US ITASE Glaciochemistry Phase 2: East Antarctica

该奖项支持对罗斯海海湾排水系统和威尔克斯地部分地区进行冰川化学调查的项目，目的是了解每年到百年尺度的气候变化。将收集的冰川化学数据将为国际跨南极科学考察的美国组成部分做出贡献，并将在两年的时间内进行陆上穿越，从维多利亚北部的泰勒多姆开始，前往南极。这些数据，连同早先在西南极洲进行的一系列穿越所收集的类似信息，将有助于深入了解自然气候变率，并将为评估人类活动背景下的现代气候变率提供基线；对未来气候变化的预测也有贡献。通过选择合适的采样地点，穿越将对理解主要大气现象的行为做出重要贡献，如南极涛动、ENSO和大气化学成分的变化，以及对所有这些变化的控制。美国ITASE的研究涉及有关南极洲在全球变化中的作用的重要问题，并将对国际极地年作出重要贡献。结果通过讲座、媒体露面以及缅因大学和科学博物馆（波士顿）共享的主要外展活动转化为可公开访问的信息。美国ITASE活动为K-12教育和大学课程的课程开发提供材料，并为研究生和本科生提供实地和实验室经验的机会。气候变化研究所在性别和种族多样化的学生和工作人员参与研究方面有着悠久的历史。

This award supports a project to undertake glaciochemical investigations of the Ross Sea Embayment Drainage System, and portions of Wilkes Land for purposes of understanding annual to multi-centennial scale climate variability. The glaciochemical data that will be collected will contribute to the U.S. component of the International Trans-Antarctic Scientific Expedition and will occur over a period of two years on an overland traverse that will begin at Taylor Dome in Northern Victoria Land and travel to the South Pole. This data, along with similar information collected on a series of earlier traverse in West Antarctica, will contribute to providing an in-depth understanding of natural climate variability and will provide a baseline for assessing modern climate variability in the context of human activity; and a contribution to the prediction of future climate variability. By choosing appropriate sites for sampling, the traverse will make important contributions to the understanding of the behavior of major atmospheric phenomena such as the Antarctic Oscillation, ENSO, and changes in the chemical composition of the atmosphere, plus controls on all of these changes. US ITASE research addresses important questions concerning the role of Antarctica in global change and will make an important contribution to IPY. Results are translated into publicly accessible information through lectures, media appearances, and a major outreach activity shared between the University of Maine and the Museum of Science (Boston). US ITASE activities provide material for curriculum development in K-12 education and university courses and opportunities for field and laboratory experiences for graduate and undergraduate students. The Climate Change Institute has a long history of gender and ethnically diverse student and staff involvement in research.
