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.

摘要这项研究的主要目标是利用阿拉斯加南部威廉王子湾周围的活木材和亚化石木材，建立一个跨越过去2000年的连续树木年轮年表。这份年表将提供过去两千年来北太平洋气候的年度解析记录。此外，开发长的树木年轮记录将涉及对哥伦比亚和威廉王子湾周围其他冰川推进而死亡的树木进行交叉测年；对这些冰川前场树木萌发和死亡日期的解释将使该地区的冰川波动能够以十年精度重建。
