An Ice Core Derived Multivariate Proxy Record of Holocene Climate Change from the Penny Ice Cap, Baffin Island, Canada

该奖项支持新罕布什尔大学的一个美国研究小组参与一项国际合作，收集和研究加拿大巴芬岛Penny冰帽上约500米长的冰芯。该项目由加拿大地质调查局和日本国立极地研究所共同完成。野外工作除了收集和分析500米长的主要岩心外，还包括对雪坑和浅岩心的研究。该奖项支持的实验室工作包括主要离子（钠、铵、钾、镁、钙、氯化物、硝酸盐和硫酸盐）、不溶性微粒和甲烷磺酸的分析。这些数据将与在加拿大和日本收集的分析数据相结合，完整的分析数据将用于构建巴芬岛全新世气候和环境条件的代理记录。彭尼冰盖的这些数据将补充格陵兰冰盖项目（GISP）的记录：具体来说，这些数据将提供有关低海拔地区气候条件的信息，从而可以与GISP冰芯的解释进行有用的比较。＊＊＊

9322045 Zielinski This award supports participation by a US research team from the University of New Hampshire in an international collaborative effort to collect and study an approximately 500 meter long ice core from the Penny Ice Cap on Baffin Island, Canada. This project is collaborative with the Geological Survey of Canada and Japan s National Institute of Polar Research. Field work includes study of snow pits and shallow cores in addition to collection and analysis of the main 500 meter long core. Laboratory work supported by this award includes analysis of major ions (sodium, ammonium, potassium, magnesium, calcium, chloride, nitrate, and sulfate), insoluble microparticles and methanesulfonic acid. These data will be integrated with analytical data collected in Canada and Japan and the complete set of analyses will be used to construct a proxy record of climate and environmental conditions for Baffin Island for the Holocene. These data from the Penny Ice Cap will complement records from the Greenland Ice Sheet Project (GISP): specifically, these data will provide information about climatic conditions at lower elevations that will allow a useful comparison to interpretations from the GISP cores. ***
