DESCRIPTION: A region detailed chronology of glacial pulses during the Holocene will developed for New Zealand's Southern Alps by 10Be surface exposure dating moraines from both the eastern and western flanks of New Zealand and from both large glacier valleys and small glacier valleys in order to better understand climate instability during the Holocene and its affects on humans.

OUTCOMES: Found that New Zealand's Southern Alp's glaciers showed anti-symmetric patterns compared to northern glaciers, however northern and southern glaciers have been retreating in sync over the last 150 years. This has shown that there was not a "global Little Ice Age" and that anthropogenic forcing has surpassed the natural inter-hemispherically anti-phased climate pattern.
