure transects of cosmogenic nuclide concentrations from newly exposed bedrock to explore its potential as a climate archive. This will help determine if glaciers were smaller than today during the Holocene, if so for how long, and if there is an inter-hemispheric pattern to these warm periods.
OUTCOMES: Evidence of low cosmogenic nuclides suggests that New Zealand's glaciers were never as small as now during the Holocene, while glaciers in the Alps were smaller than today in the early Holocene when insolation was higher. Five journal publications and one website.
