Collaborative Research: Tree-Ring Based Records of Temperature and Glacial Fluctuation Spanning the Past Two Millennia, Prince William Sound, Alaska

摘要本研究的主要目的是建立一个连续的树木年轮年表，涵盖阿拉斯加南部威廉王子湾附近的活木和亚化石木。这个年表将提供过去两千年来北太平洋气候的年度确定记录。此外，长期树木年轮记录的发展将涉及到哥伦比亚和威廉王子湾周围其他冰川前进所杀死的树木的交叉测年；对这些冰川前野树木发芽和死亡日期的解释将使该地区的冰川波动能够以年代际精度重建。

AbstractThe primary objective of this research is to develop a continuous tree-ring chronology spanning the past 2000-years from living and subfossil wood around Prince William Sound, southern Alaska. This chronology will provide an annually resolved record of North Pacific climate for the past two-millennia. In addition, development of the long tree-ring record will involve cross-dating of trees killed by advances of Columbia and other glaciers around Prince William Sound; interpretation of the dates of tree germination and death on these glacier forefields will enable glacier fluctuations in the region to be reconstructed with decadal precision.
