The potential of New Zealand kauri (Agathis australis) for testing the synchronicity of abrupt climate change during the Last Glacial Interval (60,000–11,700 years ago)

Turney, Chris S.M.; Fifield, L. Keith; Hogg, Alan G.; Palmer, Jonathan G.; Hughen, Konrad A.; Baillie, Mike G.L.; Galbraith, Rex; Ogden, John; Lorrey, Andrew; Tims, Stephen G.; Jones, Richard T. (Elsevier, 2010)

The latter part of the Last Glacial Interval (LGI; 60,000 to 11,700 years ago) experienced a range of climatic and environment extremes. To elucidate the mechanisms of these changes requires records of past variability ...
Towards a radiocarbon calibration for oxygen isotope stage 3 using New Zealand kauri (Agathis australis)

Turney, Chris S.M.; Fifield, L. Keith; Palmer, Jonathan G.; Hogg, Alan G.; Baillie, Mike G.L.; Galbraith, Rex; Ogden, John; Lorrey, Andrew; Tims, Stephen G. (University of Arizona, Department of Geosciences, 2007)

It is well known that radiocarbon years do not directly equate to calendar time. As a result, considerable effort has been devoted to generating a decadally resolved calibration curve for the Holocene and latter part of ...
