This action funds Jonathan Warnock of Northern Illinois University to conduct a research project, entitled "What are diatoms in the Southern Ocean telling us about sea ice change over the past 30 years," during the summer of 2012 at Macquarie University in Sydney, New South Wales. The host scientist is Leanne Armand.The Intellectual Merit of the research project is an increased understanding of the Southern Ocean's response to climate change. The study area, the Mertz Glacier polynya, is an area of active sea ice and bottom water creation. This bottom water provides the nutrients of the major upwelling zones in oceans, and fuels the marine food web. Diatoms, a prolific group of marine algae, provide the base of the record of ocean temperature and sea ice change in the past. Using diatoms collected over the past 30 years, and matching satellite records, this research identifies subtle changes in the Southern Ocean diatom record in the geologic past. This will in turn provide a better understanding of the magnitude of changes in warming oceans. 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.

这项行动资助了北伊利诺伊大学的乔纳森·沃诺克，他于2012年夏天在新南威尔士州悉尼的麦考瑞大学开展了一项名为“南大洋的硅藻告诉我们过去30年海冰变化的什么”的研究项目。主持的科学家是Leanne Armand。该研究项目的学术价值在于增进了对南大洋对气候变化的反应的了解。研究区域，默茨冰川多冰区，是一个活跃的海冰和底水形成的区域。这些底部的水为海洋中主要的上升流区提供营养，并为海洋食物网提供燃料。硅藻是一种多产的海洋藻类，为过去海洋温度和海冰变化的记录提供了基础。利用过去30年收集的硅藻，并与卫星记录相匹配，这项研究确定了地质过去南大洋硅藻记录的微妙变化。这将反过来更好地了解海洋变暖的变化幅度。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；介绍该地区的科学、科学政策和科学基础设施；以及对社会、文化和语言的了解。这些活动符合美国国家科学基金会的目标，即在其科学家、工程师和教育工作者的职业生涯早期培养国际合作，从而确保美国科学劳动力具有全球意识。
