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陆地部分地区进行冰化学调查的项目，目的是了解年至数百年尺度的气候变化。将收集的冰化学数据将为国际跨南极科学考察队的美国部分做出贡献，并将在为期两年的陆上穿越中进行，该穿越将从维多利亚北部的泰勒圆顶开始，然后到达南极。这些数据，以及在西南极早期一系列导线上收集的类似信息，将有助于深入了解自然气候变异性，并将为在人类活动背景下评估现代气候变异性提供基准；并有助于预测未来的气候变异性。通过选择合适的采样地点，导线将对了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。美国的ITASE研究解决了有关南极洲在全球变化中的作用的重要问题，并将对国际基础科学年做出重要贡献。结果通过讲座、媒体露面以及缅因州大学和(波士顿)科学博物馆之间的一项重大推广活动转化为可公开获取的信息。美国ITASE活动为K-12教育和大学课程的课程开发提供了材料，并为研究生和本科生提供了实地和实验室体验的机会。气候变化研究所在性别和种族多样化的学生和教职员工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.
