Development of a Multi-Millennial Tree-Ring Chronology and Climate Reconstruction from the South Island of New Zealand

该奖项将有助于制作新西兰南岛银松几千年的年轮记录。这是南半球的一个地区，在那里很少有长全新世气候记录。基于已经建立的这种物种的温度敏感性，长年表将用于重建约3000年的南半球夏季温度记录。这一记录将提供对20世纪以前自然变率的估计。将进行实地工作，从奥罗科沼泽和以前有森林的地区收集古银松和亚化石木材的样本，目前正在清理和转变为奶牛场。这项研究有助于挽救一个重要的气候档案，否则它将因土地开发而丢失。

This award will help produce a multi-millennial tree-ring record of Silver Pine from South Island of New Zealand. This is an area of the southern hemisphere where long Holocene climate records are rare. Based upon an already established temperature sensitivity of this species, the long chronology will be used to reconstruct a ~3,000 year record of southern hemisphere summer temperatures. This record will provide estimates of natural variability prior to the 20th century. Field work will be undertaken to collect samples of ancient Silver Pine and sub-fossil wood from Oroko Swamp and areas previously forested and currently being cleared and converted to dairy farms. This research is helping salvage an important climate archive that would otherwise be lost due to land development.
