摘要ATM-9531397 Andrews，John University of科罗拉多，博尔德标题：冰岛西部和西北部的古气候（0 - 14 ka），比较 湖泊和近岸海洋代理记录：美国/冰岛 对P.A.L.E.的贡献 冰岛位于丹麦海峡东侧，海冰范围和持续时间的变化对海洋和陆地环境都有重大影响。 该区域监测大西洋水向北平流和东格陵兰海流中海冰和淡水向南流动的相对强度。 该PALE/ARCSS奖项支持从冰岛西北部湖泊中恢复一系列沉积物岩心，并将其气候代理记录与冰岛西北部峡湾和陆架槽的海洋岩心的代理记录进行比较。 根据早期的PALE研究，在这两种环境中，十年/百年采样分辨率是现实的，系统内以及湖泊和近海之间的相关性通过丰富的区域火山岩得到增强。 冰岛对赠款的一项主要贡献将包括在冰岛西北部沿沿着三个峡湾大陆架断面进行取样的船舶时间。

Abstract ATM-9531397 Andrews, John University of Colorado, Boulder Title: Paleoclimate (0 to 14 ka) of W and NW Iceland, A Comparison of Lake and Near-Shore Marine Proxy Records: A USA/Iceland Contribution to P.A.L.E. Iceland is located on the eastern side of Denmark Strait in a region where changes in the extent and duration of sea ice have major impacts on both the marine and terrestrial environments. This area monitors the relative strength of both the northward advection of Atlantic Water and the southward flux of sea ice and freshwater in the East Greenland Current. This PALE/ARCSS award supports the recovery of a series of sediment cores from lakes in NW Iceland and compares their proxy records of climate with proxy records from marine cores taken from fjords and shelf-troughs off northwestern Iceland. Based on earlier PALE studies, decadal/centennial sampling resolution is realistic in both environments, and correlations within systems and between lakes and the offshore are enhanced by an abundance of regional tephras. A major Icelandic contribution to the grant will include ship-time to carry out coring along three fjord shelf transects in northwestern Iceland.
