International Research Fellow Awards: Long-term Climate Dynamics in the Canadian Arctic; Paleoclimatic Reconstructions Using Fossil Midges from Long Cores (>20 ka)

9901893弗朗西斯国际研究员奖计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项提供了联合研究的机会，以及使用独特或互补的设施，专业知识和国外的实验条件。弗朗西斯与支持十二个月的工作与博士伊恩R。弗朗西斯博士将研究加拿大北极地区的长期气候动态。 她将通过研究从钻孔岩芯中发现的水生昆虫化石（摇蚊化石）来推断温度，从而开发一种新的气候变化代理记录。摇蚊的研究是一个非常有用的代用气候指标，这项研究将扩大和进一步发展其应用。 对巴芬岛长岩心（85，000年）的分析将有助于了解冰川事件的时间和程度。步行者博士研究摇蚊科已有20年，致力于将这一类群发展成为第四纪环境重建的重要工具。 他开发了一个摇蚊古温度推断模型，这将有利于这个研究项目。

9901893FrancisThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will provide Dr. Donna R. Francis with support for twelve months to work with Dr. Ian R. Walker at Okanagan University College in Kelowna, British Columbia.Dr. Francis will study long-term climate dynamics in the Canadian Artic. She will develop a novel proxy record for climate change through the study of aquatic insect fossils (chironomid remains) recovered from drill cores to infer temperature. Chironomid studies are a very useful proxy climate indicator and this research will extend and further develop their application. The analysis of long cores (85,000 years) from Baffin Island will help understand the timing and extent of glacial events.Dr. Walker has been working with chironomidae for 20 years and has worked to develop this group into a significant tool for Quaternary environmental reconstructions. He has developed a chironomid palaeotemperature inference model, which will benefit this research project.***
