9321213 Calkin This award is for a three year study to investigate the subarctic climatic history as recorded largely in the tree-ring record and to precisely date glacial fluctuations of ice tongues terminating in, and occuring at, the margins of the deep, 50-km long fjords of Yakutat and Icy Bays of southeastern coastal Alaska. Chronologies drawn from 500 to 900 year old living trees cross-dated with logs of buried forests at multiple sites in each of the fjords, will provide the main basis for climatic reconstruction over the last two millenia. Climatic and glacial series together are expected to yield the first sound basis for testing response of fjord glaciers to climate change. ***

9321213 Calkin该奖项是一项为期三年的研究，旨在调查主要记录在树轮记录中的亚北极气候历史，并准确测定终止于雅库塔湾和阿拉斯加东南沿海冰湾的50公里长的深峡湾边缘的冰舌的冰川波动。从500到900年的活树绘制的年表与每个峡湾多个地点埋藏的森林的原木交叉测年，将为过去两千年的气候重建提供主要基础。气候和冰川系列预计将为测试峡湾冰川对气候变化的反应提供第一个可靠的基础。***
