This is a project to conduct geophysical surveys and acquire sediment cores from the fjords and continental shelf of southeastern Alaska. The data collected will be used to examine climatic variability in this region over the Holocene and Late Glacial interval. In particular, the study will determine if terrestrial climate changes in this region are linked to changes in regional ocean conditions and if decadal-scale climate changes, analogous to those in the historical record (referred to as the Pacific Decadal Oscillation"), are recorded in rapidly accumulating fjord sediments. If localities are discovered that yield important paleoclimatic records, these localities will be targeted in a drilling proposal for the Integrated Ocean Drilling Program.

该项目旨在进行地球物理调查并从阿拉斯加东南部的峡湾和大陆架获取沉积物岩心。收集的数据将用于检查该地区在全新世和晚冰期期间的气候变化。特别是，该研究将确定该地区的陆地气候变化是否与区域海洋条件的变化有关，以及是否记录了类似于历史记录中的十年尺度的气候变化（称为太平洋十年涛动）。如果发现产生重要古气候记录的地点，这些地点将成为综合海洋钻探计划钻探建议的目标。
