NSF East Asia and Pacific Summer Institute (EAPSI) for FY 2013 in Australia

这一行动资助密苏里大学的佩奇·昆顿于2013年夏天在悉尼新南威尔士州地质调查局开展了一个地球科学研究项目。该项目的标题是“在澳大利亚新南威尔士州晚奥陶世时期限制全球海面温度趋势”。该项目利用从澳大利亚新南威尔士州采集的牙形刺元素(位于小型海洋动物鳃中的牙齿状结构，称为牙形刺)，建立了澳大利亚大陆晚奥陶世(4.54至4.43亿年前)第一个高分辨率的海表面温度记录。以前沿着这些路线进行的工作主要是在北美的岩石上进行的，因此很难确定观察到的模式是全球性的还是区域性的。这些结果对大气二氧化碳在气候演化中的作用、奥陶纪冰川作用的时间以及冰川作用与奥陶纪末期大灭绝事件的关系具有重要意义。此外，有关全球气候的知识具有社会相关性。管理过去全球气候变化的机制，今天仍在继续。更好地了解它们将有助于更好地预测未来可能发生的变化，特别是在长期范围内。EAPSI奖学金的广泛影响包括为研究员提供美国以外的第一手研究经验；介绍各自所在地的科学、科学政策和科学基础设施；以及对社会、文化和语言的定位。这些活动符合NSF的目标，即在其科学家、工程师和教育工作者的职业生涯早期为国际合作进行教育，从而确保拥有一支具有全球意识的美国科学队伍。此外，研究员获得的知识和经验将在她教授的课程中告知和丰富学生的教育经验，重点是根除对气候系统行为的误解和误解。

This action funds Page Quinton of The University of Missouri to conduct a research project in Geoscience during the summer of 2013 at the Geological Survey of New South Wales in Sydney. The project title is "Constraining Global Sea Surface Temperatures Trends during the Late Ordovician Period in New South Wales Australia." The host scientist is Dr. Ian Percival.This project establishes the first high-resolution sea surface temperature record of the Australian continent during the Late Ordovician (a time period from 454 to 443 million years ago) using conodont elements (the teeth-like structures located in the gills of a small marine animal, referred to as conodonts) collected from New South Wales, Australia. Previous work along these lines has largely been conducted on rocks from North America making it difficult to determine if observed patterns were global or regional. These results have implications for the role atmospheric carbon dioxide on climate evolution, the timing of Ordovician glaciation, and the relationship between glaciation and the mass extinction event at the end of the Ordovician Period. Furthermore, knowledge of the global climate has societal relevance. Mechanism which governed past changes in global climate, continue to do so today. A better understanding of them will contribute to better predictions of possible changes going forward especially on a long time scale.Broader impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce. In addition, the knowledge and experience gained by the Fellow will inform and enrich educational experience of the students in the courses she teaches with an emphasis on uprooting misconceptions and misunderstandings about the behavior of climatic systems.
